app.celery.MyCelery.add_defaults

MyCelery.add_defaults(fun)

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.
