this exception (with a sensible description of the error) is the preferred way

to indicate that something has gone wrong in the execution of a command.

If a management command is called from code through :ref:`call_command

<call-command>`, it's up to you to catch the exception when needed.

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``.

* The generic views support OPTIONS requests.

* Management commands do not raise ``SystemExit`` any more when called by code

  from :ref:`call_command <call-command>`. Any exception raised by the command

  (mostly :exc:`~django.core.management.CommandError`) is propagated.

  from :func:`~django.core.management.call_command`. Any exception raised by

  the command (mostly :exc:`~django.core.management.CommandError`) is

  propagated.

  Moreover, when you output errors or messages in your custom commands, you

  should now use ``self.stdout.write('message')`` and

  introspect :class:`~django.db.models.AutoField` for MySQL and PostgreSQL

  databases.

* When calling management commands from code through :ref:`call_command

  <call-command>` and passing options, the option name can match the command

  line option name (without the initial dashes) or the final option destination

  variable name, but in either case, the resulting option received by the

  command is now always the ``dest`` name specified in the command option

  definition (as long as the command uses the new :py:mod:`argparse` module).

* When calling management commands with options using

  :func:`~django.core.management.call_command`, the option name can match the

  command line option name (without the initial dashes) or the final option

  destination variable name, but in either case, the resulting option received

  by the command is now always the ``dest`` name specified in the command

  option definition (as long as the command uses the :mod:`argparse` module).

* The :djadmin:`dbshell` command now supports MySQL's optional SSL certificate

  authority setting (``--ssl-ca``).

  class name found in the :setting:`BACKEND <CACHES-BACKEND>` key of the

  :setting:`CACHES` setting.

* By default, :ref:`call_command <call-command>` now always skips the check

  framework (unless you pass it ``skip_checks=False``).

* By default, :func:`~django.core.management.call_command` now always skips the

  check framework (unless you pass it ``skip_checks=False``).

* When iterating over lines, :class:`~django.core.files.File` now uses

  `universal newlines`_. The following are recognized as ending a line: the
