构建 Symfony 4.1 应用程序。在我的 ProfileController ...
我有一个带有表单的 booking_new 方法来创建一个新的预订:
/**
* @Route("/profile/booking/new", name="profile_booking_new")
*/
public function booking_new(EntityManagerInterface $em, Request $request)
{
$form = $this->createForm(BookingFormType::class);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
/** @var @var Booking $booking */
$booking = $form->getData();
$booking->setUser($this->getUser());
$em->persist($booking);
$em->flush();
return $this->redirectToRoute('profile_booking_show');
}
return $this->render('profile/bookings/booking_new.html.twig',[
'bookingForm' => $form->createView()
]);
}

然后我有一个 booking_show 方法来渲染单个预订页面,并将路由设置为预订 ID:
/**
* @Route("/profile/booking/{id}", name="profile_booking_show")
*/
public function booking_show(BookingRepository $bookingRepo, $id)
{
/** @var Booking $booking */
$booking = $bookingRepo->findOneBy(['id' => $id]);
if (!$booking) {
throw $this->createNotFoundException(sprintf('There is no booking for id "%s"', $id));
}
return $this->render('profile/bookings/booking_show.html.twig', [
'booking' => $booking,
]);
}

创建预订后,我想将用户重定向到具有正确 ID 的显示预订视图。
运行服务器并收到此错误...
ERROR: Some mandatory parameters are missing ("id") to generate a URL for route "profile_booking_show".

我理解错误,但我该如何解决?如何设置刚刚创建的预订的 id 而不需要查询 id?
一旦新实体被持久化和刷新,你可以像这样使用它:
$em->persist($booking);
$em->flush();
return $this->redirectToRoute('profile_booking_show', ['id' => $bookig->getId()]);
