.. _ref-settings: Available settings ================== Here's a full list of all available settings, in alphabetical order, and their default values. .. 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 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), } Note that the model name used in this setting should be all lower-case, regardless of the case of the actual model class name. .. setting:: ADMIN_FOR ADMIN_FOR --------- Default: ``()`` (Empty tuple) Used for admin-site settings modules, this should be a tuple of settings modules (in the format ``'foo.bar.baz'``) for which this site is an admin. The admin site uses this in its automatically-introspected documentation of models, views and template tags. .. setting:: ADMIN_MEDIA_PREFIX ADMIN_MEDIA_PREFIX ------------------ Default: ``'/media/'`` The URL prefix for admin media -- CSS, JavaScript and images used by the Django administrative interface. Make sure to use a trailing slash, and to have this be different from the ``MEDIA_URL`` setting (since the same URL cannot be mapped onto two different sets of files). .. setting:: ADMINS ADMINS ------ Default: ``()`` (Empty tuple) A tuple that lists people who get code error notifications. When ``DEBUG=False`` and a view raises an exception, Django will e-mail these people with the full exception information. Each member of the tuple should be a tuple of (Full name, e-mail address). Example:: (('John', 'john@example.com'), ('Mary', 'mary@example.com')) Note that Django will e-mail *all* of these people whenever an error happens. See :ref:`howto-error-reporting` for more information. .. setting:: ALLOWED_INCLUDE_ROOTS ALLOWED_INCLUDE_ROOTS --------------------- Default: ``()`` (Empty tuple) A tuple of strings representing allowed prefixes for the ``{% ssi %}`` template tag. This is a security measure, so that template authors can't access files that they shouldn't be accessing. For example, if ``ALLOWED_INCLUDE_ROOTS`` is ``('/home/html', '/var/www')``, then ``{% ssi /home/html/foo.txt %}`` would work, but ``{% ssi /etc/passwd %}`` wouldn't. .. setting:: APPEND_SLASH APPEND_SLASH ------------ Default: ``True`` Whether to append trailing slashes to URLs. This is only used if ``CommonMiddleware`` is installed (see :ref:`topics-http-middleware`). See also ``PREPEND_WWW``. .. setting:: AUTHENTICATION_BACKENDS AUTHENTICATION_BACKENDS ----------------------- Default: ``('django.contrib.auth.backends.ModelBackend',)`` A tuple of authentication backend classes (as strings) to use when attempting to authenticate a user. See the :ref:`authentication backends documentation ` for details. .. setting:: AUTH_PROFILE_MODULE AUTH_PROFILE_MODULE ------------------- Default: Not defined The site-specific user profile model used by this site. See :ref:`auth-profiles`. .. setting:: CACHE_BACKEND CACHE_BACKEND ------------- Default: ``'locmem://'`` The cache backend to use. See :ref:`topics-cache`. .. setting:: CACHE_MIDDLEWARE_KEY_PREFIX CACHE_MIDDLEWARE_KEY_PREFIX --------------------------- Default: ``''`` (Empty string) The cache key prefix that the cache middleware should use. See :ref:`topics-cache`. .. setting:: CACHE_MIDDLEWARE_SECONDS CACHE_MIDDLEWARE_SECONDS ------------------------ Default: ``600`` The default number of seconds to cache a page when the caching middleware or ``cache_page()`` decorator is used. .. setting:: DATABASE_ENGINE DATABASE_ENGINE --------------- Default: ``''`` (Empty string) The database backend to use. The built-in database backends are ``'postgresql_psycopg2'``, ``'postgresql'``, ``'mysql'``, ``'sqlite3'``, and ``'oracle'``. You can use a database backend that doesn't ship with Django by setting ``DATABASE_ENGINE`` to a fully-qualified path (i.e. ``mypackage.backends.whatever``). Writing a whole new database backend from scratch is left as an exercise to the reader; see the other backends for examples. .. versionadded:: 1.0 Support for external database backends is new in 1.0. .. setting:: DATABASE_HOST DATABASE_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:: DATABASE_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, an empty string means to use a Unix domain socket for the connection, rather than a network connection to localhost. If you explicitly need to use a TCP/IP connection on the local machine with PostgreSQL, specify ``localhost`` here. .. setting:: DATABASE_NAME