======== Settings ======== .. contents:: :local: :depth: 1 .. warning:: Be careful when you override settings, especially when the default value is a non-empty list or dictionary, such as :setting:`STATICFILES_FINDERS`. Make sure you keep the components required by the features of Django you wish to use. Core Settings ============= Here's a list of settings available in Django core and their default values. Settings provided by contrib apps are listed below, followed by a topical index of the core settings. For introductory material, see the :doc:`settings topic guide `. .. setting:: ABSOLUTE_URL_OVERRIDES ``ABSOLUTE_URL_OVERRIDES`` -------------------------- Default: ``{}`` (Empty dictionary) A dictionary mapping ``"app_label.model_name"`` strings to functions that take a model object and return its URL. This is a way of inserting or overriding ``get_absolute_url()`` methods on a per-installation basis. Example:: ABSOLUTE_URL_OVERRIDES = { 'blogs.weblog': lambda o: "/blogs/%s/" % o.slug, 'news.story': lambda o: "/stories/%s/%s/" % (o.pub_year, o.slug), } The model name used in this setting should be all lowercase, regardless of the case of the actual model class name. .. setting:: ADMINS ``ADMINS`` ---------- Default: ``[]`` (Empty list) A list of all the people who get code error notifications. When :setting:`DEBUG=False ` and :class:`~django.utils.log.AdminEmailHandler` is configured in :setting:`LOGGING` (done by default), Django emails these people the details of exceptions raised in the request/response cycle. Each item in the list should be a tuple of (Full name, email address). Example:: [('John', 'john@example.com'), ('Mary', 'mary@example.com')] .. setting:: ALLOWED_HOSTS ``ALLOWED_HOSTS`` ----------------- Default: ``[]`` (Empty list) A list of strings representing the host/domain names that this Django site can serve. This is a security measure to prevent :ref:`HTTP Host header attacks `, which are possible even under many seemingly-safe web server configurations. Values in this list can be fully qualified names (e.g. ``'www.example.com'``), in which case they will be matched against the request's ``Host`` header exactly (case-insensitive, not including port). A value beginning with a period can be used as a subdomain wildcard: ``'.example.com'`` will match ``example.com``, ``www.example.com``, and any other subdomain of ``example.com``. A value of ``'*'`` will match anything; in this case you are responsible to provide your own validation of the ``Host`` header (perhaps in a middleware; if so this middleware must be listed first in :setting:`MIDDLEWARE`). Django also allows the `fully qualified domain name (FQDN)`_ of any entries. Some browsers include a trailing dot in the ``Host`` header which Django strips when performing host validation. .. _`fully qualified domain name (FQDN)`: https://en.wikipedia.org/wiki/Fully_qualified_domain_name If the ``Host`` header (or ``X-Forwarded-Host`` if :setting:`USE_X_FORWARDED_HOST` is enabled) does not match any value in this list, the :meth:`django.http.HttpRequest.get_host()` method will raise :exc:`~django.core.exceptions.SuspiciousOperation`. When :setting:`DEBUG` is ``True`` and ``ALLOWED_HOSTS`` is empty, the host is validated against ``['.localhost', '127.0.0.1', '[::1]']``. ``ALLOWED_HOSTS`` is also :ref:`checked when running tests `. This validation only applies via :meth:`~django.http.HttpRequest.get_host()`; if your code accesses the ``Host`` header directly from ``request.META`` you are bypassing this security protection. .. setting:: APPEND_SLASH ``APPEND_SLASH`` ---------------- Default: ``True`` When set to ``True``, if the request URL does not match any of the patterns in the URLconf and it doesn't end in a slash, an HTTP redirect is issued to the same URL with a slash appended. Note that the redirect may cause any data submitted in a POST request to be lost. The :setting:`APPEND_SLASH` setting is only used if :class:`~django.middleware.common.CommonMiddleware` is installed (see :doc:`/topics/http/middleware`). See also :setting:`PREPEND_WWW`. .. setting:: CACHES ``CACHES`` ---------- Default:: { 'default': { 'BACKEND': 'django.core.cache.backends.locmem.LocMemCache', } } A dictionary containing the settings for all caches to be used with Django. It is a nested dictionary whose contents maps cache aliases to a dictionary containing the options for an individual cache. The :setting:`CACHES` setting must configure a ``default`` cache; any number of additional caches may also be specified. If you are using a cache backend other than the local memory cache, or you need to define multiple caches, other options will be required. The following cache options are available. .. setting:: CACHES-BACKEND ``BACKEND`` ~~~~~~~~~~~ Default: ``''`` (Empty string) The cache backend to use. The built-in cache backends are: * ``'django.core.cache.backends.db.DatabaseCache'`` * ``'django.core.cache.backends.dummy.DummyCache'`` * ``'django.core.cache.backends.filebased.FileBasedCache'`` * ``'django.core.cache.backends.locmem.LocMemCache'`` * ``'django.core.cache.backends.memcached.PyMemcacheCache'`` * ``'django.core.cache.backends.memcached.PyLibMCCache'`` You can use a cache backend that doesn't ship with Django by setting :setting:`BACKEND ` to a fully-qualified path of a cache backend class (i.e. ``mypackage.backends.whatever.WhateverCache``). .. versionchanged:: 3.2 The ``PyMemcacheCache`` backend was added. .. setting:: CACHES-KEY_FUNCTION ``KEY_FUNCTION`` ~~~~~~~~~~~~~~~~ A string containing a dotted path to a function (or any callable) that defines how to compose a prefix, version and key into a final cache key. The default implementation is equivalent to the function:: def make_key(key, key_prefix, version): return ':'.join([key_prefix, str(version), key]) You may use any key function you want, as long as it has the same argument signature. See the :ref:`cache documentation ` for more information. .. setting:: CACHES-KEY_PREFIX ``KEY_PREFIX`` ~~~~~~~~~~~~~~ Default: ``''`` (Empty string) A string that will be automatically included (prepended by default) to all cache keys used by the Django server. See the :ref:`cache documentation ` for more information. .. setting:: CACHES-LOCATION ``LOCATION`` ~~~~~~~~~~~~ Default: ``''`` (Empty string) The location of the cache to use. This might be the directory for a file system cache, a host and port for a memcache server, or an identifying name for a local memory cache. e.g.:: CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.filebased.FileBasedCache', 'LOCATION': '/var/tmp/django_cache', } } .. setting:: CACHES-OPTIONS ``OPTIONS`` ~~~~~~~~~~~ Default: ``None`` Extra parameters to pass to the cache backend. Available parameters vary depending on your cache backend. Some information on available parameters can be found in the :ref:`cache arguments ` documentation. For more information, consult your backend module's own documentation. .. setting:: CACHES-TIMEOUT ``TIMEOUT`` ~~~~~~~~~~~ Default: ``300`` The number of seconds before a cache entry is considered stale. If the value of this settings is ``None``, cache entries will not expire. .. setting:: CACHES-VERSION ``VERSION`` ~~~~~~~~~~~ Default: ``1`` The default version number for cache keys generated by the Django server. See the :ref:`cache documentation ` for more information. .. setting:: CACHE_MIDDLEWARE_ALIAS ``CACHE_MIDDLEWARE_ALIAS`` -------------------------- Default: ``'default'`` The cache connection to use for the :ref:`cache middleware `. .. setting:: CACHE_MIDDLEWARE_KEY_PREFIX ``CACHE_MIDDLEWARE_KEY_PREFIX`` ------------------------------- Default: ``''`` (Empty string) A string which will be prefixed to the cache keys generated by the :ref:`cache middleware `. This prefix is combined with the :setting:`KEY_PREFIX ` setting; it does not replace it. See :doc:`/topics/cache`. .. setting:: CACHE_MIDDLEWARE_SECONDS ``CACHE_MIDDLEWARE_SECONDS`` ---------------------------- Default: ``600`` The default number of seconds to cache a page for the :ref:`cache middleware `. See :doc:`/topics/cache`. .. _settings-csrf: .. setting:: CSRF_COOKIE_AGE ``CSRF_COOKIE_AGE`` ------------------- Default: ``31449600`` (approximately 1 year, in seconds) The age of CSRF cookies, in seconds. The reason for setting a long-lived expiration time is to avoid problems in the case of a user closing a browser or bookmarking a page and then loading that page from a browser cache. Without persistent cookies, the form submission would fail in this case. Some browsers (specifically Internet Explorer) can disallow the use of persistent cookies or can have the indexes to the cookie jar corrupted on disk, thereby causing CSRF protection checks to (sometimes intermittently) fail. Change this setting to ``None`` to use session-based CSRF cookies, which keep the cookies in-memory instead of on persistent storage. .. setting:: CSRF_COOKIE_DOMAIN ``CSRF_COOKIE_DOMAIN`` ---------------------- Default: ``None`` The domain to be used when setting the CSRF cookie. This can be useful for easily allowing cross-subdomain requests to be excluded from the normal cross site request forgery protection. It should be set to a string such as ``".example.com"`` to allow a POST request from a form on one subdomain to be accepted by a view served from another subdomain. Please note that the presence of this setting does not imply that Django's CSRF protection is safe from cross-subdomain attacks by default - please see the :ref:`CSRF limitations ` section. .. setting:: CSRF_COOKIE_HTTPONLY ``CSRF_COOKIE_HTTPONLY`` ------------------------ Default: ``False`` Whether to use ``HttpOnly`` flag on the CSRF cookie. If this is set to ``True``, client-side JavaScript will not be able to access the CSRF cookie. Designating the CSRF cookie as ``HttpOnly`` doesn't offer any practical protection because CSRF is only to protect against cross-domain attacks. If an attacker can read the cookie via JavaScript, they're already on the same domain as far as the browser knows, so they can do anything they like anyway. (XSS is a much bigger hole than CSRF.) Although the setting offers little practical benefit, it's sometimes required by security auditors. If you enable this and need to send the value of the CSRF token with an AJAX request, your JavaScript must pull the value :ref:`from a hidden CSRF token form input ` instead of :ref:`from the cookie `. See :setting:`SESSION_COOKIE_HTTPONLY` for details on ``HttpOnly``. .. setting:: CSRF_COOKIE_NAME ``CSRF_COOKIE_NAME`` -------------------- Default: ``'csrftoken'`` The name of the cookie to use for the CSRF authentication token. This can be whatever you want (as long as it's different from the other cookie names in your application). See :doc:`/ref/csrf`. .. setting:: CSRF_COOKIE_PATH ``CSRF_COOKIE_PATH`` -------------------- Default: ``'/'`` The path set on the CSRF cookie. This should either match the URL path of your Django installation or be a parent of that path. This is useful if you have multiple Django instances running under the same hostname. They can use different cookie paths, and each instance will only see its own CSRF cookie. .. setting:: CSRF_COOKIE_SAMESITE ``CSRF_COOKIE_SAMESITE`` ------------------------ Default: ``'Lax'`` The value of the `SameSite`_ flag on the CSRF cookie. This flag prevents the cookie from being sent in cross-site requests. See :setting:`SESSION_COOKIE_SAMESITE` for details about ``SameSite``. .. setting:: CSRF_COOKIE_SECURE ``CSRF_COOKIE_SECURE`` ---------------------- Default: ``False`` Whether to use a secure cookie for the CSRF cookie. If this is set to ``True``, the cookie will be marked as "secure", which means browsers may ensure that the cookie is only sent with an HTTPS connection. .. setting:: CSRF_USE_SESSIONS ``CSRF_USE_SESSIONS`` --------------------- Default: ``False`` Whether to store the CSRF token in the user's session instead of in a cookie. It requires the use of :mod:`django.contrib.sessions`. Storing the CSRF token in a cookie (Django's default) is safe, but storing it in the session is common practice in other web frameworks and therefore sometimes demanded by security auditors. Since the :ref:`default error views ` require the CSRF token, :class:`~django.contrib.sessions.middleware.SessionMiddleware` must appear in :setting:`MIDDLEWARE` before any middleware that may raise an exception to trigger an error view (such as :exc:`~django.core.exceptions.PermissionDenied`) if you're using ``CSRF_USE_SESSIONS``. See :ref:`middleware-ordering`. .. setting:: CSRF_FAILURE_VIEW ``CSRF_FAILURE_VIEW`` --------------------- Default: ``'django.views.csrf.csrf_failure'`` A dotted path to the view function to be used when an incoming request is rejected by the :doc:`CSRF protection `. The function should have this signature:: def csrf_failure(request, reason=""): ... where ``reason`` is a short message (intended for developers or logging, not for end users) indicating the reason the request was rejected. It should return an :class:`~django.http.HttpResponseForbidden`. ``django.views.csrf.csrf_failure()`` accepts an additional ``template_name`` parameter that defaults to ``'403_csrf.html'``. If a template with that name exists, it will be used to render the page. .. setting:: CSRF_HEADER_NAME ``CSRF_HEADER_NAME`` -------------------- Default: ``'HTTP_X_CSRFTOKEN'`` The name of the request header used for CSRF authentication. As with other HTTP headers in ``request.META``, the header name received from the server is normalized by converting all characters to uppercase, replacing any hyphens with underscores, and adding an ``'HTTP_'`` prefix to the name. For example, if your client sends a ``'X-XSRF-TOKEN'`` header, the setting should be ``'HTTP_X_XSRF_TOKEN'``. .. setting:: CSRF_TRUSTED_ORIGINS ``CSRF_TRUSTED_ORIGINS`` ------------------------ Default: ``[]`` (Empty list) A list of trusted origins for unsafe requests (e.g. ``POST``). For requests that include the ``Origin`` header, Django's CSRF protection requires that header match the origin present in the ``Host`` header. For a :meth:`secure ` unsafe request that doesn't include the ``Origin`` header, the request must have a ``Referer`` header that matches the origin present in the ``Host`` header. These checks prevent, for example, a ``POST`` request from ``subdomain.example.com`` from succeeding against ``api.example.com``. If you need cross-origin unsafe requests, continuing the example, add ``'https://subdomain.example.com'`` to this list (and/or ``http://...