Question

when i try to create superuser from shell or via manage.py or from Django-Admin page ; it throws error like :

IntegrityError at /admin/auth/user/add/
null value in column "link_karma" violates not-null constraint

Here is my models.py [User Part]:

class User_Profile(models.Model):

    user = models.OneToOneField(User)
    link_karma = models.IntegerField()
    comment_karma = models.IntegerField()
    avatar = models.CharField(max_length=100)

    def create_user_profile(sender,instance,created,**kwargs):
        if created:
            User_Profile.objects.create(user=instance)
    post_save.connect(create_user_profile, sender=User)

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

i added fallowing line in to settings.py:

AUTH_PROFILE_MODULE = 'accounts.User_Profile'

before add this line ; it was the same.

Note : i tried to change type of link_karma field to CharField. it is same.

Note : If any additional data needed ; i can add it.

Try setting blank=True, null=True for both link_karma and comment_karma. You’re not passing any values to those fields so when your create statement tries to create the object, it doesn’t know what to give link_karm hence the error.

As goliney correctly pointed out, you dont need email in your User_Profile model as User already has it.
