Description
class A(models.Model): ... class B(models.Model): a = models.ForeignKey(A) ...
Database router set DIFFERENT databases for reading for this classes and allowing relations.
B.objects.all() result:
SELECT ... FROM A_table LEFT OUTER JOIN B_table ON ... ORDER BY ... ASC';
So it trying to read both related objects from one database ignoring router.

Working as designed. Django doesn't support running a single query across two different databases; this is documented behavior.
