django-admin and manage.py
==========================
``django-admin`` is Django's command-line utility for administrative tasks.
This document outlines all it can do.
.. versionchanged:: 1.7
Prior to Django 1.7, ``django-admin`` was only installed as
``django-admin.py``.
In addition, ``manage.py`` is automatically created in each Django project.
``manage.py`` is a thin wrapper around ``django-admin`` that takes care of
two things for you before delegating to ``django-admin``:
* It puts your project's package on ``sys.path``.
* It sets the :envvar:`DJANGO_SETTINGS_MODULE` environment variable so that
it points to your project's ``settings.py`` file.
* It calls :func:`django.setup()` to initialize various internals of Django.
.. versionadded:: 1.7
:func:`django.setup()` didn't exist in previous versions of Django.
The ``django-admin`` 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.exe`` 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`` than ``django-admin``. If you need to switch between multiple
Django settings files, use ``django-admin`` with
:envvar:`DJANGO_SETTINGS_MODULE` or the :djadminopt:`--settings` command line
option.
The command-line examples throughout this document use ``django-admin`` to
be consistent, but any example can use ``manage.py`` just as well.
Usage
=====
.. code-block:: bash
$ django-admin <command> [options]
$ manage.py <command> [options]
``command`` should be one of the commands listed in this document.
``options``, which is optional, should be zero or more of the options available
for the given command.
Getting runtime help
--------------------
.. django-admin:: help
Run ``django-admin help`` to display usage information and a list of the
commands provided by each application.
Run ``django-admin help --commands`` to display a list of all available
commands.
Run ``django-admin help <command>`` to display a description of the given
command and a list of its available options.
App names
---------
Many commands take a list of "app names." An "app name" is the basename of
the package containing your models. For example, if your :setting:`INSTALLED_APPS`
contains the string ``'mysite.blog'``, the app name is ``blog``.
Determining the version
-----------------------
.. django-admin:: version
Run ``django-admin version`` to display the current Django version.
The output follows the schema described in :pep:`386`::
1.4.dev17026
1.4a1
1.4
Displaying debug output
-----------------------
Use :djadminopt:`--verbosity` to specify the amount of notification and debug information
that ``django-admin`` should print to the console. For more details, see the
documentation for the :djadminopt:`--verbosity` option.
Available commands
==================
check <appname appname ...>
---------------------------
.. django-admin:: check
.. versionchanged:: 1.7
Uses the :doc:`system check framework </ref/checks>` to inspect
the entire Django project for common problems.
The system check framework will confirm that there aren't any problems with
your installed models or your admin registrations. It will also provide warnings
of common compatibility problems introduced by upgrading Django to a new version.
Custom checks may be introduced by other libraries and applications.
By default, all apps will be checked. You can check a subset of apps by providing
a list of app labels as arguments::
python manage.py check auth admin myapp
If you do not specify any app, all apps will be checked.
.. django-admin-option:: --tag <tagname>
The :doc:`system check framework </ref/checks>` performs many different
types of checks. These check types are categorized with tags. You can use these tags
to restrict the checks performed to just those in a particular category. For example,
to perform only security and compatibility checks, you would run::
python manage.py check --tag security --tag compatibility
.. django-admin-option:: --list-tags
List all available tags.
compilemessages
---------------
.. django-admin:: compilemessages
Compiles .po files created by :djadmin:`makemessages` to .mo files for use with
the builtin gettext support. See :doc:`/topics/i18n/index`.
Use the :djadminopt:`--locale` option (or its shorter version ``-l``) to
specify the locale(s) to process. If not provided, all locales are processed.
.. versionadded:: 1.8
Use the :djadminopt:`--exclude` option (or its shorter version ``-x``) to
specify the locale(s) to exclude from processing. If not provided, no locales
are excluded.
Example usage::
django-admin compilemessages --locale=pt_BR
django-admin compilemessages --locale=pt_BR --locale=fr
django-admin compilemessages -l pt_BR
django-admin compilemessages -l pt_BR -l fr
django-admin compilemessages --exclude=pt_BR
django-admin compilemessages --exclude=pt_BR --exclude=fr
django-admin compilemessages -x pt_BR
django-admin compilemessages -x pt_BR -x fr
createcachetable
----------------
.. django-admin:: createcachetable
Creates the cache tables for use with the database cache backend. See
:doc:`/topics/cache` for more information.
The :djadminopt:`--database` option can be used to specify the database
onto which the cachetable will be installed.
.. versionchanged:: 1.7
It is no longer necessary to provide the cache table name or the
:djadminopt:`--database` option. Django takes this information from your
settings file. If you have configured multiple caches or multiple databases,
all cache tables are created.
dbshell
-------
.. django-admin:: dbshell
Runs the command-line client for the database engine specified in your
``ENGINE`` setting, with the connection parameters specified in your
:setting:`USER`, :setting:`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.
The :djadminopt:`--database` option can be used to specify the database
onto which to open a shell.
diffsettings
------------
.. django-admin:: 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 :setting:`ROOT_URLCONF`, so
:setting:`ROOT_URLCONF` is followed by ``"###"`` in the output of
``diffsettings``.
The :djadminopt:`--all` option may be provided to display all settings, even
if they have Django's default value. Such settings are prefixed by ``"###"``.
dumpdata <app_label app_label app_label.Model ...>
--------------------------------------------------
.. django-admin:: dumpdata
Outputs to standard output all data in the database associated with the named
application(s).
If no application name is provided, all installed applications will be dumped.
The output of ``dumpdata`` can be used as input for :djadmin:`loaddata`.
Note that ``dumpdata`` uses the default manager on the model for selecting the
records to dump. If you're using a :ref:`custom manager <custom-managers>` as
the default manager and it filters some of the available records, not all of the
objects will be dumped.
The :djadminopt:`--all` option may be provided to specify that
``dumpdata`` should use Django's base manager, dumping records which
might otherwise be filtered or modified by a custom manager.