`` if requests originate from an insecure page). The setting also supports subdomains, so you could add ``'https://*.example.com'``, for example, to allow access from all subdomains of ``example.com``. .. versionchanged:: 4.0 The values in older versions must only include the hostname (possibly with a leading dot) and not the scheme or an asterisk. Also, ``Origin`` header checking isn't performed in older versions. .. setting:: DATABASES ``DATABASES`` ------------- Default: ``{}`` (Empty dictionary) A dictionary containing the settings for all databases to be used with Django. It is a nested dictionary whose contents map a database alias to a dictionary containing the options for an individual database. The :setting:`DATABASES` setting must configure a ``default`` database; any number of additional databases may also be specified. The simplest possible settings file is for a single-database setup using SQLite. This can be configured using the following:: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': 'mydatabase', } } When connecting to other database backends, such as MariaDB, MySQL, Oracle, or PostgreSQL, additional connection parameters will be required. See the :setting:`ENGINE ` setting below on how to specify other database types. This example is for PostgreSQL:: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'mydatabase', 'USER': 'mydatabaseuser', 'PASSWORD': 'mypassword', 'HOST': '127.0.0.1', 'PORT': '5432', } } The following inner options that may be required for more complex configurations are available: .. setting:: DATABASE-ATOMIC_REQUESTS ``ATOMIC_REQUESTS`` ~~~~~~~~~~~~~~~~~~~ Default: ``False`` Set this to ``True`` to wrap each view in a transaction on this database. See :ref:`tying-transactions-to-http-requests`. .. setting:: DATABASE-AUTOCOMMIT ``AUTOCOMMIT`` ~~~~~~~~~~~~~~ Default: ``True`` Set this to ``False`` if you want to :ref:`disable Django's transaction management ` and implement your own. .. setting:: DATABASE-ENGINE ``ENGINE`` ~~~~~~~~~~ Default: ``''`` (Empty string) The database backend to use. The built-in database backends are: * ``'django.db.backends.postgresql'`` * ``'django.db.backends.mysql'`` * ``'django.db.backends.sqlite3'`` * ``'django.db.backends.oracle'`` You can use a database backend that doesn't ship with Django by setting ``ENGINE`` to a fully-qualified path (i.e. ``mypackage.backends.whatever``). .. setting:: HOST ``HOST`` ~~~~~~~~ Default: ``''`` (Empty string) Which host to use when connecting to the database. An empty string means localhost. Not used with SQLite. If this value starts with a forward slash (``'/'``) and you're using MySQL, MySQL will connect via a Unix socket to the specified socket. For example:: "HOST": '/var/run/mysql' If you're using MySQL and this value *doesn't* start with a forward slash, then this value is assumed to be the host. If you're using PostgreSQL, by default (empty :setting:`HOST`), the connection to the database is done through UNIX domain sockets ('local' lines in ``pg_hba.conf``). If your UNIX domain socket is not in the standard location, use the same value of ``unix_socket_directory`` from ``postgresql.conf``. If you want to connect through TCP sockets, set :setting:`HOST` to 'localhost' or '127.0.0.1' ('host' lines in ``pg_hba.conf``). On Windows, you should always define :setting:`HOST`, as UNIX domain sockets are not available. .. setting:: NAME ``NAME`` ~~~~~~~~ Default: ``''`` (Empty string) The name of the database to use. For SQLite, it's the full path to the database file. When specifying the path, always use forward slashes, even on Windows (e.g. ``C:/homes/user/mysite/sqlite3.db``). .. setting:: CONN_MAX_AGE ``CONN_MAX_AGE`` ~~~~~~~~~~~~~~~~ Default: ``0`` The lifetime of a database connection, as an integer of seconds. Use ``0`` to close database connections at the end of each request — Django's historical behavior — and ``None`` for unlimited persistent connections. .. setting:: OPTIONS ``OPTIONS`` ~~~~~~~~~~~ Default: ``{}`` (Empty dictionary) Extra parameters to use when connecting to the database. Available parameters vary depending on your database backend. Some information on available parameters can be found in the :doc:`Database Backends ` documentation. For more information, consult your backend module's own documentation. .. setting:: PASSWORD ``PASSWORD`` ~~~~~~~~~~~~ Default: ``''`` (Empty string) The password to use when connecting to the database. Not used with SQLite. .. setting:: PORT ``PORT`` ~~~~~~~~ Default: ``''`` (Empty string) The port to use when connecting to the database. An empty string means the default port. Not used with SQLite. .. setting:: DATABASE-TIME_ZONE ``TIME_ZONE`` ~~~~~~~~~~~~~ Default: ``None`` A string representing the time zone for this database connection or ``None``. This inner option of the :setting:`DATABASES` setting accepts the same values as the general :setting:`TIME_ZONE` setting. When :setting:`USE_TZ` is ``True`` and this option is set, reading datetimes from the database returns aware datetimes in this time zone instead of UTC. When :setting:`USE_TZ` is ``False``, it is an error to set this option. * If the database backend doesn't support time zones (e.g. SQLite, MySQL, Oracle), Django reads and writes datetimes in local time according to this option if it is set and in UTC if it isn't. Changing the connection time zone changes how datetimes are read from and written to the database. * If Django manages the database and you don't have a strong reason to do otherwise, you should leave this option unset. It's best to store datetimes in UTC because it avoids ambiguous or nonexistent datetimes during daylight saving time changes. Also, receiving datetimes in UTC keeps datetime arithmetic simple — there's no need for the ``normalize()`` method provided by pytz. * If you're connecting to a third-party database that stores datetimes in a local time rather than UTC, then you must set this option to the appropriate time zone. Likewise, if Django manages the database but third-party systems connect to the same database and expect to find datetimes in local time, then you must set this option. * If the database backend supports time zones (e.g. PostgreSQL), the ``TIME_ZONE`` option is very rarely needed. It can be changed at any time; the database takes care of converting datetimes to the desired time zone. Setting the time zone of the database connection may be useful for running raw SQL queries involving date/time functions provided by the database, such as ``date_trunc``, because their results depend on the time zone. However, this has a downside: receiving all datetimes in local time makes datetime arithmetic more tricky — you must call the ``normalize()`` method provided by pytz after each operation. Consider converting to local time explicitly with ``AT TIME ZONE`` in raw SQL queries instead of setting the ``TIME_ZONE`` option. .. setting:: DATABASE-DISABLE_SERVER_SIDE_CURSORS ``DISABLE_SERVER_SIDE_CURSORS`` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Default: ``False`` Set this to ``True`` if you want to disable the use of server-side cursors with :meth:`.QuerySet.iterator`. :ref:`transaction-pooling-server-side-cursors` describes the use case. This is a PostgreSQL-specific setting. .. setting:: USER ``USER`` ~~~~~~~~ Default: ``''`` (Empty string) The username to use when connecting to the database. Not used with SQLite. .. setting:: DATABASE-TEST ``TEST`` ~~~~~~~~ Default: ``{}`` (Empty dictionary) A dictionary of settings for test databases; for more details about the creation and use of test databases, see :ref:`the-test-database`. Here's an example with a test database configuration:: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'USER': 'mydatabaseuser', 'NAME': 'mydatabase', 'TEST': { 'NAME': 'mytestdatabase', }, }, } The following keys in the ``TEST`` dictionary are available: .. setting:: TEST_CHARSET ``CHARSET`` ^^^^^^^^^^^ Default: ``None`` The character set encoding used to create the test database. The value of this string is passed directly through to the database, so its format is backend-specific. Supported by the PostgreSQL_ (``postgresql``) and MySQL_ (``mysql``) backends. .. _PostgreSQL: https://www.postgresql.org/docs/current/multibyte.html .. _MySQL: https://dev.mysql.com/doc/refman/en/charset-charsets.html .. setting:: TEST_COLLATION ``COLLATION`` ^^^^^^^^^^^^^ Default: ``None`` The collation order to use when creating the test database. This value is passed directly to the backend, so its format is backend-specific. Only supported for the ``mysql`` backend (see the `MySQL manual`_ for details). .. _MySQL manual: MySQL_ .. setting:: TEST_DEPENDENCIES ``DEPENDENCIES`` ^^^^^^^^^^^^^^^^ Default: ``['default']``, for all databases other than ``default``, which has no dependencies. The creation-order dependencies of the database. See the documentation on :ref:`controlling the creation order of test databases ` for details. .. setting:: TEST_MIGRATE ``MIGRATE`` ^^^^^^^^^^^ Default: ``True`` When set to ``False``, migrations won't run when creating the test database. This is similar to setting ``None`` as a value in :setting:`MIGRATION_MODULES`, but for all apps. .. setting:: TEST_MIRROR ``MIRROR`` ^^^^^^^^^^ Default: ``None`` The alias of the database that this database should mirror during testing. This setting exists to allow for testing of primary/replica (referred to as master/slave by some databases) configurations of multiple databases. See the documentation on :ref:`testing primary/replica configurations ` for details. .. setting:: TEST_NAME ``NAME`` ^^^^^^^^ Default: ``None`` The name of database to use when running the test suite. If the default value (``None``) is used with the SQLite database engine, the tests will use a memory resident database. For all other database engines the test database will use the name ``'test_' + DATABASE_NAME``. See :ref:`the-test-database`. .. setting:: TEST_SERIALIZE ``SERIALIZE`` ^^^^^^^^^^^^^ Boolean value to control whether or not the default test runner serializes the database into an in-memory JSON string before running tests (used to restore the database state between tests if you don't have transactions). You can set this to ``False`` to speed up creation time if you don't have any test classes with :ref:`serialized_rollback=True `. .. deprecated:: 4.0 This setting is deprecated as it can be inferred from the :attr:`~django.test.TestCase.databases` with the :ref:`serialized_rollback ` option enabled. .. setting:: TEST_TEMPLATE ``TEMPLATE`` ^^^^^^^^^^^^ This is a PostgreSQL-specific setting. The name of a `template`_ (e.g. ``'template0'``) from which to create the test database. .. _template: https://www.postgresql.org/docs/current/sql-createdatabase.html .. setting:: TEST_CREATE ``CREATE_DB`` ^^^^^^^^^^^^^ Default: ``True`` This is an Oracle-specific setting. If it is set to ``False``, the test tablespaces won't be automatically created at the beginning of the tests or dropped at the end. .. setting:: TEST_USER_CREATE ``CREATE_USER`` ^^^^^^^^^^^^^^^ Default: ``True`` This is an Oracle-specific setting. If it is set to ``False``, the test user won't be automatically created at the beginning of the tests and dropped at the end. .. setting:: TEST_USER ``USER`` ^^^^^^^^ Default: ``None`` This is an Oracle-specific setting. The username to use when connecting to the Oracle database that will be used when running tests. If not provided, Django will use ``'test_' + USER``. .. setting:: TEST_PASSWD ``PASSWORD`` ^^^^^^^^^^^^ Default: ``None`` This is an Oracle-specific setting. The password to use when connecting to the Oracle database that will be used when running tests. If not provided, Django