Już zarejestrowany w/appname /: Model użytkownika jest już zarejestrowany

Question

Próbuję połączyć użytkownika django.contrib.auth z moim własnym UserProfile i otrzymuję błąd "AlreadyRegistered", gdy wejdę na stronę .

Oto traceback:

Exception Type: AlreadyRegistered at /appname/ 
Exception Value: The model User is already registered 

Jestem całkiem pewien, że to wynika z mojej aplikacji models.py, skoro to wszystko, co zmieniło się w sposób istotny, wierzę.

from django.db import models 
from django.contrib.auth.models import User 
from django.db.models.signals import post_save 

class Tag(models.Model): 
     pics = models.ManyToManyField('Picture', blank=True) 
     name = models.CharField(max_length=30) 

     def __unicode__(self): 
       return self.name 

class UserProfile(models.Model): 
     name = models.CharField(max_length=20) 
     date_joined = models.DateTimeField('date joined') 
     auth_user = models.OneToOneField(User) 

     def __unicode__(self): 
       return self.name 

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

post_save.connect(create_user_profile, sender=User) 

class Picture(models.Model): 
     name = models.CharField(max_length=100) 
     pub_date = models.DateTimeField('date published') 
     tags = models.ManyToManyField('Tag', blank=True) 
     owner = models.ForeignKey('UserProfile') 
     content = models.ImageField(upload_to='instaton') 

     def __unicode__(self): 
       return self.name 

class Comment(models.Model): 
     content = models.CharField(max_length=500) 
     date = models.DateTimeField('date commented') 
     commenter = models.ForeignKey('UserProfile') 
     pic = models.ForeignKey('Picture') 

     def __unicode__(self): 
       return self.content

Podczas definiowania niestandardowego admina użytkownika w swojej aplikacji admin.py, należy najpierw wyrejestrować domyślny User modelu administratora przed zarejestrowaniem własną rękę.

admin.site.unregister(User) 
admin.site.register(User, MyUserAdmin)
