This is a foreign key constraint issue that I still haven't come up with a good solution for. Similar to issue #8. Ideally, I would like to add some logic to sort the models based on dependencies so that we never run into this issue. If you have some ideas on how to accomplish this, I'd love some help :)

In the meantime, I'd recommend seeding with the code version (ie: seeder.add_entity(Model, 10) in an order based on their dependencies to avoid this conflict
