    @resolve_only_args
    def resolve_ships(self):
        return get_ships()

    @resolve_only_args
    def resolve_rebels(self):
        return get_rebels()

    @resolve_only_args
    def resolve_empire(self):
        return get_empire()


class Mutation(graphene.ObjectType):
    introduce_ship = IntroduceShip.Field()


# We register the Character Model because if not would be
# inaccessible for the schema
schema = Schema(query=Query, mutation=Mutation, types=[Ship, Character])