.. django-admin-option:: --format <fmt>
By default, ``dumpdata`` will format its output in JSON, but you can use the
``--format`` option to specify another format. Currently supported formats
are listed in :ref:`serialization-formats`.
.. django-admin-option:: --indent <num>
By default, ``dumpdata`` will output all data on a single line. This isn't
easy for humans to read, so you can use the ``--indent`` option to
pretty-print the output with a number of indentation spaces.
The :djadminopt:`--exclude` option may be provided to prevent specific
applications or models (specified as in the form of ``app_label.ModelName``)
from being dumped. If you specify a model name to ``dumpdata``, the dumped
output will be restricted to that model, rather than the entire application.
You can also mix application names and model names.
The :djadminopt:`--database` option can be used to specify the database
from which data will be dumped.
.. django-admin-option:: --natural-foreign
.. versionadded:: 1.7
When this option is specified, Django will use the ``natural_key()`` model
method to serialize any foreign key and many-to-many relationship to objects of
the type that defines the method. If you are dumping ``contrib.auth``
``Permission`` objects or ``contrib.contenttypes`` ``ContentType`` objects, you
should probably be using this flag. See the :ref:`natural keys
<topics-serialization-natural-keys>` documentation for more details on this
and the next option.
.. django-admin-option:: --natural-primary
.. versionadded:: 1.7
When this option is specified, Django will not provide the primary key in the
serialized data of this object since it can be calculated during
deserialization.
.. django-admin-option:: --natural
.. deprecated:: 1.7
Equivalent to the :djadminopt:`--natural-foreign` option; use that instead.
Use :ref:`natural keys <topics-serialization-natural-keys>` to represent
any foreign key and many-to-many relationship with a model that provides
a natural key definition.
.. django-admin-option:: --pks
By default, ``dumpdata`` will output all the records of the model, but
you can use the ``--pks`` option to specify a comma separated list of
primary keys on which to filter. This is only available when dumping
one model.
.. django-admin-option:: --output
.. versionadded:: 1.8
By default ``dumpdata`` will output all the serialized data to standard output.
This options allows to specify the file to which the data is to be written.
flush
-----
.. django-admin:: flush
Removes all data from the database, re-executes any post-synchronization
handlers, and reinstalls any initial data fixtures.
The :djadminopt:`--noinput` option may be provided to suppress all user
prompts.
The :djadminopt:`--database` option may be used to specify the database
to flush.
``--no-initial-data``
~~~~~~~~~~~~~~~~~~~~~
Use ``--no-initial-data`` to avoid loading the initial_data fixture.
inspectdb
---------
.. django-admin:: inspectdb
Introspects the database tables in the database pointed-to by the
:setting:`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.
By default, ``inspectdb`` creates unmanaged models. That is, ``managed = False``
in the model's ``Meta`` class tells Django not to manage each table's creation,
modification, and deletion. If you do want to allow Django to manage the
table's lifecycle, you'll need to change the
:attr:`~django.db.models.Options.managed` option to ``True`` (or simply remove
it because ``True`` is its default value).
The :djadminopt:`--database` option may be used to specify the
database to introspect.
loaddata <fixture fixture ...>
------------------------------
.. django-admin:: loaddata
Searches for and loads the contents of the named fixture into the database.
The :djadminopt:`--database` option can be used to specify the database
onto which the data will be loaded.
.. django-admin-option:: --ignorenonexistent
The :djadminopt:`--ignorenonexistent` option can be used to ignore fields and
models that may have been removed since the fixture was originally generated.
.. versionchanged:: 1.7
``--app`` was added.
.. versionchanged:: 1.8
``--ignorenonexistent`` also ignores non-existent models.
.. django-admin-option:: --app
The :djadminopt:`--app` option can be used to specify a single app to look
for fixtures in rather than looking through all apps.
What's a "fixture"?
~~~~~~~~~~~~~~~~~~~
A *fixture* is a collection of files that contain the serialized contents of
the database. Each fixture has a unique name, and 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 :setting:`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 loaddata mydata.json
would only load JSON fixtures called ``mydata``. The fixture extension
must correspond to the registered name of a
:ref:`serializer <serialization-formats>` (e.g., ``json`` or ``xml``).
If you omit the extensions, Django will search all available fixture types
for a matching fixture. For example::
django-admin 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.
The fixtures that are named can include directory components. These
directories will be included in the search path. For example::
django-admin loaddata foo/bar/mydata.json
would search ``<app_label>/fixtures/foo/bar/mydata.json`` for each installed
application, ``<dirname>/foo/bar/mydata.json`` for each directory in
:setting:`FIXTURE_DIRS`, and the literal path ``foo/bar/mydata.json``.
When fixture files are processed, the data is saved to the database as is.
Model defined :meth:`~django.db.models.Model.save` methods are not called, and
any :data:`~django.db.models.signals.pre_save` or
:data:`~django.db.models.signals.post_save` signals will be called with
``raw=True`` since the instance only contains attributes that are local to the
model. You may, for example, want to disable handlers that access
related fields that aren't present during fixture loading and would otherwise
raise an exception::
from django.db.models.signals import post_save
from .models import MyModel
def my_handler(**kwargs):
# disable the handler during fixture loading
if kwargs['raw']:
return
...
post_save.connect(my_handler, sender=MyModel)
You could also write a simple decorator to encapsulate this logic::
from functools import wraps
def disable_for_loaddata(signal_handler):
"""
Decorator that turns off signal handlers when loading fixture data.
"""
@wraps(signal_handler)
def wrapper(*args, **kwargs):
if kwargs['raw']:
return
signal_handler(*args, **kwargs)
return wrapper
@disable_for_loaddata
def my_handler(**kwargs):
...
Just be aware that this logic will disable the signals whenever fixtures are
deserialized, not just during ``loaddata``.
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 :djadmin:`dumpdata` command can be used to generate input for ``loaddata``.
Compressed fixtures
~~~~~~~~~~~~~~~~~~~
Fixtures may be compressed in ``zip``, ``gz``, or ``bz2`` format. For example::
django-admin loaddata mydata.json
would look for any of ``mydata.json``, ``mydata.json.zip``,
``mydata.json.gz``, or ``mydata.json.bz2``. The first file contained within a
zip-compressed archive is used.
