Django - Create user profile on user creation

Question

I'm following Django documentation here in order to achieve a simple objective: Create a user profile as soon as a new user is created.

I have an 'accounts' app and my accounts.models looks like this:

# -*- coding: utf-8 -*- from django.db import models from django.db.models.signals import post_save from django.contrib.auth.models import User from main.models import Store  class UserProfile(models.Model):      GENRE_CHOICES = (         ('m', 'Masculino'),         ('f', 'Feminino'),     )     MARITAL_STATUS_CHOICES = (         ('s', 'Solteiro'),         ('c', 'Casado'),         ('d', 'Divorciado'),         ('v', 'Viúvo'),     )      user = models.ForeignKey(User, unique=True)     birth_date = models.DateField()     genre = models.CharField(max_length=1, choices=GENRE_CHOICES)     address = models.CharField(max_length=150)     postal_code_4 = models.PositiveIntegerField()     postal_code_3 = models.PositiveIntegerField()     locatity = models.CharField(max_length=30)     marital_status = models.CharField(max_length=1, choices=MARITAL_STATUS_CHOICES)     child_amount = models.PositiveSmallIntegerField()     is_merchant = models.BooleanField(default=False)     store = models.ForeignKey(Store, null=True)  def create_user_profile(sender, instance, created, **kwargs):     if created:         UserProfile.objects.create(user=instance)  post_save.connect(create_user_profile, sender=User) 

Everything looks fine to me but when trying to add a new user (using django admin), instead of having a newly created user and user profile, I get the following error: InternalError at /admin/auth/user/add/ current transaction is aborted, commands ignored until end of transaction block

Here is the traceback error part:

/djangoProjects/lwboanova/lwboanova/apps/accounts/models.py in create_user_profile  34: UserProfile.objects.create(user=instance) 

It seems like an integrity error but I'm not getting the reason for it.

Would be great if any of ya could give me some help on this.

You shouldn't use:

user = models.ForeignKey(User, unique=True) 

Instead use this:

from django.conf import settings .. user = models.OneToOneField(settings.AUTH_USER_MODEL)
