I am setting up foreign key constraints in my database and wasn't sure if it was possible to set them up on polymorphic relationships. Any help is greatly appreciated. Thanks.
Hi Ben,

This isn't possible by default. A rather complex workaround is to use stored procedures that fire on insert and update triggers, but I'd advise against it because it's far from the Rails idiom.