Note that if two fixtures with the same name but different
fixture type are discovered (for example, if ``mydata.json`` and
``mydata.xml.gz`` 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.
.. admonition:: MySQL with MyISAM and fixtures
The MyISAM storage engine of MySQL doesn't support transactions or
constraints, so if you use MyISAM, you won't get validation of fixture
data, or a rollback if multiple transaction files are found.
Database-specific fixtures
~~~~~~~~~~~~~~~~~~~~~~~~~~
If you're in a multi-database setup, you might have fixture data that
you want to load onto one database, but not onto another. In this
situation, you can add database identifier into the names of your fixtures.
For example, if your :setting:`DATABASES` setting has a 'master' database
defined, name the fixture ``mydata.master.json`` or
``mydata.master.json.gz`` and the fixture will only be loaded when you
specify you want to load data into the ``master`` database.
makemessages
------------
.. django-admin:: makemessages
Runs over the entire source tree of the current directory and pulls out all
strings marked for translation. It creates (or updates) a message file in the
conf/locale (in the Django tree) or locale (for project and application)
directory. After making changes to the messages files you need to compile them
with :djadmin:`compilemessages` for use with the builtin gettext support. See
the :ref:`i18n documentation <how-to-create-language-files>` for details.
.. django-admin-option:: --all
Use the ``--all`` or ``-a`` option to update the message files for all
available languages.
Example usage::
django-admin makemessages --all
.. django-admin-option:: --extension
Use the ``--extension`` or ``-e`` option to specify a list of file extensions
to examine (default: ".html", ".txt").
Example usage::
django-admin makemessages --locale=de --extension xhtml
Separate multiple extensions with commas or use -e or --extension multiple times::
django-admin makemessages --locale=de --extension=html,txt --extension xml
Use the :djadminopt:`--locale` option (or its shorter version ``-l``) to
specify the locale(s) to process.
.. versionadded:: 1.8
Use the :djadminopt:`--exclude` option (or its shorter version ``-x``) to
specify the locale(s) to exclude from processing. If not provided, no locales
are excluded.
Example usage::
django-admin makemessages --locale=pt_BR
django-admin makemessages --locale=pt_BR --locale=fr
django-admin makemessages -l pt_BR
django-admin makemessages -l pt_BR -l fr
django-admin makemessages --exclude=pt_BR
django-admin makemessages --exclude=pt_BR --exclude=fr
django-admin makemessages -x pt_BR
django-admin makemessages -x pt_BR -x fr
.. versionchanged:: 1.7
Added the ``--previous`` option to the ``msgmerge`` command when merging
with existing po files.
.. django-admin-option:: --domain
Use the ``--domain`` or ``-d`` option to change the domain of the messages files.
Currently supported:
* ``django`` for all ``*.py``, ``*.html`` and ``*.txt`` files (default)
* ``djangojs`` for ``*.js`` files
.. django-admin-option:: --symlinks
Use the ``--symlinks`` or ``-s`` option to follow symlinks to directories when
looking for new translation strings.
Example usage::
django-admin makemessages --locale=de --symlinks
.. django-admin-option:: --ignore
Use the ``--ignore`` or ``-i`` option to ignore files or directories matching
the given :mod:`glob`-style pattern. Use multiple times to ignore more.
These patterns are used by default: ``'CVS'``, ``'.*'``, ``'*~'``, ``'*.pyc'``
Example usage::
django-admin makemessages --locale=en_US --ignore=apps/* --ignore=secret/*.html
.. django-admin-option:: --no-default-ignore
Use the ``--no-default-ignore`` option to disable the default values of
:djadminopt:`--ignore`.
.. django-admin-option:: --no-wrap
Use the ``--no-wrap`` option to disable breaking long message lines into
several lines in language files.
.. django-admin-option:: --no-location
Use the ``--no-location`` option to not write '``#: filename:line``’
comment lines in language files. Note that using this option makes it harder
for technically skilled translators to understand each message's context.
.. django-admin-option:: --keep-pot
Use the ``--keep-pot`` option to prevent Django from deleting the temporary
.pot files it generates before creating the .po file. This is useful for
debugging errors which may prevent the final language files from being created.
makemigrations [<app_label>]
----------------------------
.. django-admin:: makemigrations
.. versionadded:: 1.7
Creates new migrations based on the changes detected to your models.
Migrations, their relationship with apps and more are covered in depth in
:doc:`the migrations documentation</topics/migrations>`.
Providing one or more app names as arguments will limit the migrations created
to the app(s) specified and any dependencies needed (the table at the other end
of a ``ForeignKey``, for example).
The :djadminopt:`--noinput` option may be provided to suppress all user prompts.
.. django-admin-option:: --empty
The ``--empty`` option will cause ``makemigrations`` to output an empty
migration for the specified apps, for manual editing. This option is only
for advanced users and should not be used unless you are familiar with
the migration format, migration operations, and the dependencies between
your migrations.
.. django-admin-option:: --dry-run
The ``--dry-run`` option shows what migrations would be made without
actually writing any migrations files to disk. Using this option along with
``--verbosity 3`` will also show the complete migrations files that would be
written.
.. django-admin-option:: --merge
The ``--merge`` option enables fixing of migration conflicts.
migrate [<app_label> [<migrationname>]]
---------------------------------------
.. django-admin:: migrate
.. versionadded:: 1.7
Synchronizes the database state with the current set of models and migrations.
Migrations, their relationship with apps and more are covered in depth in
:doc:`the migrations documentation</topics/migrations>`.
The behavior of this command changes depending on the arguments provided:
* No arguments: All migrated apps have all of their migrations run,
and all unmigrated apps are synchronized with the database,
* ``<app_label>``: The specified app has its migrations run, up to the most
recent migration. This may involve running other apps' migrations too, due
to dependencies.
