Comment:
Another example with same problem when OneToOneField related to the
inherited model.
{{{#!python
from django.contrib.auth.models import User
(...)
class PersonUser(User):
name = models.CharField(max_length=255)
surname = models.CharField(max_length=255)
class OnetoOneToUser(Model):
user = models.OneToOneField(Parent, blank=True, null=True)
info = models.CharField(max_length=255, default='some parent info')
}}}
{{{#!python
>>> person_user = PersonUser(username = 'first_user', name='1',
surname='1')
>>> person_user.save()
>>> User.objects.all()
[<User: first_user>]
>>> one_to_one = OnetoOneToUser(user=person_user)
>>> one_to_one.save()
>>> person_user_2 = PersonUser(username = 'second_user', name='1',
surname='1')
>>> person_user.save()
>>> User.objects.all()
[<User: second_user>]
}}}
