16173	manager.get on foreign key fields (related fields)	nitinbhide@…	nobody	"__get__ on ForeignKey field uses manager to query the values.

The code is as given below

# If the related manager indicates that it should be used for
            # related fields, respect that.
            rel_mgr = self.field.rel.to._default_manager
            db = router.db_for_read(self.field.rel.to, instance=instance)            
            if getattr(rel_mgr, 'use_for_related_fields', False):
                rel_obj = rel_mgr.using(db).get(**params)
                
Check the last line 'rel_obj = rel_mgr.using(db).get(**params)' for using rel_mgr with multiple databases. rel_mgr.using(db) returns a queryset. If developer has written a Custom Manager class for which 'get' is overriden, then Custom Managers 'get' function will never get called. This results in surprises to the developer. I think this line should changed to 

    rel_obj = rel_mgr.db_manager(db).get(**params)