DATABASE_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:: DATABASE_OPTIONS DATABASE_OPTIONS ---------------- Default: ``{}`` (Empty dictionary) Extra parameters to use when connecting to the database. Consult backend module's document for available keywords. .. setting:: DATABASE_PASSWORD DATABASE_PASSWORD ----------------- Default: ``''`` (Empty string) The password to use when connecting to the database. Not used with SQLite. .. setting:: DATABASE_PORT DATABASE_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_USER DATABASE_USER ------------- Default: ``''`` (Empty string) The username to use when connecting to the database. Not used with SQLite. .. setting:: DATE_FORMAT DATE_FORMAT ----------- Default: ``'N j, Y'`` (e.g. ``Feb. 4, 2003``) The default formatting to use for date fields on Django admin change-list pages -- and, possibly, by other parts of the system. See :ttag:`allowed date format strings `. See also ``DATETIME_FORMAT``, ``TIME_FORMAT``, ``YEAR_MONTH_FORMAT`` and ``MONTH_DAY_FORMAT``. .. setting:: DATETIME_FORMAT DATETIME_FORMAT --------------- Default: ``'N j, Y, P'`` (e.g. ``Feb. 4, 2003, 4 p.m.``) The default formatting to use for datetime fields on Django admin change-list pages -- and, possibly, by other parts of the system. See :ttag:`allowed date format strings `. See also ``DATE_FORMAT``, ``DATETIME_FORMAT``, ``TIME_FORMAT``, ``YEAR_MONTH_FORMAT`` and ``MONTH_DAY_FORMAT``. .. setting:: DEBUG DEBUG ----- Default: ``False`` A boolean that turns on/off debug mode. If you define custom settings, `django/views/debug.py`_ has a ``HIDDEN_SETTINGS`` regular expression which will hide from the DEBUG view anything that contains ``'SECRET'``, ``'PASSWORD'``, or ``'PROFANITIES'``. This allows untrusted users to be able to give backtraces without seeing sensitive (or offensive) settings. 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 ``DEBUG`` turned on, Django will remember every SQL query it executes. This is useful when you are debugging, but on a production server, it will rapidly consume memory. Never deploy a site into production with ``DEBUG`` turned on. .. _django/views/debug.py: http://code.djangoproject.com/browser/django/trunk/django/views/debug.py DEBUG_PROPAGATE_EXCEPTIONS -------------------------- .. versionadded:: 1.0 Default: ``False`` If set to True, Django's normal exception handling of view functions will be suppressed, and exceptions will propagate upwards. This can be useful for some test setups, and should never be used on a live site. .. 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 with ``DEFAULT_CONTENT_TYPE`` to construct the ``Content-Type`` header. .. setting:: DEFAULT_CONTENT_TYPE DEFAULT_CONTENT_TYPE -------------------- Default: ``'text/html'`` Default content type to use for all ``HttpResponse`` objects, if a MIME type isn't manually specified. Used with ``DEFAULT_CHARSET`` to construct the ``Content-Type`` header. .. setting:: DEFAULT_FROM_EMAIL DEFAULT_FILE_STORAGE -------------------- Default: ``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 :ref:`topics-files`. DEFAULT_FROM_EMAIL ------------------ Default: ``'webmaster@localhost'`` Default e-mail address to use for various automated correspondence from the site manager(s). .. setting:: DEFAULT_TABLESPACE DEFAULT_TABLESPACE ------------------ .. versionadded:: 1.0 Default: ``''`` (Empty string) Default tablespace to use for models that don't specify one, if the backend supports it. .. setting:: DEFAULT_INDEX_TABLESPACE DEFAULT_INDEX_TABLESPACE ------------------------ .. versionadded:: 1.0 Default: ``''`` (Empty string) Default tablespace to use for indexes on fields that don't specify one, if the backend supports it. .. setting:: DISALLOWED_USER_AGENTS DISALLOWED_USER_AGENTS ---------------------- Default: ``()`` (Empty tuple) List of compiled regular expression objects representing User-Agent strings that are not allowed to visit any page, systemwide. Use this for bad robots/crawlers. This is only used if ``CommonMiddleware`` is installed (see :ref:`topics-http-middleware`). .. setting:: EMAIL_HOST EMAIL_HOST ---------- Default: ``'localhost'`` The host to use for sending e-mail. See also ``EMAIL_PORT``. .. setting:: EMAIL_HOST_PASSWORD EMAIL_HOST_PASSWORD ------------------- Default: ``''`` (Empty string) Password to use for the SMTP server defined in ``EMAIL_HOST``. This setting is used