例外「一些強制性參數丟失」[symfony2]

Question

我想user能夠對其公開的個人資料上的user留下評論（評論）。

一旦我刷新公開資料頁上我有這樣的錯誤：

An exception has been thrown during the rendering of a template ("Controller "FLY\BookingsBundle\Controller\PostController::commentAction()" requires that you provide a value for the "$entity" argument (because there is no default value or because there is a non optional argument after this one).") in ApplicationSonataUserBundle:Profile:UserShow.html.twig at line 108.

公用配置文件看起來像這樣的網址：

http://127.0.0.1/symfony/web/app_dev.php/user/show/john/26 

的routing.yml

userShow: 
    pattern: /user/show/{entity}/{slug} 
    defaults: { _controller: FLYBookingsBundle:Post:userShow } 


comment: 
    pattern: /user/show/{entity}/{slug} 
    defaults: { _controller: FLYBookingsBundle:Post:comment } 
    requirements: 
     _method: POST 

PostController.php

public function userShowAction($entity) 
{ 

    $em = $this->getDoctrine()->getManager(); 
    $entity = $em->getRepository('ApplicationSonataUserBundle:User')->findBy(array('username' => $entity)); 

    $user = $em->getRepository('ApplicationSonataUserBundle:Avatar')->findBy(array('user' => $entity)); 

    return $this->render('ApplicationSonataUserBundle:Profile:UserShow.html.twig', array('user' => $user,'entity' => $entity)); 
} 

。

public function commentAction(Request $request,$entity) 
{ 
    $em = $this->getDoctrine()->getManager(); 
    $user = $this->container->get('security.token_storage')->getToken()->getUser(); 
    $comment = new Comment(); 
    $entity = $em->getRepository('ApplicationSonataUserBundle:User')->findBy(array('username' => $entity)); 
    $form = $this->createForm(new CommentType(),$comment); 
    dump($form); 
    if ($this->get('request')->getMethod() == 'POST') { 
     $form->handleRequest($request); 
     if ($form->isSubmitted() && $form->isValid()) { 
      $comment->setCreatedAt(new \DateTime()); 
      $comment->setApproved(true); 

      $comment->setRecipient(); 

      $comment->setAuthor($this->container->get('security.token_storage')->getToken()->getUser()); 
      $em->persist($comment); 
      $em->flush(); 
      $this->get('session')->getFlashBag()->add(
       'success', 
       'Your comment was succesfully added' 
      ); 
     } 
     return $this->redirect($this->generateUrl('userShow', array(
      'entity' => $entity, 
      //'slug' => $slug, 
     ))); 

    } 

    return $this->render('ApplicationSonataUserBundle:Profile:commentForm.html.twig', array('entity' => $entity,'user' => $user,'comment' => $comment, 
     'form' => $form->createView())); 
} 

UserShow.html.twig

{% for entity in entity %} 

    <div class="row">      
     <div class="col-sm-9"> 

    {{ render(controller('FLYBookingsBundle:Post:comment')) }} 

      </div> 
     </div> 
{% endfor %} 

CommentForm.html.twig

  <form action="{{ path('comment', {'entity': entity, 'slug':entity.user.id}) }}" method="POST"> 
     {{ form_start(form) }} 
     {{ form_errors(form) }} 
        <div class="form-group"> 
         <label>Review Text</label> 
         {{ form_widget(form.body, { 'attr': {'class': 'form-control','style': 'width: 100%', } }) }} 
         {{ form_errors(form.body) }} 
        </div> 
       <button style="float: right;font-size: 14px; height: 40px; width: 180px;" type="submit">Leave a Review</button> 
     {{ form_rest(form) }} 
    </form> 

ADD：

public function userShowAction(Request $request,$entity,$slug) 
{ 

    $em = $this->getDoctrine()->getManager(); 
    $entity = $em->getRepository('ApplicationSonataUserBundle:User')->findBy(array('username' => $entity)); 
    $useravatar = $em->getRepository('ApplicationSonataUserBundle:Avatar')->findBy(array('user' => $entity)); 
    $recipient = $em->getRepository('ApplicationSonataUserBundle:User')->findOneBy(array('id' => $slug)); 
    $comment = new Comment(); 
    $user = new User(); 
    $form = $this->createForm(new CommentType(),$comment); 
    if ($this->get('request')->getMethod() == 'POST') { 
     $form->handleRequest($request); 
     if ($form->isSubmitted() && $form->isValid()) { 
      $comment->setCreatedAt(new \DateTime()); 
      $comment->setApproved(true); 
      $comment->setRecipient($recipient); 
      dump($entity); 
      $comment->setAuthor($this->container->get('security.token_storage')->getToken()->getUser()); 
      $em->persist($comment); 
      $em->flush(); 
      $this->get('session')->getFlashBag()->add(
       'success', 
       'Your comment was succesfully added' 
      ); 
     } 

     return $this->redirect($this->generateUrl('userShow', array(
      'entity' => $comment->getRecipient(), 
      'slug' => $slug 
     ))); 


    } 

    return $this->render('ApplicationSonataUserBundle:Profile:UserShow.html.twig', array('useravatar' => $useravatar,'user' => $user,'entity' => $entity,'form' => $form->createView())); 
}

user.php的

/**

*/ 
protected $commentrecipient; 

Answer 1

FLYBookingsBundle:Post:comment需要的參數。

變化{{ render(controller('FLYBookingsBundle:Post:comment')) }}到

{{ render(controller('FLYBookingsBundle:Post:comment', {'entity' : entity)) }} 

在UserShow.html.twig
