3188	OneToOne field - ChangeManipulator looks for related primary key	alex@…	nobody	"I am posting it as bug, I have already tried to post to django-developers, no feedback has been received.

Assume I relate django.contrib.auth.User to Customer using OneToOne relation. If I do this,
I am unable to edit this user via /admin since ChangeManipulator brings up this error:

{{{
Exception Type:         KeyError
Exception Value:        'user'
Exception Location:
        /usr/lib64/python2.4/site-packages/django/db/models/manipulators.py in
save, line 163
}}}

Obviously, this is because Manipulator tries to use related field ID as
for ForeignKey, but it
seems to be wrong approach, since with OneToOne field we should
directly search on User.

I have tried to change the code to something like this:

And it works fine for me. I am submitting this as working patch,
but I consider it to be a temp. solution only.
