Django signal receiving across apps -

i have main_app, , app2. main_app list of items data, , app2 has more information said items.

main_app isn't supposed know app2, app2 can import main_app.

within main_app/signals.py, have

import django.dispatch mysignal = django.dispatch.signal(providing_args=['uid']) 

in main_app/views.py, have view renders various main_templates, containing details of item, view editing, , 1 submitting said edited data. idea signal sent when each of called and, app2 receives this. main_template uses "with" call template2 , app's information.

in app2/processes.py have following:

import django.dispatch django.dispatch import receiver import models main_app.signals import mysignal, (mysignal2, etc) 

then each method, have

@receiver(mysignal) def foo(sender, **kwargs) etc 

ok... so, in main_app/views.py, if have line:

from app2.processes import mysignal, mysignal2 etc 

everything works smoothly. want remove reliance on app2 in main_app. far concerned, app2 importing these signals main_app/signals.py. if try rid of above line , put following main_app/views.py

from main_app.processes import mysignal, my... 

it doesn't work...i don't error data app2 doesn't render template, , don't see why....any ideas?

your signal receivers in app2 not registered. simple check: put raise exception("i imported!"); first line in app2/processes.py. never see exception. have make sure signal receivers being registered. can import app2.processes somewhere django look. example in app2/models.py.
