extending django user model

I am extending the User object in django and have a user profile. So using the post_save hook I save a user profile in the following way:

class UserProfile(models.Model):
    user = models.OneToOneField(User)

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

post_save.connect(create_user_profile, sender=User)

It works fine when I run the shell, via python manage.py shell; saving a user object and user profile in the tables but if I test by launching a request, in the views.py that handles that request I do the following

def handleRequest(r开发者_如何学运维equest):
    user = User(username="test",email="test",password="test")

    user.save()

Of course I created a HttpResponse and returned a response as well but omitted it for brevity. The results are i get a User entry saved in auth_user but no user profile. What the dealy? Please help.

can not access the user profile, because you have in the user profile is a relationship.

you need add fields.

class UserProfile(models.Model):
    url = models.URLField()
    home_address = models.TextField()
    phone_numer = models.PhoneNumberField()
    user = models.ForeignKey(User, unique=True)