* ``<app_label> <migrationname>``: Brings the database schema to a state where it
would have just run the given migration, but no further - this may involve
unapplying migrations if you have previously migrated past the named
migration. Use the name ``zero`` to unapply all migrations for an app.
Unlike ``syncdb``, this command does not prompt you to create a superuser if
one doesn't exist (assuming you are using :mod:`django.contrib.auth`). Use
:djadmin:`createsuperuser` to do that if you wish.
.. django-admin-option:: --fake
The ``--fake`` option tells Django to mark the migrations as having been
applied or unapplied, but without actually running the SQL to change your
database schema.
This is intended for advanced users to manipulate the
current migration state directly if they're manually applying changes;
be warned that using ``--fake`` runs the risk of putting the migration state
table into a state where manual recovery will be needed to make migrations
run correctly.
.. django-admin-option:: --list, -l
The ``--list`` option will list all of the apps Django knows about, the
migrations available for each app and if they are applied or not (marked by
an ``[X]`` next to the migration name).
Apps without migrations are also included in the list, but will have
``(no migrations)`` printed under them.
runfcgi [options]
-----------------
.. django-admin:: runfcgi
.. deprecated:: 1.7
FastCGI support is deprecated and will be removed in Django 1.9.
Starts a set of FastCGI processes suitable for use with any Web server that
supports the FastCGI protocol. See the :doc:`FastCGI deployment documentation
</howto/deployment/fastcgi>` for details. Requires the Python FastCGI module from
`flup`_.
Internally, this wraps the WSGI application object specified by the
:setting:`WSGI_APPLICATION` setting.
.. _flup: http://www.saddi.com/software/flup/
The options accepted by this command are passed to the FastCGI library and
don't use the ``'--'`` prefix as is usual for other Django management commands.
.. django-admin-option:: protocol
``protocol=PROTOCOL``
Protocol to use. *PROTOCOL* can be ``fcgi``, ``scgi``, ``ajp``, etc.
(default is ``fcgi``)
.. django-admin-option:: host
``host=HOSTNAME``
Hostname to listen on.
.. django-admin-option:: port
``port=PORTNUM``
Port to listen on.
.. django-admin-option:: socket
``socket=FILE``
UNIX socket to listen on.
.. django-admin-option:: method
``method=IMPL``
Possible values: ``prefork`` or ``threaded`` (default ``prefork``)
.. django-admin-option:: maxrequests
``maxrequests=NUMBER``
Number of requests a child handles before it is killed and a new child is
forked (0 means no limit).
.. django-admin-option:: maxspare
``maxspare=NUMBER``
Max number of spare processes / threads.
.. django-admin-option:: minspare
``minspare=NUMBER``
Min number of spare processes / threads.
.. django-admin-option:: maxchildren
``maxchildren=NUMBER``
Hard limit number of processes / threads.
.. django-admin-option:: daemonize
``daemonize=BOOL``
Whether to detach from terminal.
.. django-admin-option:: pidfile
``pidfile=FILE``
Write the spawned process-id to file *FILE*.
.. django-admin-option:: workdir
``workdir=DIRECTORY``
Change to directory *DIRECTORY* when daemonizing.
.. django-admin-option:: debug
``debug=BOOL``
Set to true to enable flup tracebacks.
.. django-admin-option:: outlog
``outlog=FILE``
Write stdout to the *FILE* file.
.. django-admin-option:: errlog
``errlog=FILE``
Write stderr to the *FILE* file.
.. django-admin-option:: umask
``umask=UMASK``
Umask to use when daemonizing. The value is interpreted as an octal number
(default value is ``0o22``).
Example usage::
django-admin runfcgi socket=/tmp/fcgi.sock method=prefork daemonize=true \
pidfile=/var/run/django-fcgi.pid
Run a FastCGI server as a daemon and write the spawned PID in a file.
runserver [port or address:port]
--------------------------------
.. django-admin:: runserver
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).
This server uses the WSGI application object specified by the
:setting:`WSGI_APPLICATION` setting.
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.
However, some actions like adding files don't trigger a restart, so you'll
have to restart the server in these cases.
.. versionchanged:: 1.7
Compiling translation files now also restarts the development server.
If you are using Linux and install `pyinotify`_, kernel signals will be used to
autoreload the server (rather than polling file modification timestamps each
second). This offers better scaling to large projects, reduction in response
time to code modification, more robust change detection, and battery usage
reduction.
.. _pyinotify: https://pypi.python.org/pypi/pyinotify/
.. versionadded:: 1.7
``pyinotify`` support was added.
When you start the server, and each time you change Python code while the
server is running, the server will check your entire Django project for errors (see
the :djadmin:`check` command). If any errors are found, they will be printed
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 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`` or ``::`` (with IPv6 enabled).
You can provide an IPv6 address surrounded by brackets
(e.g. ``[200a::1]:8000``). This will automatically enable IPv6 support.
A hostname containing ASCII-only characters can also be used.
If the :doc:`staticfiles</ref/contrib/staticfiles>` contrib app is enabled
(default in new projects) the :djadmin:`runserver` command will be overridden
with its own :ref:`runserver<staticfiles-runserver>` command.
.. django-admin-option:: --noreload
Use the ``--noreload`` option to disable the use of the auto-reloader. This
means any Python code changes you make while the server is running will *not*
take effect if the particular Python modules have already been loaded into
memory.
Example usage::
django-admin runserver --noreload
.. django-admin-option:: --nothreading
The development server is multithreaded by default. Use the ``--nothreading``
option to disable the use of threading in the development server.
.. django-admin-option:: --ipv6, -6
Use the ``--ipv6`` (or shorter ``-6``) option to tell Django to use IPv6 for
the development server. This changes the default IP address from
``127.0.0.1`` to ``::1``.
