Symfony 2 で記事にコメントを追加しようとしていますが、POST を実行すると白いページが表示されます。
コントローラーは次のとおりです。
public function articleAction($id)
{
$repository = $this->getDoctrine()
->getManager()
->getRepository('PortfolioPortfolioBundle:Article');
$article = $repository->find($id);
if($article === null)
{
throw $this->createNotFoundException('Article[id='.$id.'] inexistant.');
}
$comment = new Comment();
$form = $this->createFormBuilder($comment)
->add('autor', 'text')
->add('content', 'textarea')
->getForm();
$request = $this->get('request');
if ($request->getMethod() == 'POST') {
$form->bind($request);
if ($form->isValid()) {
$article->addComment($comment);
$em = $this->getDoctrine()->getManager();
$em->persist($article);
$em->persist($comment);
$em->flush();
}
}
return $this->render('PortfolioPortfolioBundle:Portfolio:article.html.twig', array(
'article' => $article, "active" => "article", 'form' => $form->createView()
));
}
記事のモデルは次のとおりです。
public function addComment(\Portfolio\PortfolioBundle\Entity\Comment $comment)
{
$this->comments[] = $comment;
$comments->setArticle($this);
return $this;
}
public function removeComment(\Portfolio\PortfolioBundle\Entity\Comment $comment)
{
$this->comments->removeElement($comment);
}
public function getcomments()
{
return $this->comments;
}
コメントモデルは次のとおりです。
<?php
namespace Portfolio\PortfolioBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Comment
*
* @ORM\Table()
* @ORM\Entity(repositoryClass="Portfolio\PortfolioBundle\Entity\CommentRepository")

}

{

}

*/
public function getAutor()
{
return $this->autor;
}
/**

* @return Comment
*/
public function setDate($date)
{
$this->date = new \DateTime("now");
return $this;
}
/**

*
* @return \DateTime
*/
public function getDate()
{
return $this->date;
}
/**

*/
public function setContent($content)
{

return $this;
}
/**

public function getContent()
{
return $this->content;
}

{
$this->article = $article;
return $this;
}
/**
* Get article
*
* @return \Portfolio\PortfolioBundle\Entity\Article
*/
public function getArticle()
{
return $this->article;
}
}
ビューは次のとおりです。
<form class="comment-text" method="post" {{ form_enctype(form) }}>
<div class="controls-group col-md-10">
<div class="controls">
<!--<textarea id="content" name="content" class="form-control" placeholder="Add a comment" rows="5"></textarea><br/>-->
{{ form_widget(form) }}
<button id="contact-submit" type="submit" class="btn btn-primary">Send</button>