in conjunction with ``EMAIL_HOST_USER`` when authenticating to the SMTP server. If either of these settings is empty, Django won't attempt authentication. See also ``EMAIL_HOST_USER``. .. setting:: EMAIL_HOST_USER EMAIL_HOST_USER --------------- Default: ``''`` (Empty string) Username to use for the SMTP server defined in ``EMAIL_HOST``. If empty, Django won't attempt authentication. See also ``EMAIL_HOST_PASSWORD``. .. setting:: EMAIL_PORT EMAIL_PORT ---------- Default: ``25`` Port to use for the SMTP server defined in ``EMAIL_HOST``. .. setting:: EMAIL_SUBJECT_PREFIX EMAIL_SUBJECT_PREFIX -------------------- Default: ``'[Django] '`` Subject-line prefix for e-mail 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_TLS EMAIL_USE_TLS ------------- .. versionadded:: 1.0 Default: ``False`` Whether to use a TLS (secure) connection when talking to the SMTP server. .. setting:: FILE_CHARSET FILE_CHARSET ------------ .. versionadded:: 1.0 Default: ``'utf-8'`` The character encoding used to decode any files read from disk. This includes template files and initial SQL data files. .. setting:: FILE_UPLOAD_HANDLERS FILE_UPLOAD_HANDLERS -------------------- .. versionadded:: 1.0 Default:: ("django.core.files.uploadhandler.MemoryFileUploadHandler", "django.core.files.uploadhandler.TemporaryFileUploadHandler",) A tuple of handlers to use for uploading. See :ref:`topics-files` for details. .. setting:: FILE_UPLOAD_MAX_MEMORY_SIZE FILE_UPLOAD_MAX_MEMORY_SIZE --------------------------- .. versionadded:: 1.0 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 :ref:`topics-files` for details. .. setting:: FILE_UPLOAD_TEMP_DIR FILE_UPLOAD_TEMP_DIR -------------------- .. versionadded:: 1.0 Default: ``None`` The directory to store data 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 :ref:`topics-files` for details. .. setting:: FILE_UPLOAD_PERMISSIONS FILE_UPLOAD_PERMISSIONS ----------------------- Default: ``None`` The numeric mode (i.e. ``0644``) to set newly uploaded files to. For more information about what these modes mean, see the `documentation for os.chmod`_ If this isn't given or is ``None``, you'll get operating-system dependent behavior. On most platforms, temporary files will have a mode of ``0600``, and files saved from memory will be saved using the system's standard umask. .. warning:: **Always prefix the mode with a 0.** If you're not familiar with file modes, please note that the leading ``0`` 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. .. _documentation for os.chmod: http://docs.python.org/lib/os-file-dir.html .. setting:: FIXTURE_DIRS FIXTURE_DIRS ------------- Default: ``()`` (Empty tuple) List of locations of the fixture data files, in search order. Note that these paths should use Unix-style forward slashes, even on Windows. See :ref:`topics-testing`. 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. .. setting:: IGNORABLE_404_ENDS IGNORABLE_404_ENDS ------------------ Default: ``('mail.pl', 'mailform.pl', 'mail.cgi', 'mailform.cgi', 'favicon.ico', '.php')`` See also ``IGNORABLE_404_STARTS`` and ``Error reporting via e-mail``. .. setting:: IGNORABLE_404_STARTS IGNORABLE_404_STARTS -------------------- Default: ``('/cgi-bin/', '/_vti_bin', '/_vti_inf')`` A tuple of strings that specify beginnings of URLs that should be ignored by the 404 e-mailer. See ``SEND_BROKEN_LINK_EMAILS``, ``IGNORABLE_404_ENDS`` and the :ref:`howto-error-reporting`. .. setting:: INSTALLED_APPS INSTALLED_APPS -------------- Default: ``()`` (Empty tuple) A tuple of strings designating all applications that are enabled in this Django installation. Each string should be a full Python path to a Python package that contains a Django application, as created by :djadmin:`django-admin.py startapp `. .. setting:: INTERNAL_IPS INTERNAL_IPS ------------ Default: ``()`` (Empty tuple) A tuple of IP addresses, as strings, that: * See debug comments, when ``DEBUG`` is ``True`` * Receive X headers if the ``XViewMiddleware`` is installed (see :ref:`topics-http-middleware`) .. setting:: JING_PATH JING_PATH --------- Default: ``'/usr/bin/jing'`` Path to the "Jing" executable. Jing is a RELAX NG validator, and Django uses it to validate each ``XMLField`` in your models. See http://www.thaiopensource.com/relaxng/jing.html . .. setting:: LANGUAGE_CODE LANGUAGE_CODE ------------- Default: ``'en-us'`` A string representing the language