============================= django-admin.py and manage.py ============================= ``django-admin.py`` is Django's command-line utility for administrative tasks. This document outlines all it can do. In addition, ``manage.py`` is automatically created in each Django project. ``manage.py`` is a thin wrapper around ``django-admin.py`` that takes care of two things for you before delegating to ``django-admin.py``: * It puts your project's package on ``sys.path``. * It sets the ``DJANGO_SETTINGS_MODULE`` environment variable so that it points to your project's ``settings.py`` file. The ``django-admin.py`` script should be on your system path if you installed Django via its ``setup.py`` utility. If it's not on your path, you can find it in ``site-packages/django/bin`` within your Python installation. Consider symlinking it from some place on your path, such as ``/usr/local/bin``. For Windows users, who do not have symlinking functionality available, you can copy ``django-admin.py`` to a location on your existing path or edit the ``PATH`` settings (under ``Settings - Control Panel - System - Advanced - Environment...``) to point to its installed location. Generally, when working on a single Django project, it's easier to use ``manage.py``. Use ``django-admin.py`` with ``DJANGO_SETTINGS_MODULE``, or the ``--settings`` command line option, if you need to switch between multiple Django settings files. The command-line examples throughout this document use ``django-admin.py`` to be consistent, but any example can use ``manage.py`` just as well. Usage ===== ``django-admin.py action [options]`` ``manage.py action [options]`` ``action`` should be one of the actions listed in this document. ``options``, which is optional, should be zero or more of the options listed in this document. Run ``django-admin.py --help`` to display a help message that includes a terse list of all available actions and options. Most actions take a list of ``appname``s. An ``appname`` is the basename of the package containing your models. For example, if your ``INSTALLED_APPS`` contains the string ``'mysite.blog'``, the ``appname`` is ``blog``. Available actions ================= adminindex [appname appname ...] -------------------------------- Prints the admin-index template snippet for the given appnames. Use admin-index template snippets if you want to customize the look and feel of your admin's index page. See `Tutorial 2`_ for more information. .. _Tutorial 2: ../tutorial2/ createcachetable [tablename] ---------------------------- Creates a cache table named ``tablename`` for use with the database cache backend. See the `cache documentation`_ for more information. .. _cache documentation: ../cache/ dbshell ------- Runs the command-line client for the database engine specified in your ``DATABASE_ENGINE`` setting, with the connection parameters specified in your ``DATABASE_USER``, ``DATABASE_PASSWORD``, etc., settings. * For PostgreSQL, this runs the ``psql`` command-line client. * For MySQL, this runs the ``mysql`` command-line client. * For SQLite, this runs the ``sqlite3`` command-line client. This command assumes the programs are on your ``PATH`` so that a simple call to the program name (``psql``, ``mysql``, ``sqlite3``) will find the program in the right place. There's no way to specify the location of the program manually. diffsettings ------------ Displays differences between the current settings file and Django's default settings. Settings that don't appear in the defaults are followed by ``"###"``. For example, the default settings don't define ``ROOT_URLCONF``, so ``ROOT_URLCONF`` is followed by ``"###"`` in the output of ``diffsettings``. Note that Django's default settings live in ``django/conf/global_settings.py``, if you're ever curious to see the full list of defaults. dumpdata [appname appname ...] ------------------------------ Output to standard output all data in the database associated with the named application(s). By default, the database will be dumped in JSON format. If you want the output to be in another format, use the ``--format`` option (e.g., ``format=xml``). You may specify any Django serialization backend (including any user specified serialization backends named in the ``SERIALIZATION_MODULES`` setting). The ``--indent`` option can be used to pretty-print the output. If no application name is provided, all installed applications will be dumped. The output of ``dumpdata`` can be used as input for ``loaddata``. flush ----- Return the database to the state it was in immediately after syncdb was executed. This means that all data will be removed from the database, any post-synchronization handlers will be re-executed, and the ``initial_data`` fixture will be re-installed. inspectdb --------- Introspects the database tables in the database pointed-to by the ``DATABASE_NAME`` setting and outputs a Django model module (a ``models.py`` file) to standard output. Use this if you have a legacy database with which you'd like to use Django. The script will inspect the database and create a model for each table within it. As you might expect, the created models will have an attribute for every field in the table. Note that ``inspectdb`` has a few special cases in its field-name output: * If ``inspectdb`` cannot map a column's type to a model field type, it'll use ``TextField`` and will insert the Python comment ``'This field type is a guess.'`` next to the field in the generated model. * If the database column name is a Python reserved word (such as ``'pass'``, ``'class'`` or ``'for'``), ``inspectdb`` will append ``'_field'`` to the attribute name. For example, if a table has a column ``'for'``, the generated model will have a field ``'for_field'``, with the ``db_column`` attribute set to ``'for'``. ``inspectdb`` will insert the Python comment ``'Field renamed because it was a Python reserved word.'