Found My mistake, create parent_link:
class Employee(User):
user = models.OneToOneField(User, parent_link=True)
address = models.CharField(max_length=50, null=True, blank=True)
phone1 = models.CharField(max_length=15, null=True, blank=True)
phone2 = models.CharField(max_length=15, null=True, blank=True)
skype = models.CharField(max_length=32, null=True, blank=True)
website = models.URLField(null=True, blank=True)
comments = models.TextField(null=True, blank=True)
Here is my signal:
def user_post_save(sender, instance, **kwargs):
Employee.objects.get_or_create(user=instance)
models.signals.post_save.connect(user_post_save, sender=User)
Now i get
IntegrityError at /admin/auth/user/add/
column username is not unique
