  • Symfony 3

    • 的父级
  • ChocolateEntity是父BoxEntity
  • WrapperEntity可以是WrapperEntity的父级，并且始终是ChocolateEntity

[问题]

当我尝试从WrapperEntity或chocolate/show导航到chocolate/edit或CalendarEntity路线时，我收到此消息：

  

无法猜测如何从请求信息中获取Doctrine实例

BoxEntity和chocolate/index路由工作正常 直到我在chocolate/new的控制器中添加代码，每条路线都正常工作。

检查dev.log文件给了我这个：

CalendarEntity

在我看来，Symfony对每个请求都需要参数，没有额外的参数 我无法解释如何解决这个问题。

由于每个实体都是相关的，因此您无需将额外参数传递给showAction()或editAction()。

收回您的代码，showAction()将成为：

public function showAction(Chocolate $chocolate) {
    $deleteForm=$this->createDeleteForm($video);

    return $this->render('AppBundle:chocolate:show.html.twig', array(
        'chocolate'=>$chocolate,
        'delete_form'=>$deleteForm->createView(),
    ));
}

你的editAction()会变成这样：

public function editAction(Request $request, Chocolate $chocolate) {
    $deleteForm=$this->createDeleteForm($chocolate);
    $editForm=$this->createForm('AppBundle\Form\ChocolateType', $chocolate);
    $editForm->handleRequest($request);

    if($editForm->isSubmitted() && $editForm->isValid()) {
        $em=$this->getDoctrine()
                 ->getManager();
        $em->persist($chocolate);
        $em->flush();
        if($chocolate->getWrapper() !== null) {
            return $this->redirectToRoute('wrapper_chocolate_edit', 

        array(
            'idBox'=>$chocolate->getWrapper()->getBox()->getIdBox(),
            'idWrapper'=>$chocolate->getWrapper()->getIdWrapper(),
            'idChocolate'=>$chocolate->getIdChocolate()
        ));
    } else {
        return $this->redirectToRoute('calendar_chocolate_edit',
            array(
                'idCalendar'=>$chocolate->getCalendar()->getIdCalendar(),
                'idChocolate'=>$chocolate->getIdChocolate()
                ));
            }
        }

        return $this->render('AppBundle:Dashboard/chocolate:edit.html.twig', array(
            'chocolate'=>$chocolate,
            'edit_form'=>$editForm->createView(),
            'delete_form'=>$deleteForm->createView(),
        ));
    }

每个信息都在ChocolateEntity中，您只需每次都获取父级，然后需要参数。

正如您所做的那样，只有showAction()和newAction()需要有参数，这是因为，在这两种情况下，您都不会返回特定的ChocolateEntity 

public function indexAction(Calendar $calendar=null, Wrapper $wrapper=null)
public function newAction(Request $request, Calendar $calendar=null, Wrapper $wrapper=null)

和editAction()一样，你可以在不通过父母的情况下找到父母。

另请注意，您的树枝会稍微改变一下。 例如，当您显示实体（showAction()）时，“返回列表”链接将根据路线发生变化，然后它将提供如下内容：

{% if chocolate.wrapper is not null %}
    <a href="{{ path('wrapper_chocolate_list', { 'idBox': chocolate.wrapper.box.idBox, 'idWrapper': chocolate.wrapper.idWrapper }) }}">Back to the list</a>
{% else %}
    <a href="{{ path('calendar_chocolate_list', { 'idCalendar': chocolate.calendar.idCalendar }) }}">Back to the list</a>
{% endif %}

这样做，即使您只传递ChocolateEntity作为参数，也会提示Symfony获取父数据。其他树枝文件也是如此。

希望它会对你有所帮助。

所以Preciel，在ChocolateController中尝试：

/**
 * Finds and displays a Chocolate entity.
 *
 * @param Calendar $calendar
 * @param Box $box
 * @param Wrapper $wrapper
 * @param Chocolate $chocolate
 *
 * @return \Symfony\Component\HttpFoundation\Response
 *
 *  @ParamConverter("calendar", class="AppBundle:Calendar")
 *  @ParamConverter("chocolate", class="AppBundle:Chocolate")
 */
public function showAction(Calendar $calendar=null, Box $box=null, Wrapper $wrapper=null, Chocolate $chocolate) {
...

我认为@Vamsi是正确的。