code for this installation. This should be in standard language format. For example, U.S. English is ``"en-us"``. See :ref:`topics-i18n`. .. setting:: LANGUAGE_COOKIE_NAME LANGUAGE_COOKIE_NAME -------------------- .. versionadded:: 1.0 Default: ``'django_language'`` The name of the cookie to use for the language cookie. This can be whatever you want (but should be different from ``SESSION_COOKIE_NAME``). See :ref:`topics-i18n`. .. setting:: LANGUAGES LANGUAGES --------- Default: A tuple 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 ``django/conf/global_settings.py`` (or view the `online source`_). .. _online source: http://code.djangoproject.com/browser/django/trunk/django/conf/global_settings.py The list is a tuple of two-tuples in the format (language code, language name) -- for example, ``('ja', 'Japanese')``. This specifies which languages are available for language selection. See :ref:`topics-i18n`. 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 ``LANGUAGES`` setting, it's OK to mark the languages as translation strings (as in the default value displayed above) -- but use a "dummy" ``gettext()`` function, not the one in ``django.utils.translation``. You should *never* import ``django.utils.translation`` from within your settings file, because that module in itself depends on the settings, and that would cause a circular import. The solution is to use a "dummy" ``gettext()`` function. Here's a sample settings file:: gettext = lambda s: s LANGUAGES = ( ('de', gettext('German')), ('en', gettext('English')), ) With this arrangement, ``django-admin.py makemessages`` will still find and mark these strings for translation, but the translation won't happen at runtime -- so you'll have to remember to wrap the languages in the *real* ``gettext()`` in any code that uses ``LANGUAGES`` at runtime. .. setting:: LOCALE_PATHS LOCALE_PATHS ------------ Default: ``()`` (Empty tuple) A tuple of directories where Django looks for translation files. See :ref:`translations-in-your-own-projects`. .. setting:: LOGIN_REDIRECT_URL LOGIN_REDIRECT_URL ------------------ .. versionadded:: 1.0 Default: ``'/accounts/profile/'`` The URL where requests are redirected after login when the ``contrib.auth.login`` view gets no ``next`` parameter. This is used by the :func:`~django.contrib.auth.decorators.login_required` decorator, for example. .. setting:: LOGIN_URL LOGIN_URL --------- .. versionadded:: 1.0 Default: ``'/accounts/login/'`` The URL where requests are redirected for login, specially when using the :func:`~django.contrib.auth.decorators.login_required` decorator. .. setting:: LOGOUT_URL LOGOUT_URL ---------- .. versionadded:: 1.0 Default: ``'/accounts/logout/'`` LOGIN_URL counterpart. .. setting:: MANAGERS MANAGERS -------- Default: ``()`` (Empty tuple) A tuple in the same format as ``ADMINS`` that specifies who should get broken-link notifications when ``SEND_BROKEN_LINK_EMAILS=True``. .. setting:: MEDIA_ROOT MEDIA_ROOT ---------- Default: ``''`` (Empty string) Absolute path to the directory that holds media for this installation. Example: ``"/home/media/media.lawrence.com/"`` See also ``MEDIA_URL``. .. setting:: MEDIA_URL MEDIA_URL --------- Default: ``''`` (Empty string) URL that handles the media served from ``MEDIA_ROOT``. Example: ``"http://media.lawrence.com"`` Note that this should have a trailing slash if it has a path component. Good: ``"http://www.example.com/static/"`` Bad: ``"http://www.example.com/static"`` .. setting:: MIDDLEWARE_CLASSES MIDDLEWARE_CLASSES ------------------ Default:: ("django.contrib.csrf.middleware.CsrfViewMiddleware", "django.contrib.csrf.middleware.CsrfResponseMiddleware", "django.contrib.sessions.middleware.SessionMiddleware", "django.contrib.auth.middleware.AuthenticationMiddleware", "django.middleware.common.CommonMiddleware") A tuple of middleware classes to use. See :ref:`topics-http-middleware`. .. 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." See :ttag:`allowed date format strings `. See also ``DATE_FORMAT``, ``DATETIME_FORMAT``, ``TIME_FORMAT`` and ``YEAR_MONTH_FORMAT``. .. 