The twinnable_has_many relation is the equivalent of the FuelPHP native has_many relation (moreover, it extends has_many). The difference is that the link is not made on the primary key but on the context common ID.
If you use the twinnable_has_many relation, the model must implement Twinnable behaviour.
Changed in version 4.2: Before the 4.2 (Dubrovka) version, the linked model also need to implement Twinnable behaviour.
