Django post save signal getting called twice despite uid

Question

I have registered my signal with the callback using the @receiver decorator

@receiver(post_save, sender=User, dispatch_uid=\'ARandomUniqueString         


        

Answer 1

I had the same problem with post_save and also post_delete signals. It seems that the session object and LogEntry object were being saved as well creating multiple signals despite setting the dispatch_uid.

What worked for me was:

from django.contrib.admin.models import LogEntry
from django.contrib.sessions.models import Session

....

if sender in [LogEntry, Session]:
    return 
else:
    # do your thing here