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 ``CommonMiddleware`` is installed (see :ref:`topics-http-middleware`). See also ``APPEND_SLASH``. .. setting:: PROFANITIES_LIST PROFANITIES_LIST ---------------- A tuple of profanities, as strings, that will trigger a validation error when the ``hasNoProfanities`` validator is called. We don't list the default values here, because that would be profane. To see the default values, see the file `django/conf/global_settings.py`_. .. _django/conf/global_settings.py: http://code.djangoproject.com/browser/django/trunk/django/conf/global_settings.py .. 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 this particular Django installation. Used to provide a seed in secret-key hashing algorithms. Set this to a random string -- the longer, the better. ``django-admin.py startproject`` creates one automatically. .. setting:: SEND_BROKEN_LINK_EMAILS SEND_BROKEN_LINK_EMAILS ----------------------- Default: ``False`` Whether to send an e-mail to the ``MANAGERS`` each time somebody visits a Django-powered page that is 404ed with a non-empty referer (i.e., a broken link). This is only used if ``CommonMiddleware`` is installed (see :ref:`topics-http-middleware`. See also ``IGNORABLE_404_STARTS``, ``IGNORABLE_404_ENDS`` and :ref:`howto-error-reporting`. .. 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 e-mail address that error messages come from, such as those sent to ``ADMINS`` and ``MANAGERS``. .. setting:: SESSION_ENGINE SESSION_ENGINE -------------- .. versionadded:: 1.0 Default: ``django.contrib.sessions.backends.db`` Controls where Django stores session data. Valid values are: * ``'django.contrib.sessions.backends.db'`` * ``'django.contrib.sessions.backends.file'`` * ``'django.contrib.sessions.backends.cache'`` See :ref:`topics-http-sessions`. .. setting:: SESSION_COOKIE_AGE SESSION_COOKIE_AGE ------------------ Default: ``1209600`` (2 weeks, in seconds) The age of session cookies, in seconds. See :ref:`topics-http-sessions`. .. setting:: SESSION_COOKIE_DOMAIN SESSION_COOKIE_DOMAIN --------------------- Default: ``None`` The domain to use for session cookies. Set this to a string such as ``".lawrence.com"`` for cross-domain cookies, or use ``None`` for a standard domain cookie. See the :ref:`topics-http-sessions`. .. setting:: SESSION_COOKIE_NAME SESSION_COOKIE_NAME ------------------- Default: ``'sessionid'`` The name of the cookie to use for sessions. This can be whatever you want (but should be different from ``LANGUAGE_COOKIE_NAME``). See the :ref:`topics-http-sessions`. .. setting:: SESSION_COOKIE_PATH SESSION_COOKIE_PATH ------------------- .. versionadded:: 1.0 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_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. See the :ref:`topics-http-sessions`. .. setting:: SESSION_EXPIRE_AT_BROWSER_CLOSE SESSION_EXPIRE_AT_BROWSER_CLOSE ------------------------------- Default: ``False`` Whether to expire the session when the user closes his or her browser. See the :ref:`topics-http-sessions`. .. setting:: SESSION_FILE_PATH SESSION_FILE_PATH ----------------- .. versionadded:: 1.0 Default: ``None`` If you're using file-based session storage, this sets the directory in which Django will store session data. See :ref:`topics-http-sessions`. 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. See :ref:`topics-http-sessions`. .. 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 site(s) and a single database can manage content for multiple sites. See :ref:`ref-contrib-sites`. .. _site framework docs: ../sites/ .. setting:: TEMPLATE_CONTEXT_PROCESSORS TEMPLATE_CONTEXT_PROCESSORS --------------------------- Default:: ("django.core.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "django.core.context_processors.media") A tuple of callables that are used to populate the context in ``RequestContext``. These callables take a request object as their argument and return a dictionary of items to be merged into the context. .. setting:: TEMPLATE_DEBUG TEMPLATE_DEBUG -------------- Default: ``False`` A boolean that turns on/off template debug mode. If this is ``True``, the fancy error page will display a detailed report for any ``TemplateSyntaxError``. This report contains the relevant snippet of the template, with the appropriate line highlighted. Note that Django only displays fancy error pages if ``DEBUG`` is ``True``, so you'll want to set that to take advantage of this setting. See also ``DEBUG``. .. setting:: TEMPLATE_DIRS TEMPLATE_DIRS ------------- Default: ``()`` (Empty tuple) List of locations of the template source files, in search order. Note that these paths should use Unix-style forward slashes, even