will generate a random password. .. setting:: TEST_ORACLE_MANAGED_FILES ``ORACLE_MANAGED_FILES`` ^^^^^^^^^^^^^^^^^^^^^^^^ Default: ``False`` This is an Oracle-specific setting. If set to ``True``, Oracle Managed Files (OMF) tablespaces will be used. :setting:`DATAFILE` and :setting:`DATAFILE_TMP` will be ignored. .. setting:: TEST_TBLSPACE ``TBLSPACE`` ^^^^^^^^^^^^ Default: ``None`` This is an Oracle-specific setting. The name of the tablespace that will be used when running tests. If not provided, Django will use ``'test_' + USER``. .. setting:: TEST_TBLSPACE_TMP ``TBLSPACE_TMP`` ^^^^^^^^^^^^^^^^ Default: ``None`` This is an Oracle-specific setting. The name of the temporary tablespace that will be used when running tests. If not provided, Django will use ``'test_' + USER + '_temp'``. .. setting:: DATAFILE ``DATAFILE`` ^^^^^^^^^^^^ Default: ``None`` This is an Oracle-specific setting. The name of the datafile to use for the TBLSPACE. If not provided, Django will use ``TBLSPACE + '.dbf'``. .. setting:: DATAFILE_TMP ``DATAFILE_TMP`` ^^^^^^^^^^^^^^^^ Default: ``None`` This is an Oracle-specific setting. The name of the datafile to use for the TBLSPACE_TMP. If not provided, Django will use ``TBLSPACE_TMP + '.dbf'``. .. setting:: DATAFILE_MAXSIZE ``DATAFILE_MAXSIZE`` ^^^^^^^^^^^^^^^^^^^^ Default: ``'500M'`` This is an Oracle-specific setting. The maximum size that the DATAFILE is allowed to grow to. .. setting:: DATAFILE_TMP_MAXSIZE ``DATAFILE_TMP_MAXSIZE`` ^^^^^^^^^^^^^^^^^^^^^^^^ Default: ``'500M'`` This is an Oracle-specific setting. The maximum size that the DATAFILE_TMP is allowed to grow to. .. setting:: DATAFILE_SIZE ``DATAFILE_SIZE`` ^^^^^^^^^^^^^^^^^ Default: ``'50M'`` This is an Oracle-specific setting. The initial size of the DATAFILE. .. setting:: DATAFILE_TMP_SIZE ``DATAFILE_TMP_SIZE`` ^^^^^^^^^^^^^^^^^^^^^ Default: ``'50M'`` This is an Oracle-specific setting. The initial size of the DATAFILE_TMP. .. setting:: DATAFILE_EXTSIZE ``DATAFILE_EXTSIZE`` ^^^^^^^^^^^^^^^^^^^^ Default: ``'25M'`` This is an Oracle-specific setting. The amount by which the DATAFILE is extended when more space is required. .. setting:: DATAFILE_TMP_EXTSIZE ``DATAFILE_TMP_EXTSIZE`` ^^^^^^^^^^^^^^^^^^^^^^^^ Default: ``'25M'`` This is an Oracle-specific setting. The amount by which the DATAFILE_TMP is extended when more space is required. .. setting:: DATA_UPLOAD_MAX_MEMORY_SIZE ``DATA_UPLOAD_MAX_MEMORY_SIZE`` ------------------------------- Default: ``2621440`` (i.e. 2.5 MB). The maximum size in bytes that a request body may be before a :exc:`~django.core.exceptions.SuspiciousOperation` (``RequestDataTooBig``) is raised. The check is done when accessing ``request.body`` or ``request.POST`` and is calculated against the total request size excluding any file upload data. You can set this to ``None`` to disable the check. Applications that are expected to receive unusually large form posts should tune this setting. The amount of request data is correlated to the amount of memory needed to process the request and populate the GET and POST dictionaries. Large requests could be used as a denial-of-service attack vector if left unchecked. Since web servers don't typically perform deep request inspection, it's not possible to perform a similar check at that level. See also :setting:`FILE_UPLOAD_MAX_MEMORY_SIZE`. .. setting:: DATA_UPLOAD_MAX_NUMBER_FIELDS ``DATA_UPLOAD_MAX_NUMBER_FIELDS`` --------------------------------- Default: ``1000`` The maximum number of parameters that may be received via GET or POST before a :exc:`~django.core.exceptions.SuspiciousOperation` (``TooManyFields``) is raised. You can set this to ``None`` to disable the check. Applications that are expected to receive an unusually large number of form fields should tune this setting. The number of request parameters is correlated to the amount of time needed to process the request and populate the GET and POST dictionaries. Large requests could be used as a denial-of-service attack vector if left unchecked. Since web servers don't typically perform deep request inspection, it's not possible to perform a similar check at that level. .. setting:: DATABASE_ROUTERS ``DATABASE_ROUTERS`` -------------------- Default: ``[]`` (Empty list) The list of routers that will be used to determine which database to use when performing a database query. See the documentation on :ref:`automatic database routing in multi database configurations `. .. setting:: DATE_FORMAT ``DATE_FORMAT`` --------------- Default: ``'N j, Y'`` (e.g. ``Feb. 4, 2003``) The default formatting to use for displaying date fields in any part of the system. Note that if :setting:`USE_L10N` is set to ``True``, then the locale-dictated format has higher precedence and will be applied instead. See :tfilter:`allowed date format strings `. See also :setting:`DATETIME_FORMAT`, :setting:`TIME_FORMAT` and :setting:`SHORT_DATE_FORMAT`. .. setting:: DATE_INPUT_FORMATS ``DATE_INPUT_FORMATS`` ---------------------- Default:: [ '%Y-%m-%d', '%m/%d/%Y', '%m/%d/%y', # '2006-10-25', '10/25/2006', '10/25/06' '%b %d %Y', '%b %d, %Y', # 'Oct 25 2006', 'Oct 25, 2006' '%d %b %Y', '%d %b, %Y', # '25 Oct 2006', '25 Oct, 2006' '%B %d %Y', '%B %d, %Y', # 'October 25 2006', 'October 25, 2006' '%d %B %Y', '%d %B, %Y', # '25 October 2006', '25 October, 2006' ] A list of formats that will be accepted when inputting data on a date field. Formats will be tried in order, using the first valid one. Note that these format strings use Python's :ref:`datetime module syntax `, not the format strings from the :tfilter:`date` template filter. When :setting:`USE_L10N` is ``True``, the locale-dictated format has higher precedence and will be applied instead. See also :setting:`DATETIME_INPUT_FORMATS` and :setting:`TIME_INPUT_FORMATS`. .. setting:: DATETIME_FORMAT ``DATETIME_FORMAT`` ------------------- Default: ``'N j, Y, P'`` (e.g. ``Feb. 4, 2003, 4 p.m.``) The default formatting to use for displaying datetime fields in any part of the system. Note that if :setting:`USE_L10N` is set to ``True``, then the locale-dictated format has higher precedence and will be applied instead. See :tfilter:`allowed date format strings `. See also :setting:`DATE_FORMAT`, :setting:`TIME_FORMAT` and :setting:`SHORT_DATETIME_FORMAT`. .. setting:: DATETIME_INPUT_FORMATS ``DATETIME_INPUT_FORMATS`` -------------------------- Default:: [ '%Y-%m-%d %H:%M:%S', # '2006-10-25 14:30:59' '%Y-%m-%d %H:%M:%S.%f', # '2006-10-25 14:30:59.000200' '%Y-%m-%d %H:%M', # '2006-10-25 14:30' '%m/%d/%Y %H:%M:%S', # '10/25/2006 14:30:59' '%m/%d/%Y %H:%M:%S.%f', # '10/25/2006 14:30:59.000200' '%m/%d/%Y %H:%M', # '10/25/2006 14:30' '%m/%d/%y %H:%M:%S', # '10/25/06 14:30:59' '%m/%d/%y %H:%M:%S.%f', # '10/25/06 14:30:59.000200' '%m/%d/%y %H:%M', # '10/25/06 14:30' ] A list of formats that will be accepted when inputting data on a datetime field. Formats will be tried in order, using the first valid one. Note that these format strings use Python's :ref:`datetime module syntax `, not the format strings from the :tfilter:`date` template filter. Date-only formats are not included as datetime fields will automatically try :setting:`DATE_INPUT_FORMATS` in last resort. When :setting:`USE_L10N` is ``True``, the locale-dictated format has higher precedence and will be applied instead. See also :setting:`DATE_INPUT_FORMATS` and :setting:`TIME_INPUT_FORMATS`. .. setting:: DEBUG ``DEBUG`` --------- Default: ``False`` A boolean that turns on/off debug mode. Never deploy a site into production with :setting:`DEBUG` turned on. One of the main features of debug mode is the display of detailed error pages. If your app raises an exception when :setting:`DEBUG` is ``True``, Django will display a detailed traceback, including a lot of metadata about your environment, such as all the currently defined Django settings (from ``settings.py``). As a security measure, Django will *not* include settings that might be sensitive, such as :setting:`SECRET_KEY`. Specifically, it will exclude any setting whose name includes any of the following: * ``'API'`` * ``'KEY'`` * ``'PASS'`` * ``'SECRET'`` * ``'SIGNATURE'`` * ``'TOKEN'`` Note that these are *partial* matches. ``'PASS'`` will also match PASSWORD, just as ``'TOKEN'`` will also match TOKENIZED and so on. Still, note that there are always going to be sections of your debug output that are inappropriate for public consumption. File paths, configuration options and the like all give attackers extra information about your server. It is also important to remember that when running with :setting:`DEBUG` turned on, Django will remember every SQL query it executes. This is useful when you're debugging, but it'll rapidly consume memory on a production server. Finally, if :setting:`DEBUG` is ``False``, you also need to properly set the :setting:`ALLOWED_HOSTS` setting. Failing to do so will result in all requests being returned as "Bad Request (400)". .. note:: The default :file:`settings.py` file created by :djadmin:`django-admin startproject ` sets ``DEBUG = True`` for convenience. .. setting:: DEBUG_PROPAGATE_EXCEPTIONS ``DEBUG_PROPAGATE_EXCEPTIONS`` ------------------------------ Default: ``False`` If set to ``True``, Django's exception handling of view functions (:data:`~django.conf.urls.handler500`, or the debug view if :setting:`DEBUG` is ``True``) and logging of 500 responses (:ref:`django-request-logger`) is skipped and exceptions propagate upwards. This can be useful for some test setups. It shouldn't be used on a live site unless you want your web server (instead of Django) to generate "Internal Server Error" responses. In that case, make sure your server doesn't show the stack trace or other sensitive information in the response. .. setting:: DECIMAL_SEPARATOR ``DECIMAL_SEPARATOR`` --------------------- Default: ``'.'`` (Dot) Default decimal separator used when formatting decimal numbers. Note that if :setting:`USE_L10N` is set to ``True``, then the locale-dictated format has higher precedence and will be applied instead. See also :setting:`NUMBER_GROUPING`, :setting:`THOUSAND_SEPARATOR` and :setting:`USE_THOUSAND_SEPARATOR`. .. setting:: DEFAULT_AUTO_FIELD ``DEFAULT_AUTO_FIELD`` ---------------------- .. versionadded:: 3.2 Default: ``'``:class:`django.db.models.AutoField`\ ``'`` Default primary key field type to use for models that don't have a field with :attr:`primary_key=True `. .. admonition:: Migrating auto-created through tables The value of ``DEFAULT_AUTO_FIELD`` will be respected when creating new auto-created through tables for many-to-many relationships. Unfortunately, the primary keys of existing auto-created through tables cannot currently be updated by the migrations framework. This means that if you switch the value of ``DEFAULT_AUTO_FIELD`` and then generate migrations, the primary keys of the related models will be updated, as will the foreign keys from the through table, but the primary key of the auto-created through table will not be migrated. In order to address this, you should add a :class:`~django.db.migrations.operations.RunSQL` operation to your migrations to perform the required ``ALTER TABLE`` step. You can check the existing table name through ``sqlmigrate``, ``dbshell``, or with the field’s ``remote_field.through._meta.db_table`` property. Explicitly defined through models are already handled by the migrations system. Allowing automatic migrations for the primary key of existing auto-created through tables :ticket:`may be implemented at a later date <32674>`. .. setting:: DEFAULT_CHARSET ``DEFAULT_CHARSET`` ------------------- Default: ``'utf-8'`` Default charset to use for all ``HttpResponse`` objects, if a MIME type isn't manually specified. Used when constructing the ``Content-Type`` header. .. setting:: DEFAULT_EXCEPTION_REPORTER ``DEFAULT_EXCEPTION_REPORTER`` ------------------------------ Default: ``'``:class:`django.views.debug.ExceptionReporter`\ ``'`` Default exception reporter class to be used if none has been assigned to the :class:`~django.http.HttpRequest` instance yet. See :ref:`custom-error-reports`. .. setting:: DEFAULT_EXCEPTION_REPORTER_FILTER ``DEFAULT_EXCEPTION_REPORTER_FILTER`` ------------------------------------- Default: ``'``:class:`django.views.debug.SafeExceptionReporterFilter`\ ``'`` Default exception reporter filter class to be used if none has been assigned to the :class:`~django.http.HttpRequest` instance yet. See :ref:`Filtering error reports`. .. setting:: DEFAULT_FILE_STORAGE ``DEFAULT_FILE_STORAGE`` ------------------------ Default: ``'``:class:`django.core.files.storage.FileSystemStorage`\ ``'`` Default file storage class to be used for any file-related operations that don't specify a particular storage system. See :doc:`/topics/files`. .. setting:: DEFAULT_FROM_EMAIL ``DEFAULT_FROM_EMAIL`` ---------------------- Default: ``'webmaster@localhost'`` Default email address to use for various automated correspondence from the site manager(s). This doesn't include error messages sent to :setting:`ADMINS` and :setting:`MANAGERS`; for that, see :setting:`SERVER_EMAIL`. .. setting:: DEFAULT_INDEX_TABLESPACE ``DEFAULT_INDEX_TABLESPACE`` ---------------------------- Default: ``''`` (Empty string) Default tablespace to use for indexes on fields that don't specify one, if the backend supports it (see :doc:`/topics/db/tablespaces`). .. setting:: DEFAULT_TABLESPACE ``DEFAULT_TABLESPACE`` ---------------------- Default: ``''`` (Empty string) Default tablespace to use for models that don't specify one, if the backend supports it (see :doc:`/topics/db/tablespaces`). .. setting:: DISALLOWED_USER_AGENTS ``DISALLOWED_USER_AGENTS`` -------------------------- Default: ``[]`` (Empty list) List of compiled regular expression objects representing User-Agent strings that are not allowed to visit any page, systemwide. Use this for bots/crawlers. This is only used if ``CommonMiddleware`` is installed (see :doc:`/topics/http/middleware`). .. setting:: EMAIL_BACKEND ``EMAIL_BACKEND`` ----------------- Default: ``'``:class:`django.core.mail.backends.smtp.EmailBackend`\ ``'`` The backend to use for sending emails. For the list of available backends see :doc:`/topics/email`. .. setting:: EMAIL_FILE_PATH ``EMAIL_FILE_PATH`` ------------------- Default: Not defined The directory used by the :ref:`file email backend ` to store output files. .. setting:: EMAIL_HOST ``EMAIL_HOST`` -------------- Default: ``'localhost'`` The host to use for sending email. See also :setting:`EMAIL_PORT`. .. setting:: EMAIL_HOST_PASSWORD ``EMAIL_HOST_PASSWORD`` ----------------------- Default: ``''`` (Empty string) Password to use for the SMTP server defined in :setting:`EMAIL_HOST`. This setting is used in conjunction with :setting:`EMAIL_HOST_USER` when authenticating to the SMTP server. If either of these settings is empty, Django won't attempt authentication. See also :setting:`EMAIL_HOST_USER`. .. setting:: EMAIL_HOST_USER ``EMAIL_HOST_USER`` ------------------- Default: ``''`` (Empty string) Username to use for the SMTP server defined in :setting:`EMAIL_HOST`. If empty, Django won't attempt authentication. See also :setting:`EMAIL_HOST_PASSWORD`. .. setting:: EMAIL_PORT ``EMAIL_PORT`` -------------- Default: ``25`` Port to use for the SMTP server defined in :setting:`EMAIL_HOST`. .. setting:: EMAIL_SUBJECT_PREFIX ``EMAIL_SUBJECT_PREFIX`` ------------------------ Default: ``'[Django] '`` Subject-line prefix for email messages sent with ``django.core.mail.mail_admins`` or ``django.core.mail.mail_managers``. You'll probably want to include the trailing space. .. setting:: EMAIL_USE_LOCALTIME ``EMAIL_USE_LOCALTIME`` ----------------------- Default: ``False`` Whether to send the SMTP ``Date`` header of email messages in the local time zone (``True``) or in UTC (``False``). .. setting:: EMAIL_USE_TLS ``EMAIL_USE_TLS`` ----------------- Default: ``False`` Whether to use a TLS (secure) connection when talking to the SMTP server. This is used for explicit TLS connections, generally on port 587. If you are experiencing hanging connections, see the implicit TLS setting :setting:`EMAIL_USE_SSL`. .. setting:: EMAIL_USE_SSL ``EMAIL_USE_SSL`` ----------------- Default: ``False`` Whether to use an implicit TLS (secure) connection when talking to the SMTP server. In most email documentation this type of TLS connection is referred to as SSL. It is generally used on port 465. If you are experiencing problems, see the explicit TLS setting :setting:`EMAIL_USE_TLS`. Note that :setting:`EMAIL_USE_TLS`/:setting:`EMAIL_USE_SSL` are mutually exclusive, so only set one of those settings to ``True``. .. setting:: EMAIL_SSL_CERTFILE ``EMAIL_SSL_CERTFILE`` ---------------------- Default: ``None`` If :setting:`EMAIL_USE_SSL` or :setting:`EMAIL_USE_TLS` is ``True``, you can optionally specify the path to a PEM-formatted certificate chain file to use for the SSL connection. .. setting:: EMAIL_SSL_KEYFILE ``EMAIL_SSL_KEYFILE`` --------------------- Default: ``None`` If :setting:`EMAIL_USE_SSL` or :setting:`EMAIL_USE_TLS` is ``True``, you can optionally specify the path to a PEM-formatted private key file to use for the SSL connection. Note that setting :setting:`EMAIL_SSL_CERTFILE` and :setting:`EMAIL_SSL_KEYFILE` doesn't result in any certificate checking. They're passed to the underlying SSL connection. Please refer to the documentation of Python's :func:`python:ssl.wrap_socket` function for details on how the certificate chain file and private key file are handled. .. setting:: EMAIL_TIMEOUT ``EMAIL_TIMEOUT`` ----------------- Default: ``None`` Specifies a timeout in seconds for blocking operations like the connection attempt. .. setting:: FILE_UPLOAD_HANDLERS ``FILE_UPLOAD_HANDLERS`` ------------------------ Default:: [ 'django.core.files.uploadhandler.MemoryFileUploadHandler', 'django.core.files.uploadhandler.TemporaryFileUploadHandler', ] A list of handlers to use for uploading. Changing this setting allows complete customization -- even replacement -- of Django's upload process. See :doc:`/topics/files` for details. .. setting:: FILE_UPLOAD_MAX_MEMORY_SIZE ``FILE_UPLOAD_MAX_MEMORY_SIZE`` ------------------------------- Default: ``2621440`` (i.e. 2.5 MB). The maximum size (in bytes) that an upload will be before it gets streamed to the file system. See :doc:`/topics/files` for details. See also :setting:`DATA_UPLOAD_MAX_MEMORY_SIZE`. .. setting:: FILE_UPLOAD_DIRECTORY_PERMISSIONS ``FILE_UPLOAD_DIRECTORY_PERMISSIONS`` ------------------------------------- Default: ``None`` The numeric mode to apply to directories created in the process of uploading files. This setting also determines the default permissions for collected static directories when using the :djadmin:`collectstatic` management command. See :djadmin:`collectstatic` for details on overriding it. This value mirrors the functionality and caveats of the :setting:`FILE_UPLOAD_PERMISSIONS` setting. .. setting:: FILE_UPLOAD_PERMISSIONS ``FILE_UPLOAD_PERMISSIONS`` --------------------------- Default: ``0o644`` The numeric mode (i.e. ``0o644``) to set newly uploaded files to. For more information about what these modes mean, see the documentation for :func:`os.chmod`. If ``None``, you'll get operating-system dependent behavior. On most platforms, temporary files will have a mode of ``0o600``, and files saved from memory will be saved using the system's standard umask. For security reasons, these permissions aren't applied to the temporary files that are stored in :setting:`FILE_UPLOAD_TEMP_DIR`. This setting also determines the default permissions for collected static files when using the :djadmin:`collectstatic` management command. See :djadmin:`collectstatic` for details on overriding it. .. warning:: **Always prefix the mode with** ``0o`` **.** If you're not familiar with file modes, please note that the ``0o`` prefix is very important: it indicates an octal number, which is the way that modes must be specified. If you try to use ``644``, you'll get totally incorrect behavior. .. setting:: FILE_UPLOAD_TEMP_DIR ``FILE_UPLOAD_TEMP_DIR`` ------------------------ Default: ``None`` The directory to store data to (typically files larger than :setting:`FILE_UPLOAD_MAX_MEMORY_SIZE`) temporarily while uploading files. If ``None``, Django will use the standard temporary directory for the operating system. For example, this will default to ``/tmp`` on \*nix-style operating systems. See :doc:`/topics/files` for details. .. setting:: FIRST_DAY_OF_WEEK ``FIRST_DAY_OF_WEEK`` --------------------- Default: ``0`` (Sunday) A number representing the first day of the week. This is especially useful when displaying a calendar. This value is only used when not using format internationalization, or when a format cannot be found for the current locale. The value must be an integer from 0 to 6, where 0 means Sunday, 1 means Monday and so on. .. setting:: FIXTURE_DIRS ``FIXTURE_DIRS`` ---------------- Default: ``[]`` (Empty list) List of directories searched for fixture files, in addition to the ``fixtures`` directory of each application, in search order. Note that these paths should use Unix-style forward slashes, even on Windows. See :ref:`initial-data-via-fixtures` and :ref:`topics-testing-fixtures`. .. setting:: FORCE_SCRIPT_NAME ``FORCE_SCRIPT_NAME`` --------------------- Default: ``None`` If not ``None``, this will be used as the value of the ``SCRIPT_NAME`` environment variable in any HTTP request. This setting can be used to override the server-provided value of ``SCRIPT_NAME``, which may be a rewritten version of the preferred value or not supplied at all. It is also used by :func:`django.setup()` to set the URL resolver script prefix outside of the request/response cycle (e.g. in management commands and standalone scripts) to generate correct URLs when ``SCRIPT_NAME`` is not ``/``. .. setting:: FORM_RENDERER ``FORM_RENDERER`` ----------------- Default: ``'``:class:`django.forms.renderers.DjangoTemplates`\ ``'`` The class that renders form widgets. It must implement :ref:`the low-level render API `. .. setting:: FORMAT_MODULE_PATH ``FORMAT_MODULE_PATH`` ---------------------- Default: ``None`` A full Python path to a Python package that contains custom format definitions for project locales. If not ``None``, Django will check for a ``formats.py`` file, under the directory named as the current locale, and will use the formats defined in this file. For example, if :setting:`FORMAT_MODULE_PATH` is set to ``mysite.formats``, and current language is ``en`` (English), Django will expect a directory tree like:: mysite/ formats/ __init__.py en/ __init__.py formats.py You can also set this setting to a list of Python paths, for example:: FORMAT_MODULE_PATH = [ 'mysite.formats', 'some_app.formats', ] When Django searches for a certain format, it will go through all given Python paths until it finds a module that actually defines the given format. This means that formats defined in packages farther up in the list will take precedence over the same formats in packages farther down. Available formats are: * :setting:`DATE_FORMAT` * :setting:`DATE_INPUT_FORMATS` * :setting:`DATETIME_FORMAT`, * :setting:`DATETIME_INPUT_FORMATS` * :setting:`DECIMAL_SEPARATOR` * :setting:`FIRST_DAY_OF_WEEK` * :setting:`MONTH_DAY_FORMAT` * :setting:`NUMBER_GROUPING` * :setting:`SHORT_DATE_FORMAT` * :setting:`SHORT_DATETIME_FORMAT` * :setting:`THOUSAND_SEPARATOR` * :setting:`TIME_FORMAT` * :setting:`TIME_INPUT_FORMATS` * :setting:`YEAR_MONTH_FORMAT` .. setting:: IGNORABLE_404_URLS ``IGNORABLE_404_URLS`` ---------------------- Default: ``[]`` (Empty list) List of compiled regular expression objects describing URLs that should be ignored when reporting HTTP 404 errors via email (see :doc:`/howto/error-reporting`). Regular expressions are matched against :meth:`request's full paths ` (including query string, if any). Use this if your site does not provide a commonly requested file such as ``favicon.ico`` or ``robots.txt``. This is only used if :class:`~django.middleware.common.BrokenLinkEmailsMiddleware` is enabled (see :doc:`/topics/http/middleware`). .. setting:: INSTALLED_APPS ``INSTALLED_APPS`` ------------------ Default: ``[]`` (Empty list) A list of strings designating all applications that are enabled in this Django installation. Each string should be a dotted Python path to: * an application configuration class (preferred), or * a package containing an application. :doc:`Learn more about application configurations `. .. admonition:: Use the application registry for introspection Your code should never access :setting:`INSTALLED_APPS` directly. Use :attr:`django.apps.apps` instead. .. admonition:: Application names and labels must be unique in :setting:`INSTALLED_APPS` Application :attr:`names ` — the dotted Python path to the application package — must be unique. There is no way to include the same application twice, short of duplicating its code under another name. Application :attr:`labels ` — by default the final part of the name — must be unique too. For example, you can't include both ``django.contrib.auth`` and ``myproject.auth``. However, you can relabel an application with a custom configuration that defines a different :attr:`~django.apps.AppConfig.label`. These rules apply regardless of whether :setting:`INSTALLED_APPS` references application configuration classes or application packages. When several applications provide different versions of the same resource (template, static file, management command, translation), the application listed first in :setting:`INSTALLED_APPS` has precedence. .. setting:: INTERNAL_IPS ``INTERNAL_IPS`` ---------------- Default: ``[]`` (Empty list) A list of IP addresses, as strings, that: * Allow the :func:`~django.template.context_processors.debug` context processor to add some variables to the template context. * Can use the :ref:`admindocs bookmarklets ` even if not logged in as a staff user. * Are marked as "internal" (as opposed to "EXTERNAL") in :class:`~django.utils.log.AdminEmailHandler` emails. .. setting:: LANGUAGE_CODE ``LANGUAGE_CODE`` ----------------- Default: ``'en-us'`` A string representing the language code for this installation. This should be in standard :term:`language ID format `. For example, U.S. English is ``"en-us"``. See