Example usage::
django-admin runserver --ipv6
Examples of using different ports and addresses
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Port 8000 on IP address ``127.0.0.1``::
django-admin runserver
Port 8000 on IP address ``1.2.3.4``::
django-admin runserver 1.2.3.4:8000
Port 7000 on IP address ``127.0.0.1``::
django-admin runserver 7000
Port 7000 on IP address ``1.2.3.4``::
django-admin runserver 1.2.3.4:7000
Port 8000 on IPv6 address ``::1``::
django-admin runserver -6
Port 7000 on IPv6 address ``::1``::
django-admin runserver -6 7000
Port 7000 on IPv6 address ``2001:0db8:1234:5678::9``::
django-admin runserver [2001:0db8:1234:5678::9]:7000
Port 8000 on IPv4 address of host ``localhost``::
django-admin runserver localhost:8000
Port 8000 on IPv6 address of host ``localhost``::
django-admin runserver -6 localhost:8000
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 :setting:`MEDIA_URL` and so forth). If
you want to configure Django to serve static media, read
:doc:`/howto/static-files/index`.
shell
-----
.. django-admin:: shell
Starts the Python interactive interpreter.
Django will use IPython_ or bpython_ if either is installed. If you have a
rich shell installed but want to force use of the "plain" Python interpreter,
use the ``--plain`` option, like so::
django-admin shell --plain
If you would like to specify either IPython or bpython as your interpreter if
you have both installed you can specify an alternative interpreter interface
with the ``-i`` or ``--interface`` options like so:
IPython::
django-admin shell -i ipython
django-admin shell --interface ipython
bpython::
django-admin shell -i bpython
django-admin shell --interface bpython
.. _IPython: http://ipython.scipy.org/
.. _bpython: http://bpython-interpreter.org/
When the "plain" Python interactive interpreter starts (be it because
``--plain`` was specified or because no other interactive interface is
available) it reads the script pointed to by the :envvar:`PYTHONSTARTUP`
environment variable and the ``~/.pythonrc.py`` script. If you don't wish this
behavior you can use the ``--no-startup`` option. e.g.::
django-admin shell --plain --no-startup
sql <app_label app_label ...>
-----------------------------
.. django-admin:: sql
Prints the CREATE TABLE SQL statements for the given app name(s).
The :djadminopt:`--database` option can be used to specify the database for
which to print the SQL.
sqlall <app_label app_label ...>
--------------------------------
.. django-admin:: sqlall
Prints the CREATE TABLE and initial-data SQL statements for the given app name(s).
Refer to the description of :djadmin:`sqlcustom` for an explanation of how to
specify initial data.
The :djadminopt:`--database` option can be used to specify the database for
which to print the SQL.
.. versionchanged:: 1.7
The ``sql*`` management commands now respect the ``allow_migrate()`` method
of :setting:`DATABASE_ROUTERS`. If you have models synced to non-default
databases, use the :djadminopt:`--database` flag to get SQL for those
models (previously they would always be included in the output).
sqlclear <app_label app_label ...>
----------------------------------
.. django-admin:: sqlclear
Prints the DROP TABLE SQL statements for the given app name(s).
The :djadminopt:`--database` option can be used to specify the database for
which to print the SQL.
sqlcustom <app_label app_label ...>
-----------------------------------
.. django-admin:: sqlcustom
Prints the custom SQL statements for the given app name(s).
For each model in each specified app, this command looks for the file
``<app_label>/sql/<modelname>.sql``, where ``<app_label>`` is the given app
name and ``<modelname>`` 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.
The :djadminopt:`--database` option can be used to specify the database for
which to print the SQL.
sqldropindexes <app_label app_label ...>
----------------------------------------
.. django-admin:: sqldropindexes
Prints the DROP INDEX SQL statements for the given app name(s).
The :djadminopt:`--database` option can be used to specify the database for
which to print the SQL.
sqlflush
--------
.. django-admin:: sqlflush
Prints the SQL statements that would be executed for the :djadmin:`flush`
command.
The :djadminopt:`--database` option can be used to specify the database for
which to print the SQL.
sqlindexes <app_label app_label ...>
------------------------------------
.. django-admin:: sqlindexes
Prints the CREATE INDEX SQL statements for the given app name(s).
The :djadminopt:`--database` option can be used to specify the database for
which to print the SQL.
sqlmigrate <app_label> <migrationname>
--------------------------------------
.. django-admin:: sqlmigrate
Prints the SQL for the named migration. This requires an active database
connection, which it will use to resolve constraint names; this means you must
generate the SQL against a copy of the database you wish to later apply it on.
The :djadminopt:`--database` option can be used to specify the database for
which to generate the SQL.
.. django-admin-option:: --backwards
By default, the SQL created is for running the migration in the forwards
direction. Pass ``--backwards`` to generate the SQL for
unapplying the migration instead.
sqlsequencereset <app_label app_label ...>
------------------------------------------
.. django-admin:: sqlsequencereset
Prints the SQL statements for resetting sequences for the given app name(s).
Sequences are indexes used by some database engines to track the next available
number for automatically incremented fields.
Use this command to generate SQL which will fix cases where a sequence is out
of sync with its automatically incremented field data.
The :djadminopt:`--database` option can be used to specify the database for
which to print the SQL.
squashmigrations <app_label> <migration_name>
---------------------------------------------
.. django-admin:: squashmigrations
Squashes the migrations for ``app_label`` up to and including ``migration_name``
down into fewer migrations, if possible. The resulting squashed migrations
can live alongside the unsquashed ones safely. For more information,
please read :ref:`migration-squashing`.
.. django-admin-option:: --no-optimize
By default, Django will try to optimize the operations in your migrations
to reduce the size of the resulting file. Pass ``--no-optimize`` if this
process is failing for you or creating incorrect migrations, though please
also file a Django bug report about the behavior, as optimization is meant
to be safe.
startapp <app_label> [destination]
----------------------------------
.. django-admin:: startapp
Creates a Django app directory structure for the given app name in the current
directory or the given destination.
By default the directory created contains a ``models.py`` file and other app
template files. (See the `source`_ for more details.) If only the app
name is given, the app directory will be created in the current working
directory.
If the optional destination is provided, Django will use that existing
directory rather than creating a new one. You can use '.' to denote the current
working directory.
