ForeignKey field and Multiple database bug

[vital.fadeev@…]

Hello.

Problem:

I get error "Incorrect table name" when I save entry.

Details:

I have two models:

# db1
class User(models.Model):
  id = models.PositiveIntegerField(primary_key=True)

# db2
class Realtor(models.Model):
  realtor_id = ForeignKey(User)

where 'User' in using 'db1' and 'Realtor' using 'db2' (via router).
I get error while save.
When trace I see variables who using db2.
And SQL-requests going to db2.

I.e. SQL-requests runned on Realtor's database - 'db2'
(in db2 no table 'User' and I get 'Incorrect table name' error)[[BR]

Solution:

(Please, say me right I or no)
ForeignKey field in validate() function using database from field instance class.
But need using from related class.

using = router.db_for_read(model_instance.__class__, instance=model_instance)

(please, see attachment - patch)

I see it in 1.2, 1.3, 1.4rc1.

By design, Django doesn't support foreign keys across databases. See ​the docs for more information on this design decision.

In version 1.6.5 this bug still exists, this solution was distributed?

I Created a gist around this ticket that subclasses ForeignKey. No need for a code change to django: ​https://gist.github.com/gcko/de1383080e9f8fb7d208
