post_save signal not working in Django 1.7

[Zach LeRoy]

I have a block of code that works fine in Django 1.6.10 but does not work at all in Django 1.7.3.  I would expect my log statement to print every time a Django User is created and this is the behavior in 1.6.10:

import logging

from django.contrib.auth.models import User

from django.db import models

from django.db.models.signals import post_save

from django.dispatch import receiver

log = logging.getLogger(__name__)

class UserProfile(models.Model):

    uuid = models.CharField(max_length=36)

    user = models.OneToOneField(User)

@receiver(post_save, sender=User)

def create_user_profile(sender, instance, created, **kwargs):

    """

    When a new user is created, add a UserProfile

    """

    log.debug('received post save signal: {}'.format(instance))

    if created:

        UserProfile.objects.create(user=instance)

Hi,

Are you using AUTH_USER_MODEL?

I assume your logging is set up correctly?

Here's a snippet from one of my projects if you want to try out some similar code:

def user_save_handler(sender, **kwargs):
    user = kwargs['instance']
    try:
        user.userprofile
    except UserProfile.DoesNotExist:
        user_profile = UserProfile(user=user)
        user_profile.__dict__.update(user.__dict__)
        user_profile.save()
post_save.connect(user_save_handler, sender=User)

Something similar is happening with me too: on a post_save of model it isn't created yet on database, so several 

error are raised by functions which expect that it is already on DB.

When the post_save handler ends, the object is saved normally.

Hi,

Does the object in post_save have a pk/id?

Are you using transactions?
