How to use:

  1. puts this code at the end of the models.py file who haves the User Profile class declared;
  2. verify if your User Profile class has the name 'UserProfile'. If not, change the code to the right name.

About: this snippet makes the ORM create a profile each time an user is created (or updated, if the user profile lost), including 'admin' user.

This is no longer valid as the way dispatcher works has been updated.

Any shot at an update?

For Django 1.0:

def user_post_save(sender, instance, **kwargs):
    profile, new = UserProfile.objects.get_or_create(user=instance)

models.signals.post_save.connect(user_post_save, sender=User)

For Django 1.3, using the new @receiver decorator:

from django.db.models.signals import post_save
from django.dispatch import receiver

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    """Create a matching profile whenever a user object is created."""
    if created: 
        profile, new = UserProfile.objects.get_or_create(user=instance)

Hello, was playing around with signals and came across an issue. Was able to use the receiver decorator approach from Ori when using the built in signals (i.e. post_save, etc.) put when I tried to use that approach with a custom signal it does not work.

I confirmed that the custom signal works if I use the approach

custom_signal.connect(custom_receiver)

and all works. but

@receiver(custom_receiver, sender=MyModel) def signal_receiver(sender, **kwargs) print 'in signal_receiver'

This does not work, does the decorator approach not work with custom signals?

Thanks