also the `list of language identifiers`_ and :doc:`/topics/i18n/index`. :setting:`USE_I18N` must be active for this setting to have any effect. It serves two purposes: * If the locale middleware isn't in use, it decides which translation is served to all users. * If the locale middleware is active, it provides a fallback language in case the user's preferred language can't be determined or is not supported by the website. It also provides the fallback translation when a translation for a given literal doesn't exist for the user's preferred language. See :ref:`how-django-discovers-language-preference` for more details. .. _list of language identifiers: http://www.i18nguy.com/unicode/language-identifiers.html .. setting:: LANGUAGE_COOKIE_AGE ``LANGUAGE_COOKIE_AGE`` ----------------------- Default: ``None`` (expires at browser close) The age of the language cookie, in seconds. .. setting:: LANGUAGE_COOKIE_DOMAIN ``LANGUAGE_COOKIE_DOMAIN`` -------------------------- Default: ``None`` The domain to use for the language cookie. Set this to a string such as ``"example.com"`` for cross-domain cookies, or use ``None`` for a standard domain cookie. Be cautious when updating this setting on a production site. If you update this setting to enable cross-domain cookies on a site that previously used standard domain cookies, existing user cookies that have the old domain will not be updated. This will result in site users being unable to switch the language as long as these cookies persist. The only safe and reliable option to perform the switch is to change the language cookie name permanently (via the :setting:`LANGUAGE_COOKIE_NAME` setting) and to add a middleware that copies the value from the old cookie to a new one and then deletes the old one. .. setting:: LANGUAGE_COOKIE_HTTPONLY ``LANGUAGE_COOKIE_HTTPONLY`` ---------------------------- Default: ``False`` Whether to use ``HttpOnly`` flag on the language cookie. If this is set to ``True``, client-side JavaScript will not be able to access the language cookie. See :setting:`SESSION_COOKIE_HTTPONLY` for details on ``HttpOnly``. .. setting:: LANGUAGE_COOKIE_NAME ``LANGUAGE_COOKIE_NAME`` ------------------------ Default: ``'django_language'`` The name of the cookie to use for the language cookie. This can be whatever you want (as long as it's different from the other cookie names in your application). See :doc:`/topics/i18n/index`. .. setting:: LANGUAGE_COOKIE_PATH ``LANGUAGE_COOKIE_PATH`` ------------------------ Default: ``'/'`` The path set on the language cookie. This should either match the URL path of your Django installation or be a parent of that path. This is useful if you have multiple Django instances running under the same hostname. They can use different cookie paths and each instance will only see its own language cookie. Be cautious when updating this setting on a production site. If you update this setting to use a deeper path than it previously used, existing user cookies that have the old path will not be updated. This will result in site users being unable to switch the language as long as these cookies persist. The only safe and reliable option to perform the switch is to change the language cookie name permanently (via the :setting:`LANGUAGE_COOKIE_NAME` setting), and to add a middleware that copies the value from the old cookie to a new one and then deletes the one. .. setting:: LANGUAGE_COOKIE_SAMESITE ``LANGUAGE_COOKIE_SAMESITE`` ---------------------------- Default: ``None`` The value of the `SameSite`_ flag on the language cookie. This flag prevents the cookie from being sent in cross-site requests. See :setting:`SESSION_COOKIE_SAMESITE` for details about ``SameSite``. .. setting:: LANGUAGE_COOKIE_SECURE ``LANGUAGE_COOKIE_SECURE`` -------------------------- Default: ``False`` Whether to use a secure cookie for the language cookie. If this is set to ``True``, the cookie will be marked as "secure", which means browsers may ensure that the cookie is only sent under an HTTPS connection. .. setting:: LANGUAGES ``LANGUAGES`` ------------- Default: A list of all available languages. This list is continually growing and including a copy here would inevitably become rapidly out of date. You can see the current list of translated languages by looking in :source:`django/conf/global_settings.py`. The list is a list of two-tuples in the format (:term:`language code`, ``language name``) -- for example, ``('ja', 'Japanese')``. This specifies which languages are available for language selection. See :doc:`/topics/i18n/index`. Generally, the default value should suffice. Only set this setting if you want to restrict language selection to a subset of the Django-provided languages. If you define a custom :setting:`LANGUAGES` setting, you can mark the language names as translation strings using the :func:`~django.utils.translation.gettext_lazy` function. Here's a sample settings file:: from django.utils.translation import gettext_lazy as _ LANGUAGES = [ ('de', _('German')), ('en', _('English')), ] .. setting:: LANGUAGES_BIDI ``LANGUAGES_BIDI`` ------------------ Default: A list of all language codes that are written right-to-left. You can see the current list of these languages by looking in :source:`django/conf/global_settings.py`. The list contains :term:`language codes` for languages that are written right-to-left. Generally, the default value should suffice. Only set this setting if you want to restrict language selection to a subset of the Django-provided languages. If you define a custom :setting:`LANGUAGES` setting, the list of bidirectional languages may contain language codes which are not enabled on a given site. .. setting:: LOCALE_PATHS ``LOCALE_PATHS`` ---------------- Default: ``[]`` (Empty list) A list of directories where Django looks for translation files. See :ref:`how-django-discovers-translations`. Example:: LOCALE_PATHS = [ '/home/www/project/common_files/locale', '/var/local/translations/locale', ] Django will look within each of these paths for the ``/LC_MESSAGES`` directories containing the actual translation files. .. setting:: LOGGING ``LOGGING`` ----------- Default: A logging configuration dictionary. A data structure containing configuration information. The contents of this data structure will be passed as the argument to the configuration method described in :setting:`LOGGING_CONFIG`. Among other things, the default logging configuration passes HTTP 500 server errors to an email log handler when :setting:`DEBUG` is ``False``. See also :ref:`configuring-logging`. You can see the default logging configuration by looking in :source:`django/utils/log.py`. .. setting:: LOGGING_CONFIG ``LOGGING_CONFIG`` ------------------ Default: ``'logging.config.dictConfig'`` A path to a callable that will be used to configure logging in the Django project. Points at an instance of Python's :ref:`dictConfig ` configuration method by default. If you set :setting:`LOGGING_CONFIG` to ``None``, the logging configuration process will be skipped. .. setting:: MANAGERS ``MANAGERS`` ------------ Default: ``[]`` (Empty list) A list in the same format as :setting:`ADMINS` that specifies who should get broken link notifications when :class:`~django.middleware.common.BrokenLinkEmailsMiddleware` is enabled. .. setting:: MEDIA_ROOT ``MEDIA_ROOT`` -------------- Default: ``''`` (Empty string) Absolute filesystem path to the directory that will hold :doc:`user-uploaded files `. Example: ``"/var/www/example.com/media/"`` See also :setting:`MEDIA_URL`. .. warning:: :setting:`MEDIA_ROOT` and :setting:`STATIC_ROOT` must have different values. Before :setting:`STATIC_ROOT` was introduced, it was common to rely or fallback on :setting:`MEDIA_ROOT` to also serve static files; however, since this can have serious security implications, there is a validation check to prevent it. .. setting:: MEDIA_URL ``MEDIA_URL`` ------------- Default: ``''`` (Empty string) URL that handles the media served from :setting:`MEDIA_ROOT`, used for :doc:`managing stored files `. It must end in a slash if set to a non-empty value. You will need to :ref:`configure these files to be served ` in both development and production environments. If you want to use ``{{ MEDIA_URL }}`` in your templates, add ``'django.template.context_processors.media'`` in the ``'context_processors'`` option of :setting:`TEMPLATES`. Example: ``"http://media.example.com/"`` .. warning:: There are security risks if you are accepting uploaded content from untrusted users! See the security guide's topic on :ref:`user-uploaded-content-security` for mitigation details. .. warning:: :setting:`MEDIA_URL` and :setting:`STATIC_URL` must have different values. See :setting:`MEDIA_ROOT` for more details. .. note:: If :setting:`MEDIA_URL` is a relative path, then it will be prefixed by the server-provided value of ``SCRIPT_NAME`` (or ``/`` if not set). This makes it easier to serve a Django application in a subpath without adding an extra configuration to the settings. .. setting:: MIDDLEWARE ``MIDDLEWARE`` -------------- Default: ``None`` A list of middleware to use. See :doc:`/topics/http/middleware`. .. setting:: MIGRATION_MODULES ``MIGRATION_MODULES`` --------------------- Default: ``{}`` (Empty dictionary) A dictionary specifying the package where migration modules can be found on a per-app basis. The default value of this setting is an empty dictionary, but the default package name for migration modules is ``migrations``. Example:: {'blog': 'blog.db_migrations'} In this case, migrations pertaining to the ``blog`` app will be contained in the ``blog.db_migrations`` package. If you provide the ``app_label`` argument, :djadmin:`makemigrations` will automatically create the package if it doesn't already exist. When you supply ``None`` as a value for an app, Django will consider the app as an app without migrations regardless of an existing ``migrations`` submodule. This can be used, for example, in a test settings file to skip migrations while testing (tables will still be created for the apps' models). To disable migrations for all apps during tests, you can set the :setting:`MIGRATE ` to ``False`` instead. If ``MIGRATION_MODULES`` is used in your general project settings, remember to use the :option:`migrate --run-syncdb` option if you want to create tables for the app. .. setting:: MONTH_DAY_FORMAT ``MONTH_DAY_FORMAT`` -------------------- Default: ``'F j'`` The default formatting to use for date fields on Django admin change-list pages -- and, possibly, by other parts of the system -- in cases when only the month and day are displayed. For example, when a Django admin change-list page is being filtered by a date drilldown, the header for a given day displays the day and month. Different locales have different formats. For example, U.S. English would say "January 1," whereas Spanish might say "1 Enero." Note that if :setting:`USE_L10N` is set to ``True``, then the corresponding locale-dictated format has higher precedence and will be applied. See :tfilter:`allowed date format strings `. See also :setting:`DATE_FORMAT`, :setting:`DATETIME_FORMAT`, :setting:`TIME_FORMAT` and :setting:`YEAR_MONTH_FORMAT`. .. setting:: NUMBER_GROUPING ``NUMBER_GROUPING`` ------------------- Default: ``0`` Number of digits grouped together on the integer part of a number. Common use is to display a thousand separator. If this setting is ``0``, then no grouping will be applied to the number. If this setting is greater than ``0``, then :setting:`THOUSAND_SEPARATOR` will be used as the separator between those groups. Some locales use non-uniform digit grouping, e.g. ``10,00,00,000`` in ``en_IN``. For this case, you can provide a sequence with the number of digit group sizes to be applied. The first number defines the size of the group preceding the decimal delimiter, and each number that follows defines the size of preceding groups. If the sequence is terminated with ``-1``, no further grouping is performed. If the sequence terminates with a ``0``, the last group size is used for the remainder of the number. Example tuple for ``en_IN``:: NUMBER_GROUPING = (3, 2, 0) Note that if :setting:`USE_L10N` is set to ``True``, then the locale-dictated format has higher precedence and will be applied instead. See also :setting:`DECIMAL_SEPARATOR`, :setting:`THOUSAND_SEPARATOR` and :setting:`USE_THOUSAND_SEPARATOR`. .. setting:: PREPEND_WWW ``PREPEND_WWW`` --------------- Default: ``False`` Whether to prepend the "www." subdomain to URLs that don't have it. This is only used if :class:`~django.middleware.common.CommonMiddleware` is installed (see :doc:`/topics/http/middleware`). See also :setting:`APPEND_SLASH`. .. setting:: ROOT_URLCONF ``ROOT_URLCONF`` ---------------- Default: Not defined A string representing the full Python import path to your root URLconf, for example ``"mydjangoapps.urls"``. Can be overridden on a per-request basis by setting the attribute ``urlconf`` on the incoming ``HttpRequest`` object. See :ref:`how-django-processes-a-request` for details. .. setting:: SECRET_KEY ``SECRET_KEY`` -------------- Default: ``''`` (Empty string) A secret key for a particular Django installation. This is used to provide :doc:`cryptographic signing `, and should be set to a unique, unpredictable value. :djadmin:`django-admin startproject ` automatically adds a randomly-generated ``SECRET_KEY`` to each new project. Uses of the key shouldn't assume that it's text or bytes. Every use should go through :func:`~django.utils.encoding.force_str` or :func:`~django.utils.encoding.force_bytes` to convert it to the desired type. Django will refuse to start if :setting:`SECRET_KEY` is not set. .. warning:: **Keep this value secret.