For example::
django-admin startapp myapp /Users/jezdez/Code/myapp
.. _custom-app-and-project-templates:
.. django-admin-option:: --template
With the ``--template`` option, you can use a custom app template by providing
either the path to a directory with the app template file, or a path to a
compressed file (``.tar.gz``, ``.tar.bz2``, ``.tgz``, ``.tbz``, ``.zip``)
containing the app template files.
For example, this would look for an app template in the given directory when
creating the ``myapp`` app::
django-admin startapp --template=/Users/jezdez/Code/my_app_template myapp
Django will also accept URLs (``http``, ``https``, ``ftp``) to compressed
archives with the app template files, downloading and extracting them on the
fly.
For example, taking advantage of Github's feature to expose repositories as
zip files, you can use a URL like::
django-admin startapp --template=https://github.com/githubuser/django-app-template/archive/master.zip myapp
When Django copies the app template files, it also renders certain files
through the template engine: the files whose extensions match the
``--extension`` option (``py`` by default) and the files whose names are passed
with the ``--name`` option. The :class:`template context
<django.template.Context>` used is:
- Any option passed to the ``startapp`` command (among the command's supported
options)
- ``app_name`` -- the app name as passed to the command
- ``app_directory`` -- the full path of the newly created app
- ``docs_version`` -- the version of the documentation: ``'dev'`` or ``'1.x'``
.. _render_warning:
.. warning::
When the app template files are rendered with the Django template
engine (by default all ``*.py`` files), Django will also replace all
stray template variables contained. For example, if one of the Python files
contains a docstring explaining a particular feature related
to template rendering, it might result in an incorrect example.
To work around this problem, you can use the :ttag:`templatetag`
templatetag to "escape" the various parts of the template syntax.
.. _source: https://github.com/django/django/tree/master/django/conf/app_template/
startproject <projectname> [destination]
----------------------------------------
.. django-admin:: startproject
Creates a Django project directory structure for the given project name in
the current directory or the given destination.
By default, the new directory contains ``manage.py`` and a project package
(containing a ``settings.py`` and other files). See the `template source`_ for
details.
If only the project name is given, both the project directory and project
package will be named ``<projectname>`` and the project directory
will be created in the current working directory.
If the optional destination is provided, Django will use that existing
directory as the project directory, and create ``manage.py`` and the project
package within it. Use '.' to denote the current working directory.
For example::
django-admin startproject myproject /Users/jezdez/Code/myproject_repo
As with the :djadmin:`startapp` command, the ``--template`` option lets you
specify a directory, file path or URL of a custom project template. See the
:djadmin:`startapp` documentation for details of supported project template
formats.
For example, this would look for a project template in the given directory
when creating the ``myproject`` project::
django-admin startproject --template=/Users/jezdez/Code/my_project_template myproject
Django will also accept URLs (``http``, ``https``, ``ftp``) to compressed
archives with the project template files, downloading and extracting them on the
fly.
For example, taking advantage of Github's feature to expose repositories as
zip files, you can use a URL like::
django-admin startproject --template=https://github.com/githubuser/django-project-template/archive/master.zip myproject
When Django copies the project template files, it also renders certain files
through the template engine: the files whose extensions match the
``--extension`` option (``py`` by default) and the files whose names are passed
with the ``--name`` option. The :class:`template context
<django.template.Context>` used is:
- Any option passed to the ``startproject`` command (among the command's
supported options)
- ``project_name`` -- the project name as passed to the command
- ``project_directory`` -- the full path of the newly created project
- ``secret_key`` -- a random key for the :setting:`SECRET_KEY` setting
- ``docs_version`` -- the version of the documentation: ``'dev'`` or ``'1.x'``
Please also see the :ref:`rendering warning <render_warning>` as mentioned
for :djadmin:`startapp`.
.. _`template source`: https://github.com/django/django/tree/master/django/conf/project_template/
syncdb
------
.. django-admin:: syncdb
.. deprecated:: 1.7
This command has been deprecated in favor of the :djadmin:`migrate`
command, which performs both the old behavior as well as executing
migrations. It is now just an alias to that command.
Alias for :djadmin:`migrate`.
test <app or test identifier>
-----------------------------
.. django-admin:: test
Runs tests for all installed models. See :doc:`/topics/testing/index` for more
information.
.. django-admin-option:: --failfast
The ``--failfast`` option can be used to stop running tests and report the
failure immediately after a test fails.
.. django-admin-option:: --testrunner
The ``--testrunner`` option can be used to control the test runner class that
is used to execute tests. If this value is provided, it overrides the value
provided by the :setting:`TEST_RUNNER` setting.
.. django-admin-option:: --liveserver
The ``--liveserver`` option can be used to override the default address where
the live server (used with :class:`~django.test.LiveServerTestCase`) is
expected to run from. The default value is ``localhost:8081``.
.. django-admin-option:: --keepdb
.. versionadded:: 1.8
The ``--keepdb`` option can be used to preserve the test database between test
runs. This has the advantage of skipping both the create and destroy actions
which greatly decreases the time to run tests, especially those in a large
test suite. If the test database does not exist, it will be created on the first
run and then preserved for each subsequent run. Any unapplied migrations will also
be applied to the test database before running the test suite.
testserver <fixture fixture ...>
--------------------------------
.. django-admin:: testserver
Runs a Django development server (as in :djadmin:`runserver`) using data from
the given fixture(s).
For example, this command::
django-admin testserver mydata.json
...would perform the following steps:
1. Create a test database, as described in :ref:`the-test-database`.
2. Populate the test database with fixture data from the given fixtures.
(For more on fixtures, see the documentation for :djadmin:`loaddata` above.)
3. Runs the Django development server (as in :djadmin:`runserver`), pointed at
this newly created test database instead of your production database.
This is useful in a number of ways:
* When you're writing :doc:`unit tests </topics/testing/overview>` of how your views
act with certain fixture data, you can use ``testserver`` to interact with
the views in a Web browser, manually.