on Windows. See :ref:`topics-templates`.. .. setting:: TEMPLATE_LOADERS TEMPLATE_LOADERS ---------------- Default:: ('django.template.loaders.filesystem.load_template_source', 'django.template.loaders.app_directories.load_template_source') A tuple of callables (as strings) that know how to import templates from various sources. See :ref:`ref-templates-api`. .. setting:: TEMPLATE_STRING_IF_INVALID TEMPLATE_STRING_IF_INVALID -------------------------- Default: ``''`` (Empty string) Output, as a string, that the template system should use for invalid (e.g. misspelled) variables. See :ref:`invalid-template-variables`.. .. setting:: TEST_DATABASE_CHARSET TEST_DATABASE_CHARSET --------------------- .. versionadded:: 1.0 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 for the PostgreSQL_ (``postgresql``, ``postgresql_psycopg2``) and MySQL_ (``mysql``) backends. .. _PostgreSQL: http://www.postgresql.org/docs/8.2/static/multibyte.html .. _MySQL: http://www.mysql.org/doc/refman/5.0/en/charset-database.html .. setting:: TEST_DATABASE_COLLATION TEST_DATABASE_COLLATION ------------------------ .. versionadded:: 1.0 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 `section 10.3.2`_ of the MySQL manual for details). .. _section 10.3.2: http://www.mysql.org/doc/refman/5.0/en/charset-database.html .. setting:: TEST_DATABASE_NAME TEST_DATABASE_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_' + settings.DATABASE_NAME``. See :ref:`topics-testing`. .. setting:: TEST_RUNNER TEST_RUNNER ----------- Default: ``'django.test.simple.run_tests'`` The name of the method to use for starting the test suite. See :ref:`topics-testing`. .. _Testing Django Applications: ../testing/ .. setting:: TIME_FORMAT TIME_FORMAT ----------- Default: ``'P'`` (e.g. ``4 p.m.``) The default formatting to use for time fields on Django admin change-list pages -- and, possibly, by other parts of the system. See :ttag:`allowed date format strings `. See also ``DATE_FORMAT``, ``DATETIME_FORMAT``, ``TIME_FORMAT``, ``YEAR_MONTH_FORMAT`` and ``MONTH_DAY_FORMAT``. .. setting:: TIME_ZONE TIME_ZONE --------- Default: ``'America/Chicago'`` A string representing the time zone for this installation. `See available choices`_. (Note that list of available choices lists more than one on the same line; you'll want to use just one of the choices for a given time zone. For instance, one line says ``'Europe/London GB GB-Eire'``, but you should use the first bit of that -- ``'Europe/London'`` -- as your ``TIME_ZONE`` setting.) Note that this is the time zone to which Django will convert all dates/times -- not necessarily the timezone of the server. For example, one server may serve multiple Django-powered sites, each with a separate time-zone setting. Normally, Django sets the ``os.environ['TZ']`` variable to the time zone you specify in the ``TIME_ZONE`` setting. Thus, all your views and models will automatically operate in the correct time zone. However, if you're manually :ref:`manually configuring settings `, Django will *not* touch the ``TZ`` environment variable, and it'll be 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, this variable must be set to match the system timezone. .. _See available choices: http://www.postgresql.org/docs/8.1/static/datetime-keywords.html#DATETIME-TIMEZONE-SET-TABLE .. setting:: URL_VALIDATOR_USER_AGENT URL_VALIDATOR_USER_AGENT ------------------------ Default: ``Django/ (http://www.djangoproject.com/)`` The string to use as the ``User-Agent`` header when checking to see if URLs exist (see the ``verify_exists`` option on :class:`~django.db.models.URLField`). .. setting:: USE_ETAGS USE_ETAGS --------- Default: ``False`` A boolean that specifies whether to output the "Etag" header. This saves bandwidth but slows down performance. This is only used if ``CommonMiddleware`` is installed (see :ref:`topics-http-middleware`). .. setting:: USE_I18N USE_I18N -------- Default: ``True`` A boolean that specifies whether Django's internationalization system should be enabled. This provides an easy way to turn it off, for performance. If this is set to ``False``, Django will make some optimizations so as not to load the internationalization machinery. .. 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." See :ttag:`allowed date format strings `. See also ``DATE_FORMAT``, ``DATETIME_FORMAT``, ``TIME_FORMAT`` and ``MONTH_DAY_FORMAT``.