** Running Django with a known :setting:`SECRET_KEY` defeats many of Django's security protections, and can lead to privilege escalation and remote code execution vulnerabilities. The secret key is used for: * All :doc:`sessions ` if you are using any other session backend than ``django.contrib.sessions.backends.cache``, or are using the default :meth:`~django.contrib.auth.models.AbstractBaseUser.get_session_auth_hash()`. * All :doc:`messages ` if you are using :class:`~django.contrib.messages.storage.cookie.CookieStorage` or :class:`~django.contrib.messages.storage.fallback.FallbackStorage`. * All :class:`~django.contrib.auth.views.PasswordResetView` tokens. * Any usage of :doc:`cryptographic signing `, unless a different key is provided. If you rotate your secret key, all of the above will be invalidated. Secret keys are not used for passwords of users and key rotation will not affect them. .. note:: The default :file:`settings.py` file created by :djadmin:`django-admin startproject ` creates a unique ``SECRET_KEY`` for convenience. .. setting:: SECURE_CONTENT_TYPE_NOSNIFF ``SECURE_CONTENT_TYPE_NOSNIFF`` ------------------------------- Default: ``True`` If ``True``, the :class:`~django.middleware.security.SecurityMiddleware` sets the :ref:`x-content-type-options` header on all responses that do not already have it. .. setting:: SECURE_CROSS_ORIGIN_OPENER_POLICY ``SECURE_CROSS_ORIGIN_OPENER_POLICY`` ------------------------------------- .. versionadded:: 4.0 Default: ``'same-origin'`` Unless set to ``None``, the :class:`~django.middleware.security.SecurityMiddleware` sets the :ref:`cross-origin-opener-policy` header on all responses that do not already have it to the value provided. .. setting:: SECURE_HSTS_INCLUDE_SUBDOMAINS ``SECURE_HSTS_INCLUDE_SUBDOMAINS`` ---------------------------------- Default: ``False`` If ``True``, the :class:`~django.middleware.security.SecurityMiddleware` adds the ``includeSubDomains`` directive to the :ref:`http-strict-transport-security` header. It has no effect unless :setting:`SECURE_HSTS_SECONDS` is set to a non-zero value. .. warning:: Setting this incorrectly can irreversibly (for the value of :setting:`SECURE_HSTS_SECONDS`) break your site. Read the :ref:`http-strict-transport-security` documentation first. .. setting:: SECURE_HSTS_PRELOAD ``SECURE_HSTS_PRELOAD`` ----------------------- Default: ``False`` If ``True``, the :class:`~django.middleware.security.SecurityMiddleware` adds the ``preload`` directive to the :ref:`http-strict-transport-security` header. It has no effect unless :setting:`SECURE_HSTS_SECONDS` is set to a non-zero value. .. setting:: SECURE_HSTS_SECONDS ``SECURE_HSTS_SECONDS`` ----------------------- Default: ``0`` If set to a non-zero integer value, the :class:`~django.middleware.security.SecurityMiddleware` sets the :ref:`http-strict-transport-security` header on all responses that do not already have it. .. warning:: Setting this incorrectly can irreversibly (for some time) break your site. Read the :ref:`http-strict-transport-security` documentation first. .. setting:: SECURE_PROXY_SSL_HEADER ``SECURE_PROXY_SSL_HEADER`` --------------------------- Default: ``None`` A tuple representing a HTTP header/value combination that signifies a request is secure. This controls the behavior of the request object's ``is_secure()`` method. By default, ``is_secure()`` determines if a request is secure by confirming that a requested URL uses ``https://``. This method is important for Django's CSRF protection, and it may be used by your own code or third-party apps. If your Django app is behind a proxy, though, the proxy may be "swallowing" whether the original request uses HTTPS or not. If there is a non-HTTPS connection between the proxy and Django then ``is_secure()`` would always return ``False`` -- even for requests that were made via HTTPS by the end user. In contrast, if there is an HTTPS connection between the proxy and Django then ``is_secure()`` would always return ``True`` -- even for requests that were made originally via HTTP. In this situation, configure your proxy to set a custom HTTP header that tells Django whether the request came in via HTTPS, and set ``SECURE_PROXY_SSL_HEADER`` so that Django knows what header to look for. Set a tuple with two elements -- the name of the header to look for and the required value. For example:: SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') This tells Django to trust the ``X-Forwarded-Proto`` header that comes from our proxy, and any time its value is ``'https'``, then the request is guaranteed to be secure (i.e., it originally came in via HTTPS). You should *only* set this setting if you control your proxy or have some other guarantee that it sets/strips this header appropriately. Note that the header needs to be in the format as used by ``request.META`` -- all caps and likely starting with ``HTTP_``. (Remember, Django automatically adds ``'HTTP_'`` to the start of x-header names before making the header available in ``request.META``.) .. warning:: **Modifying this setting can compromise your site's security. Ensure you fully understand your setup before changing it.** Make sure ALL of the following are true before setting this (assuming the values from the example above): * Your Django app is behind a proxy. * Your proxy strips the ``X-Forwarded-Proto`` header from all incoming requests. In other words, if end users include that header in their requests, the proxy will discard it. * Your proxy sets the ``X-Forwarded-Proto`` header and sends it to Django, but only for requests that originally come in via HTTPS. If any of those are not true, you should keep this setting set to ``None`` and find another way of determining HTTPS, perhaps via custom middleware. .. setting:: SECURE_REDIRECT_EXEMPT ``SECURE_REDIRECT_EXEMPT`` -------------------------- Default: ``[]`` (Empty list) If a URL path matches a regular expression in this list, the request will not be redirected to HTTPS. The :class:`~django.middleware.security.SecurityMiddleware` strips leading slashes from URL paths, so patterns shouldn't include them, e.g. ``SECURE_REDIRECT_EXEMPT = [r'^no-ssl/$', …]``. If :setting:`SECURE_SSL_REDIRECT` is ``False``, this setting has no effect. .. setting:: SECURE_REFERRER_POLICY ``SECURE_REFERRER_POLICY`` -------------------------- Default: ``'same-origin'`` If configured, the :class:`~django.middleware.security.SecurityMiddleware` sets the :ref:`referrer-policy` header on all responses that do not already have it to the value provided. .. setting:: SECURE_SSL_HOST ``SECURE_SSL_HOST`` ------------------- Default: ``None`` If a string (e.g. ``secure.example.com``), all SSL redirects will be directed to this host rather than the originally-requested host (e.g. ``www.example.com``). If :setting:`SECURE_SSL_REDIRECT` is ``False``, this setting has no effect. .. setting:: SECURE_SSL_REDIRECT ``SECURE_SSL_REDIRECT`` ----------------------- Default: ``False`` If ``True``, the :class:`~django.middleware.security.SecurityMiddleware` :ref:`redirects ` all non-HTTPS requests to HTTPS (except for those URLs matching a regular expression listed in :setting:`SECURE_REDIRECT_EXEMPT`). .. note:: If turning this to ``True`` causes infinite redirects, it probably means your site is running behind a proxy and can't tell which requests are secure and which are not. Your proxy likely sets a header to indicate secure requests; you can correct the problem by finding out what that header is and configuring the :setting:`SECURE_PROXY_SSL_HEADER` setting accordingly. .. setting:: SERIALIZATION_MODULES ``SERIALIZATION_MODULES`` ------------------------- Default: Not defined A dictionary of modules containing serializer definitions (provided as strings), keyed by a string identifier for that serialization type. For example, to define a YAML serializer, use:: SERIALIZATION_MODULES = {'yaml': 'path.to.yaml_serializer'} .. setting:: SERVER_EMAIL ``SERVER_EMAIL`` ---------------- Default: ``'root@localhost'`` The email address that error messages come from, such as those sent to :setting:`ADMINS` and :setting:`MANAGERS`. .. admonition:: Why are my emails sent from a different address? This address is used only for error messages. It is *not* the address that regular email messages sent with :meth:`~django.core.mail.send_mail()` come from; for that, see :setting:`DEFAULT_FROM_EMAIL`. .. setting:: SHORT_DATE_FORMAT ``SHORT_DATE_FORMAT`` --------------------- Default: ``'m/d/Y'`` (e.g. ``12/31/2003``) An available formatting that can be used for displaying date fields on templates. Note that if :setting:`USE_L10N` is set to ``True``, then the corresponding locale-dictated format has higher precedence and will be applied. See :tfilter:`allowed date format strings `. See also :setting:`DATE_FORMAT` and :setting:`SHORT_DATETIME_FORMAT`. .. setting:: SHORT_DATETIME_FORMAT ``SHORT_DATETIME_FORMAT`` ------------------------- Default: ``'m/d/Y P'`` (e.g. ``12/31/2003 4 p.m.``) An available formatting that can be used for displaying datetime fields on templates. Note that if :setting:`USE_L10N` is set to ``True``, then the corresponding locale-dictated format has higher precedence and will be applied. See :tfilter:`allowed date format strings `. See also :setting:`DATE_FORMAT` and :setting:`SHORT_DATE_FORMAT`. .. setting:: SIGNING_BACKEND ``SIGNING_BACKEND`` ------------------- Default: ``'django.core.signing.TimestampSigner'`` The backend used for signing cookies and other data. See also the :doc:`/topics/signing` documentation. .. setting:: SILENCED_SYSTEM_CHECKS ``SILENCED_SYSTEM_CHECKS`` -------------------------- Default: ``[]`` (Empty list) A list of identifiers of messages generated by the system check framework (i.e. ``["models.W001"]``) that you wish to permanently acknowledge and ignore. Silenced checks will not be output to the console. See also the :doc:`/ref/checks` documentation. .. setting:: TEMPLATES ``TEMPLATES`` ------------- Default: ``[]`` (Empty list) A list containing the settings for all template engines to be used with Django. Each item of the list is a dictionary containing the options for an individual engine. Here's a setup that tells the Django template engine to load templates from the ``templates`` subdirectory inside each installed application:: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'APP_DIRS': True, }, ] The following options are available for all backends. .. setting:: TEMPLATES-BACKEND ``BACKEND`` ~~~~~~~~~~~ Default: Not defined The template backend to use. The built-in template backends are: * ``'django.template.backends.django.DjangoTemplates'`` * ``'django.template.backends.jinja2.Jinja2'`` You can use a template backend that doesn't ship with Django by setting ``BACKEND`` to a fully-qualified path (i.e. ``'mypackage.whatever.Backend'``). .. setting:: TEMPLATES-NAME ``NAME`` ~~~~~~~~ Default: see below The alias for this particular template engine. It's an identifier that allows selecting an engine for rendering. Aliases must be unique across all configured template engines. It defaults to the name of the module defining the engine class, i.e. the next to last piece of :setting:`BACKEND `, when it isn't provided. For example if the backend is ``'mypackage.whatever.Backend'`` then its default name is ``'whatever'``. .. setting:: TEMPLATES-DIRS ``DIRS`` ~~~~~~~~ Default: ``[]`` (Empty list) Directories where the engine should look for template source files, in search order. .. setting:: TEMPLATES-APP_DIRS ``APP_DIRS`` ~~~~~~~~~~~~ Default: ``False`` Whether the engine should look for template source files inside installed applications. .. note:: The default :file:`settings.py` file created by :djadmin:`django-admin startproject ` sets ``'APP_DIRS': True``. .. setting:: TEMPLATES-OPTIONS ``OPTIONS`` ~~~~~~~~~~~ Default: ``{}`` (Empty dict) Extra parameters to pass to the template backend. Available parameters vary depending on the template backend. See :class:`~django.template.backends.django.DjangoTemplates` and :class:`~django.template.backends.jinja2.Jinja2` for the options of the built-in backends. .. setting:: TEST_RUNNER ``TEST_RUNNER`` --------------- Default: ``'django.test.runner.DiscoverRunner'`` The name of the class to use for starting the test suite. See :ref:`other-testing-frameworks`. .. setting:: TEST_NON_SERIALIZED_APPS ``TEST_NON_SERIALIZED_APPS`` ---------------------------- Default: ``[]`` (Empty list) In order to restore the database state between tests for ``TransactionTestCase``\s and database backends without transactions, Django will :ref:`serialize the contents of all apps ` when it starts the test run so it can then reload from that copy before running tests that need it. This slows down the startup time of the test runner; if you have apps that you know don't need this feature, you can add their full names in here (e.g. ``'django.contrib.contenttypes'``) to exclude them from this serialization process. .. setting:: THOUSAND_SEPARATOR ``THOUSAND_SEPARATOR`` ---------------------- Default: ``','`` (Comma) Default thousand separator used when formatting numbers. This setting is used only when :setting:`USE_THOUSAND_SEPARATOR` is ``True`` and :setting:`NUMBER_GROUPING` is greater than ``0``. Note that if :setting:`USE_L10N` is set to ``True``, then the locale-dictated format has higher precedence and will be applied instead. See also :setting:`NUMBER_GROUPING`, :setting:`DECIMAL_SEPARATOR` and :setting:`USE_THOUSAND_SEPARATOR`. .. setting:: TIME_FORMAT ``TIME_FORMAT`` --------------- Default: ``'P'`` (e.g. ``4 p.m.