* Let's say you're developing your Django application and have a "pristine"
copy of a database that you'd like to interact with. You can dump your
database to a fixture (using the :djadmin:`dumpdata` command, explained
above), then use ``testserver`` to run your Web application with that data.
With this arrangement, you have the flexibility of messing up your data
in any way, knowing that whatever data changes you're making are only
being made to a test database.
Note that this server does *not* automatically detect changes to your Python
source code (as :djadmin:`runserver` does). It does, however, detect changes to
templates.
.. django-admin-option:: --addrport [port number or ipaddr:port]
Use ``--addrport`` to specify a different port, or IP address and port, from
the default of ``127.0.0.1:8000``. This value follows exactly the same format and
serves exactly the same function as the argument to the :djadmin:`runserver`
command.
Examples:
To run the test server on port 7000 with ``fixture1`` and ``fixture2``::
django-admin testserver --addrport 7000 fixture1 fixture2
django-admin testserver fixture1 fixture2 --addrport 7000
(The above statements are equivalent. We include both of them to demonstrate
that it doesn't matter whether the options come before or after the fixture
arguments.)
To run on 1.2.3.4:7000 with a ``test`` fixture::
django-admin testserver --addrport 1.2.3.4:7000 test
The :djadminopt:`--noinput` option may be provided to suppress all user
prompts.
validate
--------
.. django-admin:: validate
.. deprecated:: 1.7
Replaced by the :djadmin:`check` command.
Validates all installed models (according to the :setting:`INSTALLED_APPS`
setting) and prints validation errors to standard output.
Commands provided by applications
=================================
Some commands are only available when the ``django.contrib`` application that
:doc:`implements </howto/custom-management-commands>` them has been
:setting:`enabled <INSTALLED_APPS>`. This section describes them grouped by
their application.
``django.contrib.auth``
-----------------------
changepassword
~~~~~~~~~~~~~~
.. django-admin:: changepassword
This command is only available if Django's :doc:`authentication system
</topics/auth/index>` (``django.contrib.auth``) is installed.
Allows changing a user's password. It prompts you to enter twice the password of
the user given as parameter. If they both match, the new password will be
changed immediately. If you do not supply a user, the command will attempt to
change the password whose username matches the current user.
Use the ``--database`` option to specify the database to query for the user. If
it's not supplied, Django will use the ``default`` database.
Example usage::
django-admin changepassword ringo
createsuperuser
~~~~~~~~~~~~~~~
.. django-admin:: createsuperuser
This command is only available if Django's :doc:`authentication system
</topics/auth/index>` (``django.contrib.auth``) is installed.
Creates a superuser account (a user who has all permissions). This is
useful if you need to create an initial superuser account or if you need to
programmatically generate superuser accounts for your site(s).
When run interactively, this command will prompt for a password for
the new superuser account. When run non-interactively, no password
will be set, and the superuser account will not be able to log in until
a password has been manually set for it.
.. django-admin-option:: --username
.. django-admin-option:: --email
The username and email address for the new account can be supplied by
using the ``--username`` and ``--email`` arguments on the command
line. If either of those is not supplied, ``createsuperuser`` will prompt for
it when running interactively.
Use the ``--database`` option to specify the database into which the superuser
object will be saved.
.. versionadded:: 1.8
You can subclass the management command and override ``get_input_data()`` if you
want to customize data input and validation. Consult the source code for
details on the existing implementation and the method's parameters. For example,
it could be useful if you have a ``ForeignKey`` in
:attr:`~django.contrib.auth.models.CustomUser.REQUIRED_FIELDS` and want to
allow creating an instance instead of entering the primary key of an existing
instance.
``django.contrib.gis``
----------------------
ogrinspect
~~~~~~~~~~
This command is only available if :doc:`GeoDjango </ref/contrib/gis/index>`
(``django.contrib.gis``) is installed.
Please refer to its :djadmin:`description <ogrinspect>` in the GeoDjango
documentation.
``django.contrib.sessions``
---------------------------
clearsessions
~~~~~~~~~~~~~~~
.. django-admin:: clearsessions
Can be run as a cron job or directly to clean out expired sessions.
``django.contrib.sitemaps``
---------------------------
ping_google
~~~~~~~~~~~
This command is only available if the :doc:`Sitemaps framework
</ref/contrib/sitemaps>` (``django.contrib.sitemaps``) is installed.
Please refer to its :djadmin:`description <ping_google>` in the Sitemaps
documentation.
``django.contrib.staticfiles``
------------------------------
collectstatic
~~~~~~~~~~~~~
This command is only available if the :doc:`static files application
</howto/static-files/index>` (``django.contrib.staticfiles``) is installed.
Please refer to its :djadmin:`description <collectstatic>` in the
:doc:`staticfiles </ref/contrib/staticfiles>` documentation.
findstatic
~~~~~~~~~~
This command is only available if the :doc:`static files application
</howto/static-files/index>` (``django.contrib.staticfiles``) is installed.
Please refer to its :djadmin:`description <findstatic>` in the :doc:`staticfiles
</ref/contrib/staticfiles>` documentation.
Default options
===============
Although some commands may allow their own custom options, every command
allows for the following options:
.. django-admin-option:: --pythonpath
Example usage::
django-admin migrate --pythonpath='/home/djangoprojects/myproject'
Adds the given filesystem path to the Python `import search path`_. If this
isn't provided, ``django-admin`` 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://www.diveintopython.net/getting_to_know_python/everything_is_an_object.html
.. django-admin-option:: --settings
Example usage::
django-admin migrate --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`` will use the ``DJANGO_SETTINGS_MODULE`` environment
variable.
Note that this option is unnecessary in ``manage.py``, because it uses
``settings.py`` from the current project by default.
.. django-admin-option:: --traceback
Example usage::
django-admin migrate --traceback
By default, ``django-admin`` will show a simple error message whenever an
:class:`~django.core.management.CommandError` occurs, but a full stack trace
for any other exception. If you specify ``--traceback``, ``django-admin``
will also output a full stack trace when a ``CommandError`` is raised.
