异常"缺少一些强制参数"[symfony2]

我希望user能够在其公共配置文件中留下关于user的评论(评论)。

一旦我刷新公共配置文件页面，我有这个错误:

在呈现模板期间抛出异常("控制器"飞行控制器' BookingsBundle ' '为PostController: commentAction ()要求您为"$entity"参数提供一个值(因为没有默认值或因为有一个非可选参数在这个之后)ApplicationSonataUserBundle:简介:UserShow.html。修改第108行

公共配置文件的url如下所示:

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

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>

添加:

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()));
}