``) The default formatting to use for displaying time fields in any part of the system. Note that if :setting:`USE_L10N` is set to ``True``, then the locale-dictated format has higher precedence and will be applied instead. See :tfilter:`allowed date format strings `. See also :setting:`DATE_FORMAT` and :setting:`DATETIME_FORMAT`. .. setting:: TIME_INPUT_FORMATS ``TIME_INPUT_FORMATS`` ---------------------- Default:: [ '%H:%M:%S', # '14:30:59' '%H:%M:%S.%f', # '14:30:59.000200' '%H:%M', # '14:30' ] A list of formats that will be accepted when inputting data on a time field. Formats will be tried in order, using the first valid one. Note that these format strings use Python's :ref:`datetime module syntax `, not the format strings from the :tfilter:`date` template filter. When :setting:`USE_L10N` is ``True``, the locale-dictated format has higher precedence and will be applied instead. See also :setting:`DATE_INPUT_FORMATS` and :setting:`DATETIME_INPUT_FORMATS`. .. setting:: TIME_ZONE ``TIME_ZONE`` ------------- Default: ``'America/Chicago'`` A string representing the time zone for this installation. See the `list of time zones`_. .. note:: Since Django was first released with the :setting:`TIME_ZONE` set to ``'America/Chicago'``, the global setting (used if nothing is defined in your project's ``settings.py``) remains ``'America/Chicago'`` for backwards compatibility. New project templates default to ``'UTC'``. Note that this isn't necessarily the time zone of the server. For example, one server may serve multiple Django-powered sites, each with a separate time zone setting. When :setting:`USE_TZ` is ``False``, this is the time zone in which Django will store all datetimes. When :setting:`USE_TZ` is ``True``, this is the default time zone that Django will use to display datetimes in templates and to interpret datetimes entered in forms. On Unix environments (where :func:`time.tzset` is implemented), Django sets the ``os.environ['TZ']`` variable to the time zone you specify in the :setting:`TIME_ZONE` setting. Thus, all your views and models will automatically operate in this time zone. However, Django won't set the ``TZ`` environment variable if you're using the manual configuration option as described in :ref:`manually configuring settings `. If Django doesn't set the ``TZ`` environment variable, it's up to you to ensure your processes are running in the correct environment. .. note:: Django cannot reliably use alternate time zones in a Windows environment. If you're running Django on Windows, :setting:`TIME_ZONE` must be set to match the system time zone. .. _list of time zones: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones .. setting:: USE_I18N ``USE_I18N`` ------------ Default: ``True`` A boolean that specifies whether Django's translation system should be enabled. This provides a way to turn it off, for performance. If this is set to ``False``, Django will make some optimizations so as not to load the translation machinery. See also :setting:`LANGUAGE_CODE`, :setting:`USE_L10N` and :setting:`USE_TZ`. .. note:: The default :file:`settings.py` file created by :djadmin:`django-admin startproject ` includes ``USE_I18N = True`` for convenience. .. setting:: USE_L10N ``USE_L10N`` ------------ Default: ``False`` A boolean that specifies if localized formatting of data will be enabled by default or not. If this is set to ``True``, e.g. Django will display numbers and dates using the format of the current locale. See also :setting:`LANGUAGE_CODE`, :setting:`USE_I18N` and :setting:`USE_TZ`. .. note:: The default :file:`settings.py` file created by :djadmin:`django-admin startproject ` includes ``USE_L10N = True`` for convenience. .. setting:: USE_THOUSAND_SEPARATOR ``USE_THOUSAND_SEPARATOR`` -------------------------- Default: ``False`` A boolean that specifies whether to display numbers using a thousand separator. When set to ``True`` and :setting:`USE_L10N` is also ``True``, Django will format numbers using the :setting:`NUMBER_GROUPING` and :setting:`THOUSAND_SEPARATOR` settings. These settings may also be dictated by the locale, which takes precedence. See also :setting:`DECIMAL_SEPARATOR`, :setting:`NUMBER_GROUPING` and :setting:`THOUSAND_SEPARATOR`. .. setting:: USE_TZ ``USE_TZ`` ---------- Default: ``False`` A boolean that specifies if datetimes will be timezone-aware by default or not. If this is set to ``True``, Django will use timezone-aware datetimes internally. When ``USE_TZ`` is False, Django will use naive datetimes in local time, except when parsing ISO 8601 formatted strings, where timezone information will always be retained if present. See also :setting:`TIME_ZONE`, :setting:`USE_I18N` and :setting:`USE_L10N`. .. note:: The default :file:`settings.py` file created by :djadmin:`django-admin startproject ` includes ``USE_TZ = True`` for convenience. .. setting:: USE_X_FORWARDED_HOST ``USE_X_FORWARDED_HOST`` ------------------------ Default: ``False`` A boolean that specifies whether to use the ``X-Forwarded-Host`` header in preference to the ``Host`` header. This should only be enabled if a proxy which sets this header is in use. This setting takes priority over :setting:`USE_X_FORWARDED_PORT`. Per :rfc:`7239#section-5.3`, the ``X-Forwarded-Host`` header can include the port number, in which case you shouldn't use :setting:`USE_X_FORWARDED_PORT`. .. setting:: USE_X_FORWARDED_PORT ``USE_X_FORWARDED_PORT`` ------------------------ Default: ``False`` A boolean that specifies whether to use the ``X-Forwarded-Port`` header in preference to the ``SERVER_PORT`` ``META`` variable. This should only be enabled if a proxy which sets this header is in use. :setting:`USE_X_FORWARDED_HOST` takes priority over this setting. .. setting:: WSGI_APPLICATION ``WSGI_APPLICATION`` -------------------- Default: ``None`` The full Python path of the WSGI application object that Django's built-in servers (e.g. :djadmin:`runserver`) will use. The :djadmin:`django-admin startproject ` management command will create a standard ``wsgi.py`` file with an ``application`` callable in it, and point this setting to that ``application``. If not set, the return value of ``django.core.wsgi.get_wsgi_application()`` will be used. In this case, the behavior of :djadmin:`runserver` will be identical to previous Django versions. .. setting:: YEAR_MONTH_FORMAT ``YEAR_MONTH_FORMAT`` --------------------- Default: ``'F Y'`` The default formatting to use for date fields on Django admin change-list pages -- and, possibly, by other parts of the system -- in cases when only the year and month are displayed. For example, when a Django admin change-list page is being filtered by a date drilldown, the header for a given month displays the month and the year. Different locales have different formats. For example, U.S. English would say "January 2006," whereas another locale might say "2006/January." Note that if :setting:`USE_L10N` is set to ``True``, then the corresponding locale-dictated format has higher precedence and will be applied. See :tfilter:`allowed date format strings `. See also :setting:`DATE_FORMAT`, :setting:`DATETIME_FORMAT`, :setting:`TIME_FORMAT` and :setting:`MONTH_DAY_FORMAT`. .. setting:: X_FRAME_OPTIONS ``X_FRAME_OPTIONS`` ------------------- Default: ``'DENY'`` The default value for the X-Frame-Options header used by :class:`~django.middleware.clickjacking.XFrameOptionsMiddleware`. See the :doc:`clickjacking protection ` documentation. Auth ==== Settings for :mod:`django.contrib.auth`. .. setting:: AUTHENTICATION_BACKENDS ``AUTHENTICATION_BACKENDS`` --------------------------- Default: ``['django.contrib.auth.backends.ModelBackend']`` A list of authentication backend classes (as strings) to use when attempting to authenticate a user. See the :ref:`authentication backends documentation ` for details. .. setting:: AUTH_USER_MODEL ``AUTH_USER_MODEL`` ------------------- Default: ``'auth.User'`` The model to use to represent a User. See :ref:`auth-custom-user`. .. warning:: You cannot change the AUTH_USER_MODEL setting during the lifetime of a project (i.e. once you have made and migrated models that depend on it) without serious effort. It is intended to be set at the project start, and the model it refers to must be available in the first migration of the app that it lives in. See :ref:`auth-custom-user` for more details. .. setting:: LOGIN_REDIRECT_URL ``LOGIN_REDIRECT_URL`` ---------------------- Default: ``'/accounts/profile/'`` The URL or :ref:`named URL pattern ` where requests are redirected after login when the :class:`~django.contrib.auth.views.LoginView` doesn't get a ``next`` GET parameter. .. setting:: LOGIN_URL ``LOGIN_URL`` ------------- Default: ``'/accounts/login/'`` The URL or :ref:`named URL pattern ` where requests are redirected for login when using the :func:`~django.contrib.auth.decorators.login_required` decorator, :class:`~django.contrib.auth.mixins.LoginRequiredMixin`, or :class:`~django.contrib.auth.mixins.AccessMixin`. .. setting:: LOGOUT_REDIRECT_URL ``LOGOUT_REDIRECT_URL`` ----------------------- Default: ``None`` The URL or :ref:`named URL pattern ` where requests are redirected after logout if :class:`~django.contrib.auth.views.LogoutView` doesn't have a ``next_page`` attribute. If ``None``, no redirect will be performed and the logout view will be rendered. .. setting:: PASSWORD_RESET_TIMEOUT ``PASSWORD_RESET_TIMEOUT`` -------------------------- Default: ``259200`` (3 days, in seconds) The number of seconds a password reset link is valid for. Used by the :class:`~django.contrib.auth.views.PasswordResetConfirmView`. .. note:: Reducing the value of this timeout doesn't make any difference to the ability of an attacker to brute-force a password reset token. Tokens are designed to be safe from brute-forcing without any timeout. This timeout exists to protect against some unlikely attack scenarios, such as someone gaining access to email archives that may contain old, unused password reset tokens. .. setting:: PASSWORD_HASHERS ``PASSWORD_HASHERS`` -------------------- See :ref:`auth_password_storage`. Default:: [ 'django.contrib.auth.hashers.PBKDF2PasswordHasher', 'django.contrib.auth.hashers.PBKDF2SHA1PasswordHasher', 'django.contrib.auth.hashers.Argon2PasswordHasher', 'django.contrib.auth.hashers.BCryptSHA256PasswordHasher', ] .. setting:: AUTH_PASSWORD_VALIDATORS ``AUTH_PASSWORD_VALIDATORS`` ---------------------------- Default: ``[]`` (Empty list) The list of validators that are used to check the strength of user's passwords. See :ref:`password-validation` for more details. By default, no validation is performed and all passwords are accepted. .. _settings-messages: Messages ======== Settings for :mod:`django.contrib.messages`. .. setting:: MESSAGE_LEVEL ``MESSAGE_LEVEL`` ----------------- Default: ``messages.INFO`` Sets the minimum message level that will be recorded by the messages framework. See :ref:`message levels ` for more details. .. admonition:: Important If you override ``MESSAGE_LEVEL`` in your settings file and rely on any of the built-in constants, you must import the constants module directly to avoid the potential for circular imports, e.g.:: from django.contrib.messages import constants as message_constants MESSAGE_LEVEL = message_constants.DEBUG If desired, you may specify the numeric values for the constants directly according to the values in the above :ref:`constants table `. .. setting:: MESSAGE_STORAGE ``MESSAGE_STORAGE`` ------------------- Default: ``'django.contrib.messages.storage.fallback.FallbackStorage'`` Controls where Django stores message data. Valid values are: * ``'django.contrib.messages.storage.fallback.FallbackStorage'`` * ``'django.contrib.messages.storage.session.SessionStorage'`` * ``'django.contrib.messages.storage.cookie.CookieStorage'`` See :ref:`message storage backends ` for more details. The backends that use cookies -- :class:`~django.contrib.messages.storage.cookie.CookieStorage` and :class:`~django.contrib.messages.storage.fallback.FallbackStorage` -- use the value of :setting:`SESSION_COOKIE_DOMAIN`, :setting:`SESSION_COOKIE_SECURE` and :setting:`SESSION_COOKIE_HTTPONLY` when setting their cookies. .. setting:: MESSAGE_TAGS ``MESSAGE_TAGS`` ---------------- Default:: { messages.DEBUG: 'debug', messages.INFO: 'info', messages.SUCCESS: 'success', messages.WARNING: 'warning', messages.ERROR: 'error', } This sets the mapping of message level to message tag, which is typically rendered as a CSS class in HTML. If you specify a value, it will extend the default. This means you only have to specify those values which you need to override. See :ref:`message-displaying` above for more details. .. admonition:: Important If you override ``MESSAGE_TAGS`` in your settings file and rely on any of the built-in constants, you must import the ``constants`` module directly to avoid the potential for circular imports, e.g.:: from django.contrib.messages import constants as message_constants MESSAGE_TAGS = {message_constants.INFO: ''} If desired, you may specify the numeric values for the constants directly according to the values in the above :ref:`constants table `. .. _settings-sessions: Sessions ======== Settings for :mod:`django.contrib.sessions`. .. setting:: SESSION_CACHE_ALIAS ``SESSION_CACHE_ALIAS`` ----------------------- Default: ``'default'`` If you're using :ref:`cache-based session storage `, this selects the cache to use. .. setting:: SESSION_COOKIE_AGE ``SESSION_COOKIE_AGE`` ---------------------- Default: ``1209600`` (2 weeks, in seconds) The age of session cookies, in seconds. .. setting:: SESSION_COOKIE_DOMAIN ``SESSION_COOKIE_DOMAIN`` ------------------------- Default: ``None`` The domain to use for session cookies. Set this to a string such as ``"example.com"`` for cross-domain cookies, or use ``None`` for a standard domain cookie. To use cross-domain cookies with :setting:`CSRF_USE_SESSIONS`, you must include a leading dot (e.g. ``".example.com"``) to accommodate the CSRF middleware's referer checking. Be cautious when updating this setting on a production site. If you update this setting to enable cross-domain cookies on a site that previously used standard domain cookies, existing user cookies will be set to the old domain. This may result in them being unable to log in as long as these cookies persist. This setting also affects cookies set by :mod:`django.contrib.messages`. .. setting:: SESSION_COOKIE_HTTPONLY ``SESSION_COOKIE_HTTPONLY`` --------------------------- Default: ``True`` Whether to use ``HttpOnly`` flag on the session cookie. If this is set to ``True``, client-side JavaScript will not be able to access the session cookie. HttpOnly_ is a flag included in a Set-Cookie HTTP response header. It's part of the :rfc:`6265#section-4.1.2.6` standard for cookies and can be a useful way to mitigate the risk of a client-side script accessing the protected cookie data. This makes it less trivial for an attacker to escalate a cross-site scripting vulnerability into full hijacking of a user's session. There aren't many good reasons for turning this off. Your code shouldn't read session cookies from JavaScript. .. _HttpOnly: https://owasp.org/www-community/HttpOnly .. setting:: SESSION_COOKIE_NAME ``SESSION_COOKIE_NAME`` ----------------------- Default: ``'sessionid'`` The name of the cookie to use for sessions. This can be whatever you want (as long as it's different from the other cookie names in your application). .. setting:: SESSION_COOKIE_PATH ``SESSION_COOKIE_PATH`` ----------------------- Default: ``'/'`` The path set on the session cookie. This should either match the URL path of your Django installation or be parent of that path. This is useful if you have multiple Django instances running under the same hostname. They can use different cookie paths, and each instance will only see its own session cookie. .. setting:: SESSION_COOKIE_SAMESITE ``SESSION_COOKIE_SAMESITE`` --------------------------- Default: ``'Lax'`` The value of the `SameSite`_ flag on the session cookie. This flag prevents the cookie from being sent in cross-site requests thus preventing CSRF attacks and making some methods of stealing session cookie impossible. Possible values for the setting are: * ``'Strict'``: prevents the cookie from being sent by the browser to the target site in all cross-site browsing context, even when following a regular link. For example, for a GitHub-like website this would mean that if a logged-in user follows a link to a private GitHub project posted on a corporate discussion forum or email, GitHub will not receive the session cookie and the user won't be able to access the project. A bank website, however, most likely doesn't want to allow any transactional pages to be linked from external sites so the ``'Strict'`` flag would be appropriate. * ``'Lax'`` (default): provides a balance between security and usability for websites that want to maintain user's logged-in session after the user arrives from an external link. In the GitHub scenario, the session cookie would be allowed when following a regular link from an external website and be blocked in CSRF-prone request methods (e.g. ``POST``). * ``'None'`` (string): the session cookie will be sent with all same-site and cross-site requests. * ``False``: disables the flag. .. note:: Modern browsers provide a more secure default policy for the ``SameSite`` flag and will assume ``Lax`` for cookies without an explicit value set. .. _SameSite: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite .. setting:: SESSION_COOKIE_SECURE ``SESSION_COOKIE_SECURE`` ------------------------- Default: ``False`` Whether to use a secure cookie for the session cookie. If this is set to ``True``, the cookie will be marked as "secure", which means browsers may ensure that the cookie is only sent under an HTTPS connection. Leaving this setting off isn't a good idea because an attacker could capture an unencrypted session cookie with a packet sniffer and use the cookie to hijack the user's session. .. setting:: SESSION_ENGINE ``SESSION_ENGINE`` ------------------ Default: ``'django.contrib.sessions.backends.db'`` Controls where Django stores session data. Included engines are: * ``'django.contrib.sessions.backends.db'`` * ``'django.contrib.sessions.backends.file'`` * ``'django.contrib.sessions.backends.cache'`` * ``'django.contrib.sessions.backends.cached_db'`` * ``'django.contrib.sessions.backends.signed_cookies'`` See :ref:`configuring-sessions` for more details. .. setting:: SESSION_EXPIRE_AT_BROWSER_CLOSE ``SESSION_EXPIRE_AT_BROWSER_CLOSE`` ----------------------------------- Default: ``False`` Whether to expire the session when the user closes their browser. See :ref:`browser-length-vs-persistent-sessions`. .. setting:: SESSION_FILE_PATH ``SESSION_FILE_PATH`` --------------------- Default: ``None`` If you're using file-based session storage, this sets the directory in which Django will store session data. When the default value (``None``) is used, Django will use the standard temporary directory for the system. .. setting:: SESSION_SAVE_EVERY_REQUEST ``SESSION_SAVE_EVERY_REQUEST`` ------------------------------ Default: ``False`` Whether to save the session data on every request. If this is ``False`` (default), then the session data will only be saved if it has been modified -- that is, if any of its dictionary values have been assigned or deleted. Empty sessions won't be created, even if this setting is active. .. setting:: SESSION_SERIALIZER ``SESSION_SERIALIZER`` ---------------------- Default: ``'django.contrib.sessions.serializers.JSONSerializer'`` Full import path of a serializer class to use for serializing session data. Included serializers are: * ``'django.contrib.sessions.serializers.PickleSerializer'`` * ``'django.contrib.sessions.serializers.JSONSerializer'`` See :ref:`session_serialization` for details, including a warning regarding possible remote code execution when using :class:`~django.contrib.sessions.serializers.PickleSerializer`. Sites ===== Settings for :mod:`django.contrib.sites`. .. setting:: SITE_ID ``SITE_ID`` ----------- Default: Not defined The ID, as an integer, of the current site in the ``django_site`` database table. This is used so that application data can hook into specific sites and a single database can manage content for multiple sites. .. _settings-staticfiles: Static Files ============ Settings for :mod:`django.contrib.staticfiles`. .. setting:: STATIC_ROOT ``STATIC_ROOT`` --------------- Default: ``None`` The absolute path to the directory where :djadmin:`collectstatic` will collect static files for deployment. Example: ``"/var/www/example.com/static/"`` If the :doc:`staticfiles` contrib app is enabled (as in the default project template), the :djadmin:`collectstatic` management command will collect static files into this directory. See the how-to on :doc:`managing static files` for more details about usage. .. warning:: This should be an initially empty destination directory for collecting your static files from their permanent locations into one directory for ease of deployment; it is **not** a place to store your static files permanently. You should do that in directories that will be found by :doc:`staticfiles`’s :setting:`finders`, which by default, are ``'static/'`` app sub-directories and any directories you include in :setting:`STATICFILES_DIRS`). .. setting:: STATIC_URL ``STATIC_URL`` -------------- Default: ``None`` URL to use when referring to static files located in :setting:`STATIC_ROOT`. Example: ``"static/"`` or ``"http://static.example.com/"`` If not ``None``, this will be used as the base path for :ref:`asset definitions` (the ``Media`` class) and the :doc:`staticfiles app`. It must end in a slash if set to a non-empty value. You may need to :ref:`configure these files to be served in development ` and will definitely need to do so :doc:`in production `. .. note:: If :setting:`STATIC_URL` is a relative path, then it will be prefixed by the server-provided value of ``SCRIPT_NAME`` (or ``/`` if not set). This makes it easier to serve a Django application in a subpath without adding an extra configuration to the settings. .. setting:: STATICFILES_DIRS ``STATICFILES_DIRS`` -------------------- Default: ``[]`` (Empty list) This setting defines the additional locations the staticfiles app will traverse if the ``FileSystemFinder`` finder is enabled, e.g. if you use the :djadmin:`collectstatic` or :djadmin:`findstatic` management command or use the static file serving view. This should be set to a list of strings that contain full paths to your additional files directory(ies) e.g.:: STATICFILES_DIRS = [ "/home/special.polls.com/polls/static", "/home/polls.com/polls/static", "/opt/webfiles/common", ] Note that these paths should use Unix-style forward slashes, even on Windows (e.g. ``"C:/Users/user/mysite/extra_static_content"``). .. _staticfiles-dirs-prefixes: Prefixes (optional) ~~~~~~~~~~~~~~~~~~~ In case you want to refer to files in one of the locations with an additional namespace, you can **optionally** provide a prefix as ``(prefix, path)`` tuples, e.g.:: STATICFILES_DIRS = [ # ... ("downloads", "/opt/webfiles/stats"), ] For example, assuming you have :setting:`STATIC_URL` set to ``'static/'``, the :djadmin:`collectstatic` management command would collect the "stats" files in a ``'downloads'`` subdirectory of :setting:`STATIC_ROOT`. This would allow you to refer to the local file ``'/opt/webfiles/stats/polls_20101022.tar.gz'`` with ``'/static/downloads/polls_20101022.tar.gz'`` in your templates, e.g.: .. code-block:: html+django .. setting:: STATICFILES_STORAGE ``STATICFILES_STORAGE`` ----------------------- Default: ``'django.contrib.staticfiles.storage.StaticFilesStorage'`` The file storage engine to use when collecting static files with the :djadmin:`collectstatic` management command. A ready-to-use instance of the storage backend defined in this setting can be found at ``django.contrib.staticfiles.storage.staticfiles_storage``. For an example, see :ref:`staticfiles-from-cdn`. .. setting:: STATICFILES_FINDERS ``STATICFILES_FINDERS`` ----------------------- Default:: [ 'django.contrib.staticfiles.finders.FileSystemFinder', 'django.contrib.staticfiles.finders.AppDirectoriesFinder', ] The list of finder backends that know how to find static files in various locations. The default will find files stored in the :setting:`STATICFILES_DIRS` setting (using ``django.contrib.staticfiles.finders.FileSystemFinder``) and in a ``static`` subdirectory of each app (using ``django.contrib.staticfiles.finders.AppDirectoriesFinder``). If multiple files with the same name are present, the first file that is found will be used. One finder is disabled by default: ``django.contrib.staticfiles.finders.DefaultStorageFinder``. If added to your :setting:`STATICFILES_FINDERS` setting, it will look for static files in the default file storage as defined by the :setting:`DEFAULT_FILE_STORAGE` setting. .. note:: When using the ``AppDirectoriesFinder`` finder, make sure your apps can be found by staticfiles by adding the app to the :setting:`INSTALLED_APPS` setting of your site. Static file finders are currently considered a private interface, and this interface is thus undocumented.