`` next to the field. This feature is meant as a shortcut, not as definitive model generation. After you run it, you'll want to look over the generated models yourself to make customizations. In particular, you'll need to rearrange models' order, so that models that refer to other models are ordered properly. Primary keys are automatically introspected for PostgreSQL, MySQL and SQLite, in which case Django puts in the ``primary_key=True`` where needed. ``inspectdb`` works with PostgreSQL, MySQL and SQLite. Foreign-key detection only works in PostgreSQL and with certain types of MySQL tables. loaddata [fixture fixture ...] ------------------------------ Searches for and loads the contents of the named fixture into the database. A *Fixture* is a collection of files that contain the serialized contents of the database. Each fixture has a unique name; however, the files that comprise the fixture can be distributed over multiple directories, in multiple applications. Django will search in three locations for fixtures: 1. In the ``fixtures`` directory of every installed application 2. In any directory named in the ``FIXTURE_DIRS`` setting 3. In the literal path named by the fixture Django will load any and all fixtures it finds in these locations that match the provided fixture names. If the named fixture has a file extension, only fixtures of that type will be loaded. For example:: django-admin.py loaddata mydata.json would only load JSON fixtures called ``mydata``. The fixture extension must correspond to the registered name of a serializer (e.g., ``json`` or ``xml``). If you omit the extension, Django will search all available fixture types for a matching fixture. For example:: django-admin.py loaddata mydata would look for any fixture of any fixture type called ``mydata``. If a fixture directory contained ``mydata.json``, that fixture would be loaded as a JSON fixture. However, if two fixtures with the same name but different fixture type are discovered (for example, if ``mydata.json`` and ``mydata.xml`` were found in the same fixture directory), fixture installation will be aborted, and any data installed in the call to ``loaddata`` will be removed from the database. The fixtures that are named can include directory components. These directories will be included in the search path. For example:: django-admin.py loaddata foo/bar/mydata.json would search ``/fixtures/foo/bar/mydata.json`` for each installed application, ``/foo/bar/mydata.json`` for each directory in ``FIXTURE_DIRS``, and the literal path ``foo/bar/mydata.json``. Note that the order in which fixture files are processed is undefined. However, all fixture data is installed as a single transaction, so data in one fixture can reference data in another fixture. If the database backend supports row-level constraints, these constraints will be checked at the end of the transaction. The ``dumpdata`` command can be used to generate input for ``loaddata``. .. admonition:: MySQL and Fixtures Unfortunately, MySQL isn't capable of completely supporting all the features of Django fixtures. If you use MyISAM tables, MySQL doesn't support transactions or constraints, so you won't get a rollback if multiple transaction files are found, or validation of fixture data. If you use InnoDB tables, you won't be able to have any forward references in your data files - MySQL doesn't provide a mechanism to defer checking of row constraints until a transaction is committed. reset [appname appname ...] --------------------------- Executes the equivalent of ``sqlreset`` for the given appnames. runfcgi [options] ----------------- Starts a set of FastCGI processes suitable for use with any web server which supports the FastCGI protocol. See the `FastCGI deployment documentation`_ for details. Requires the Python FastCGI module from `flup`_. .. _FastCGI deployment documentation: ../fastcgi/ .. _flup: http://www.saddi.com/software/flup/ runserver [optional port number, or ipaddr:port] ------------------------------------------------ Starts a lightweight development Web server on the local machine. By default, the server runs on port 8000 on the IP address 127.0.0.1. You can pass in an IP address and port number explicitly. If you run this script as a user with normal privileges (recommended), you might not have access to start a port on a low port number. Low port numbers are reserved for the superuser (root). DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. (And that's how it's gonna stay. We're in the business of making Web frameworks, not Web servers, so improving this server to be able to handle a production environment is outside the scope of Django.) The development server automatically reloads Python code for each request, as needed. You don't need to restart the server for code changes to take effect. When you start the server, and each time you change Python code while the server is running, the server will validate all of your installed models. (See the ``validate`` command below.) If the validator finds errors, it will print them to standard output, but it won't stop the server. You can run as many servers as you want, as long as they're on separate ports. Just execute ``django-admin.py runserver`` more than once. Note that the default IP address, 127.0.0.1, is not accessible from other machines on your network. To make your development server viewable to other machines on the network, use its own IP address (e.g. ``192.168.2.1``) or ``0.0.0.0``. Examples: ~~~~~~~~~ Port 7000 on IP address 127.0.0.1:: django-admin.py runserver 7000 Port 7000 on IP address 1.2.3.4:: django-admin.py runserver 1.2.3.4:7000 Serving static files with the development server ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ By default, the development server doesn't serve any static files for your site (such as CSS files, images, things under ``MEDIA_ROOT_URL`` and so forth). If you want to configure Django to serve static media, read the `serving static files`_ documentation. .. _serving static files: ../static_files/ Turning off auto-reload ~~~~~~~~~~~~~~~~~~~~~~~ To disable auto-reloading of code while the development server is running, use the ``--noreload`` option, like so:: django-admin.py runserver --noreload shell ----- Starts the Python interactive interpreter. Django will use IPython_, if it's installed. If you have IPython installed and want to force use of the "plain" Python interpreter, use the ``--plain`` option, like so:: django-admin.py shell --plain .. _IPython: http://ipython.scipy.org/ sql [appname appname ...] ------------------------- Prints the CREATE TABLE SQL statements for the given appnames. sqlall [appname appname ...] ---------------------------- Prints the CREATE TABLE and initial-data SQL statements for the given appnames. Refer to the description of ``sqlinitialdata`` for an explanation of how to specify initial data. sqlclear [appname appname ...] -------------------------------------- Prints the DROP TABLE SQL statements for the given appnames. sqlcustom [appname appname ...] ------------------------------- Prints the custom SQL statements for the given appnames. For each model in each specified app, this command looks for the file ``/sql/.sql``, where ```` is the given appname and ```` is the model's name in lowercase. For example, if you have an app ``news`` that includes a ``Story`` model, ``sqlcustom`` will attempt to read a file ``news/sql/story.sql`` and append it to the output of this command. Each of the SQL files, if given, is expected to contain valid SQL. The SQL files are piped directly into the database after all of the models' table-creation statements have been executed. Use this SQL hook to make any table modifications, or insert any SQL functions into the database. Note that the order in which the SQL files are processed is undefined. sqlindexes [appname appname ...] ---------------------------------------- Prints the CREATE INDEX SQL statements for the given appnames. sqlreset [appname appname ...] -------------------------------------- Prints the DROP TABLE SQL, then the CREATE TABLE SQL, for the given appnames. sqlsequencereset [appname appname ...] ---------------------------------------------- Prints the SQL statements for resetting sequences for the given appnames. See http://simon.incutio.com/archive/2004/04/21/postgres for more information. startapp [appname] ------------------ Creates a Django app directory structure for the given app name in the current directory. startproject [projectname] -------------------------- Creates a Django project directory structure for the given project name in the current directory. syncdb ------ Creates the database tables for all apps in ``INSTALLED_APPS`` whose tables have not already been created. Use this command when you've added new applications to your project and want to install them in the database. This includes any apps shipped with Django that might be in ``INSTALLED_APPS`` by default. When you start a new project, run this command to install the default apps. If you're installing the ``django.contrib.auth`` application, ``syncdb`` will give you the option of creating a superuser immediately. ``syncdb`` will also search for and install any fixture named ``initial_data``. See the documentation for ``loaddata`` for details on the specification of fixture data files. test ---- Discover and run tests for all installed models. See `Testing Django applications`_ for more information. .. _testing django applications: ../testing/ validate -------- Validates all installed models (according to the ``INSTALLED_APPS`` setting) and prints validation errors to standard output. Available options ================= --settings ---------- Example usage:: django-admin.py syncdb --settings=mysite.settings Explicitly specifies the settings module to use. The settings module should be in Python package syntax, e.g. ``mysite.settings``. If this isn't provided, ``django-admin.py`` will use the ``DJANGO_SETTINGS_MODULE`` environment variable. Note that this option is unnecessary in ``manage.py``, because it takes care of setting ``DJANGO_SETTINGS_MODULE`` for you. --pythonpath ------------ Example usage:: django-admin.py syncdb --pythonpath='/home/djangoprojects/myproject' Adds the given filesystem path to the Python `import search path`_. If this isn't provided, ``django-admin.py`` will use the ``PYTHONPATH`` environment variable. Note that this option is unnecessary in ``manage.py``, because it takes care of setting the Python path for you. .. _import search path: http://diveintopython.org/getting_to_know_python/everything_is_an_object.html --format -------- Example usage:: django-admin.py dumpdata --format=xml Specifies the output format that will be used. The name provided must be the name of a registered serializer. --help ------ Displays a help message that includes a terse list of all available actions and options. --indent -------- Example usage:: django-admin.py dumpdata --indent=4 Specifies the number of spaces that will be used for indentation when pretty-printing output. By default, output will *not* be pretty-printed. Pretty-printing will only be enabled if the indent option is provided. --noinput --------- Inform django-admin that the user should NOT be prompted for any input. Useful if the django-admin script will be executed as an unattended, automated script. --noreload ---------- Disable the use of the auto-reloader when running the development server. --version --------- Displays the current Django version. Example output:: 0.9.1 0.9.1 (SVN) --verbosity ----------- Example usage:: django-admin.py syncdb --verbosity=2 Verbosity determines the amount of notification and debug information that will be printed to the console. '0' is no output, '1' is normal output, and `2` is verbose output. --adminmedia ------------ Example usage:: django-admin.py --adminmedia=/tmp/new-admin-style/ Tells Django where to find the various CSS and JavaScript files for the admin interface when running the development server. Normally these files are served out of the Django source tree, but because some designers customize these files for their site, this option allows you to test against custom versions. Extra niceties ============== Syntax coloring --------------- The ``django-admin.py`` / ``manage.py`` commands that output SQL to standard output will use pretty color-coded output if your terminal supports ANSI-colored output. It won't use the color codes if you're piping the command's output to another program. Bash completion --------------- If you use the Bash shell, consider installing the Django bash completion script, which lives in ``extras/django_bash_completion`` in the Django distribution. It enables tab-completion of ``django-admin.py`` and ``manage.py`` commands, so you can, for instance... * Type ``django-admin.py``. * Press [TAB] to see all available options. * Type ``sql``, then [TAB], to see all available options whose names start with ``sql``.
