get_or_create and foreign keys

[felix]

this is not the issue previously posted by somebody else.

I think I found a bug with Manager get_or_create and foreign key
fields when specifying with foreigntable__id

class ObjectPermission(models.Model):

    permission = models.CharField(blank=False, max_length=20)

    user = models.ForeignKey(User,blank=True,null=True)

    objects = ObjectPermissionManager()

note that user may be null

class ObjectPermissionManager(models.Manager):

    def set_perm(self,permission,user_id):
        import pdb; pdb.set_trace()

        (perm,created) = self.get_or_create
(permission=permission,user__id=user_id)


(Pdb) user_id
17L

# user_id is incorrect when using get_or_create
(Pdb) self.get_or_create(permission=permission,user_id=user_id)
*** FieldError: Cannot resolve keyword 'user_id' into field. Choices
are: id, permission, user

# using user__id
(Pdb) (op,created) = self.get_or_create
(permission=permission,user__id=user_id)
(Pdb) op
<ObjectPermission: ObjectPermission object>

# but user_id was set to null
(Pdb) op.user_id
(Pdb) op.user

here is the crux of the issue :

# if using create, then user_id is correct
(Pdb) self.create(permission=permission,user_id=user_id)

# if using get, then user__id is correct
(Pdb) self.get(permission=permission,user__id=user_id)
*** DoesNotExist: ObjectPermission matching query does not exist.

If someone else can confirm or deny that its a bug then I'll
investigate further and maybe cure it.

thanks
