7240	OneToOneField does not work with profiles in admin (oldforms)	David Sauve <dnsauve@…>	nobody	"When defining a user field as a OneToOneField (instead of the recommended ForeignKey(unique=True)) in a Profile object, the object fails validation when editing in the admin interface.

Here's an example model:

{{{
class Profile(models.Model):
    """"""
    Extra user profile information.
    """"""
    user = models.OneToOneField(User, verbose_name=_('user'))
    icon = models.ImageField(_('icon'), upload_to='profiles', null=True, blank=True)
    address = models.CharField(_('address'), max_length=200, blank=True)
    city = models.CharField(_('city'), max_length=50, blank=True)
    state_province = models.CharField(_('state/province'), max_length=50, blank=True)
    postal_code = models.CharField(_('postal code/zip code'), max_length=10, blank=True)
    country = models.CharField(_('country'), max_length=50, blank=True)
    
    class Meta:
        verbose_name = _('profile')
        verbose_name_plural = _('profiles')
    
    class Admin:
        pass
    
    def __unicode__(self):
        return ""%s, %s"" % (self.user.last_name, self.user.first_name)

    @permalink
    def get_absolute_url(self):
        return ('profiles-details', (), { 'username': self.user.username })
}}}
When using this model, I can create new users and profiles in the admin interface without any issues, however, when trying to edit a instance of a profile, it fails validation with the error: ""This field is required."" and the ""User"" field highlighted.

There is no problem when using the same model, above, to create/edit instances of the profile in the shell:
{{{
>>>u = User.objects.get(username='David')
>>>p = u.get_profile()
>>>p.address = '123 Main St.'
>>>p.save()
}}}
