Celery Documentation, Release 3.1.19
• related_name – The name of the module to find. Defaults to “tasks”, which means
it look for “module.tasks” for every module in packages.
• force – By default this call is lazy so that the actual autodiscovery will not happen
until an application imports the default modules. Forcing will cause the autodiscovery
to happen immediately.
add_defaults(d)
Add default configuration from dict d.
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:
>>> 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.
setup_security(. . . )
Setup the message-signing serializer. 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.
