'Auto-discover task modules.
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 (str): The name of the module to find.  Defaults
to "tasks": meaning "look for \'module.tasks\' for every
module in ``packages``."
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.'

def autodiscover_tasks(self, packages=None, related_name=u'tasks', force=False):

    if force:
        return self._autodiscover_tasks(packages, related_name)
    signals.import_modules.connect(starpromise(self._autodiscover_tasks, packages, related_name), weak=False, sender=self)
