Create OneToOne instance on model creation

Question

I\'m building my first django app. I have a user, and the user has a list of favourites. A user has exactly one list of favourites, and that list belongs exclusively to that

Answer 1

One way would be to register a post_save signal with next handler:

def user_save(sender, instance, created, **kwargs):
  if created:
     FavouriteList.objects.get_or_create(user=instance)
