Question

I wanted to reset my Django project’s database, so I did the following steps:

1. Deleted my SQLite database
2. Did python manage.py syncdb
3. Did python manage.py migrate users --fake

After I create a new account and login, I get the following error message:

no such table: users_userprofile

Here is what my users model.py looks like:

class UserProfile(models.Model):
  user = models.OneToOneField(User)
  joined_goals = models.ManyToManyField(Goal, related_name="joined_goals")
  followingGoals = models.ManyToManyField(Goal, related_name="following_goals")

  def __unicode__(self):
    return self.user.username

  def get_goals(self):
    try:
      goals = Goal.objects.filter(user=self.user)
      return goals
    except Goal.DoesNotExist:
      return []

def create_user_profile(sender, instance, created, **kwargs):
    if created:
      userProfile = UserProfile.objects.create(user=instance)

post_save.connect(create_user_profile, sender=User)

So, there is a UserProfile class, but South did not seem to make the table to hold the user profiles. When I do python manage.py schemamigration users --auto, it says that nothing has seemed to changed. How do I get it to create the userprofiles table?

Answer 1

I had this exact same problem. Turns out that there is a circular dependency of sorts when using South. To get around this problem, don’t create a superuser when you run syncdb, but instead run:

python manage.py createsuperuser

after you have created the database with syncdb. At this point, your profile table will have been created, and the post_save signal will succeed.
