#10157 closed (fixed)

Assignment to a reverse OneToOne overwrites related object's PK

Description

example models:

class User(models.Model):
    name = models.CharField(max_length=10)
    def __unicode__(self):
        return '<USER: %s>' % self.name
        
class UserProfile(models.Model):
    user = models.OneToOneField(User, related_name='profile', null=True)


When I try to assign a UserProfile instance to a User instance's “profile” attribute, UserProfile's PK AutoField gets overwritten with the User instance:

>>> u = User(name='test')
>>> p = UserProfile()
>>> print p.id, p.user
None None
>>> u.profile = p
>>> print p.id, p.user
<USER test> <USER test>
# Expected: None <USER test>
