十、`action`：作业柜台，所有写操作都从这里过

export async function action({ request }: ActionFunctionArgs) {
  const formData = await request.formData();
  const name = formData.get("name");
  const type = formData.get("type");

  if (!name) {
    return json(
      { errors: { name: "船名不能为空" } },
      { status: 400 }
    );
  }

  const ship = await createShip({
    name: String(name),
    type: String(type),
  });

  return redirect(`/ships/${ship.id}`);
}
