I have registered my signal with the callback using the @receiver decorator
@receiver
@receiver(post_save, sender=User, dispatch_uid=\'ARandomUniqueString
I have put the from app.signals import * code in __init__.py
from app.signals import *
__init__.py
You should not put anything in your __init__.py file.
If you remove this from __init__.py, and add it to the bottom of your models.py, it should solve your problem.
models.py
You should also avoid "blind" imports from foo import *
from foo import *
