無法猜測如何獲得主義

Symfony的3
CalendarEntity可以是ChocolateEntity
BoxEntity父父WrapperEntity
WrapperEntity可以是ChocolateEntity父母永遠是小孩的BoxEntity
ChocolateEntity只能是任CalendarEntity或WrapperEntity

[問題]

當我嘗試從任一CalendarEntity或BoxEntity導航到chocolate/show或chocolate/edit路線，我得到這個孩子消息：

無法猜測如何從請求信息

chocolate/index和chocolate/new路線做工精細獲得學說實例。
直到我來添加代碼在控制器爲CalendarEntity，每個路線工作正常。

檢查dev.log文件給了我這個：

// Route: /calendar/{idCalendar}/chocolate/{idChocolate}/show 
request.INFO: Matched route "calendar_chocolate_show". {"route":"calendar_chocolate_show","route_parameters":{"_controller":"AppBundle\\Controller\\ChocolateController::showAction","idCalendar":"1","idChocolate":"3","_route":"calendar_chocolate_show"},"request_uri":"http://sphere.gdn/app_dev.php/calendar/1/chocolate/3/show","method":"GET"} [] 

// Route: /box/{idBox}/wrapper/{idWrapper}/chocolate/{idChocolate}/show 
request.INFO: Matched route "wrapper_chocolate_show". {"route":"wrapper_chocolate_show","route_parameters":{"_controller":"AppBundle\\Controller\\ChocolateController::showAction","idBox":"1","idWrapper":"1","idChocolate":"1","_route":"wrapper_chocolate_show"},"request_uri":"http://sphere.gdn/app_dev.php/box/1/wrapper/1/chocolate/1/show","method":"GET"} []

在我看來，Symfony的對每個請求都需要paramters，並沒有多餘的參數。
我不能指出如何解決這個問題。

你用過@ParamConverter嗎？ – Vamsi

由於POB實體hawliau ICHI唐娜angen在editAction()額外的參數傳遞給您的showAction()。

收回你的代碼，showAction()會變成這樣：

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

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

和你editAction()會變成這樣：

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(), 
     )); 
    }

每一個信息都在ChocolateEntity，你只需要得到家長的每個時間，然後是所需的參數。

像你一樣的東西，只有showAction()和newAction()需要有參數，這是因爲，在這兩種情況下，你不返回一個特定ChocolateEntity

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

而像editAction()你可以得到父母沒有通過他們。

另外請注意，你的樹枝會改變一點。由於爲例，當你顯示一個實體（showAction()），鏈接「回到列表」將改變基礎的路線，它就會放棄這樣的事情：

{% 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 %}

這樣做，會提示Symfony的到即使您僅通過ChocolateEntity作爲參數，也可以獲取父母的數據。其他的樹枝文件也是一樣的。

希望它能幫助你。

這個話題很好吃，我自己會得到一些巧克力。

確實解決了我的問題！將它應用到我的項目上，而我在它的時候，感謝詳細回覆！ – Preciel

所以Preciel，在ChocolateController嘗試：

/** 
* 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) { 
...

要feddwl @Vamsi下是正確的。