.. django-admin-option:: --verbosity
Example usage::
django-admin migrate --verbosity 2
Use ``--verbosity`` to specify the amount of notification and debug information
that ``django-admin`` should print to the console.
* ``0`` means no output.
* ``1`` means normal output (default).
* ``2`` means verbose output.
* ``3`` means *very* verbose output.
.. django-admin-option:: --no-color
.. versionadded:: 1.7
Example usage::
django-admin sqlall --no-color
By default, ``django-admin`` will format the output to be colorized. For
example, errors will be printed to the console in red and SQL statements will
be syntax highlighted. To prevent this and have a plain text output, pass the
``--no-color`` option when running your command.
Common options
==============
The following options are not available on every command, but they are common
to a number of commands.
.. django-admin-option:: --database
Used to specify the database on which a command will operate. If not
specified, this option will default to an alias of ``default``.
For example, to dump data from the database with the alias ``master``::
django-admin dumpdata --database=master
.. django-admin-option:: --exclude
Exclude a specific application from the applications whose contents is
output. For example, to specifically exclude the ``auth`` application from
the output of dumpdata, you would call::
django-admin dumpdata --exclude=auth
If you want to exclude multiple applications, use multiple ``--exclude``
directives::
django-admin dumpdata --exclude=auth --exclude=contenttypes
.. django-admin-option:: --locale
Use the ``--locale`` or ``-l`` option to specify the locale to process.
If not provided all locales are processed.
.. django-admin-option:: --noinput
Use the ``--noinput`` option to suppress all user prompting, such as "Are
you sure?" confirmation messages. This is useful if ``django-admin`` is
being executed as an unattended, automated script.
Extra niceties
==============
.. _syntax-coloring:
Syntax coloring
---------------
The ``django-admin`` / ``manage.py`` commands 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.
Under Windows, the native console doesn't support ANSI escape sequences so by
default there is no color output. But you can install the `ANSICON`_
third-party tool, the Django commands will detect its presence and will make
use of its services to color output just like on Unix-based platforms.
The colors used for syntax highlighting can be customized. Django
ships with three color palettes:
* ``dark``, suited to terminals that show white text on a black
background. This is the default palette.
* ``light``, suited to terminals that show black text on a white
background.
* ``nocolor``, which disables syntax highlighting.
You select a palette by setting a ``DJANGO_COLORS`` environment
variable to specify the palette you want to use. For example, to
specify the ``light`` palette under a Unix or OS/X BASH shell, you
would run the following at a command prompt::
export DJANGO_COLORS="light"
You can also customize the colors that are used. Django specifies a
number of roles in which color is used:
* ``error`` - A major error.
* ``notice`` - A minor error.
* ``sql_field`` - The name of a model field in SQL.
* ``sql_coltype`` - The type of a model field in SQL.
* ``sql_keyword`` - An SQL keyword.
* ``sql_table`` - The name of a model in SQL.
* ``http_info`` - A 1XX HTTP Informational server response.
* ``http_success`` - A 2XX HTTP Success server response.
* ``http_not_modified`` - A 304 HTTP Not Modified server response.
* ``http_redirect`` - A 3XX HTTP Redirect server response other than 304.
* ``http_not_found`` - A 404 HTTP Not Found server response.
* ``http_bad_request`` - A 4XX HTTP Bad Request server response other than 404.
* ``http_server_error`` - A 5XX HTTP Server Error response.
Each of these roles can be assigned a specific foreground and
background color, from the following list:
* ``black``
* ``red``
* ``green``
* ``yellow``
* ``blue``
* ``magenta``
* ``cyan``
* ``white``
Each of these colors can then be modified by using the following
display options:
* ``bold``
* ``underscore``
* ``blink``
* ``reverse``
* ``conceal``
A color specification follows one of the following patterns:
* ``role=fg``
* ``role=fg/bg``
* ``role=fg,option,option``
* ``role=fg/bg,option,option``
where ``role`` is the name of a valid color role, ``fg`` is the
foreground color, ``bg`` is the background color and each ``option``
is one of the color modifying options. Multiple color specifications
are then separated by semicolon. For example::
export DJANGO_COLORS="error=yellow/blue,blink;notice=magenta"
would specify that errors be displayed using blinking yellow on blue,
and notices displayed using magenta. All other color roles would be
left uncolored.
Colors can also be specified by extending a base palette. If you put
a palette name in a color specification, all the colors implied by that
palette will be loaded. So::
export DJANGO_COLORS="light;error=yellow/blue,blink;notice=magenta"
would specify the use of all the colors in the light color palette,
*except* for the colors for errors and notices which would be
overridden as specified.
.. versionadded:: 1.7
Support for color-coded output from ``django-admin`` / ``manage.py``
utilities on Windows by relying on the ANSICON application was added in Django
1.7.
.. _ANSICON: http://adoxa.altervista.org/ansicon/
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`` and
``manage.py`` commands, so you can, for instance...
* Type ``django-admin``.
* Press [TAB] to see all available options.
* Type ``sql``, then [TAB], to see all available options whose names start
with ``sql``.
See :doc:`/howto/custom-management-commands` for how to add customized actions.
==========================================
Running management commands from your code
==========================================
.. _call-command:
.. function:: django.core.management.call_command(name, *args, **options)
To call a management command from code use ``call_command``.
``name``
the name of the command to call.
``*args``
a list of arguments accepted by the command.
``**options``
named options accepted on the command-line.
Examples::
from django.core import management
management.call_command('flush', verbosity=0, interactive=False)
management.call_command('loaddata', 'test_data', verbosity=0)
Note that command options that take no arguments are passed as keywords
with ``True`` or ``False``::
management.call_command('dumpdata', use_natural_keys=True)
Command options which take multiple options are passed a list::
management.call_command('dumpdata', exclude=['contenttypes', 'auth'])
Output redirection
==================
Note that you can redirect standard output and error streams as all commands
support the ``stdout`` and ``stderr`` options. For example, you could write::
with open('/tmp/command_output') as f:
management.call_command('dumpdata', stdout=f)
