See :ref:`Task options<task-options>` for a list of the
arguments that can be passed to this decorator.
Examples:
.. code-block:: python
@app.task
def refresh_feed(url):
store_feed(feedparser.parse(url))
with setting extra options:
.. code-block:: python
@app.task(exchange='feeds')
def refresh_feed(url):
return store_feed(feedparser.parse(url))
Note:
App Binding: For custom apps the task decorator will return
a proxy object, so that the act of creating the task is not
performed until the task is used or the task registry is accessed.
If you're depending on binding to be deferred, then you must
not access any attributes on the returned object until the
application is fully set up (finalized).

If the argument is a callable function then it will be regarded
as a promise, and it won't be loaded until the configuration is
actually needed.
This method can be compared to:
.. code-block:: pycon
>>> celery.conf.update(d)
with a difference that 1) no copy will be made and 2) the dict will
not be transferred when the worker spawns child processes, so
it's important that the same configuration happens at import time
when pickle restores the object on the other side.

Object is either an actual object or the name of a module to import.
Example:
>>> celery.config_from_object('myapp.celeryconfig')
>>> from myapp import celeryconfig
>>> celery.config_from_object(celeryconfig)
Arguments:
silent (bool): If true then import errors will be ignored.
force (bool): Force reading configuration immediately.
By default the configuration will be read only when required.

This will affect all application instances (a global operation).
Disables untrusted serializers and if configured to use the ``auth``
serializer will register the ``auth`` serializer with the provided
settings into the Kombu serializer registry.
Arguments:
allowed_serializers (Set[str]): List of serializer names, or
content_types that should be exempt from being disabled.
key (str): Name of private key file to use.
Defaults to the :setting:`security_key` setting.
key_password (bytes): Password to decrypt the private key.
Defaults to the :setting:`security_key_password` setting.
cert (str): Name of certificate file to use.
Defaults to the :setting:`security_certificate` setting.
store (str): Directory containing certificates.
Defaults to the :setting:`security_cert_store` setting.
digest (str): Digest algorithm used when signing messages.
Default is ``sha256``.
serializer (str): Serializer used to encode messages after
they've been signed. See :setting:`task_serializer` for
the serializers supported. Default is ``json``.

Searches a list of packages for a "tasks.py" module (or use
related_name argument).
If the name is empty, this will be delegated to fix-ups (e.g., Django).
For example if you have a directory layout like this:
.. code-block:: text
foo/__init__.py
tasks.py
models.py
bar/__init__.py
tasks.py
models.py
baz/__init__.py
models.py
Then calling ``app.autodiscover_tasks(['foo', 'bar', 'baz'])`` will
result in the modules ``foo.tasks`` and ``bar.tasks`` being imported.
Arguments:
packages (List[str]): List of packages to search.
This argument may also be a callable, in which case the
value returned is used (for lazy evaluation).
related_name (Optional[str]): The name of the module to find. Defaults
to "tasks": meaning "look for 'module.tasks' for every
module in ``packages``.". If ``None`` will only try to import
the package, i.e. "look for 'module'".
force (bool): By default this call is lazy so that the actual
auto-discovery won't happen until an application imports
the default modules. Forcing will cause the auto-discovery
to happen immediately.

Add a periodic task to beat schedule.
Celery beat store tasks based on `sig` or `name` if provided. Adding the
same signature twice make the second task override the first one. To
avoid the override, use distinct `name` for them.

App-compatible means that the class has a class attribute that
provides the default app it should use, for example:
``class Foo: app = None``.
Arguments:
Class (type): The app-compatible class to subclass.
name (str): Custom name for the target class.
attribute (str): Name of the attribute holding the app,
Default is 'app'.
reverse (str): Reverse path to this object used for pickling
purposes. For example, to get ``app.AsyncResult``,
use ``"AsyncResult"``.
keep_reduce (bool): If enabled a custom ``__reduce__``
implementation won't be provided.
