我试图在模板中呈现查询，但是我收到此错误：
The type hint of parameter "commentoarticle" in method
"addCommentoArticle" in class "AppBundle\Entity\Article" is invalid.
我不知道自己做错了什么。
这是我的实体，我想呈现：
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* CommentoArticle
*
* @ORM\Table()
* @ORM\HasLifecycleCallbacks

*/
class CommentoArticle
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="nome", type="string", length=255)
*/
private $nome;
/**

private $testo;

public $data;

*/
protected $article;
/**

public function getId()
{
return $this->id;
}

public function setNome($nome)
{
$this->nome = $nome;
return $this;
}

{
return $this->nome;
}

{
$this->testo = $testo;
return $this;
}

{
return $this->testo;
}

在控制器中我有我的动作：
public function commentiarticoliAction()/* ROTTA "commentiarticoli" */
{
$em = $this->getDoctrine()->getManager();
$query = $em->createQuery(
'SELECT ca
FROM AppBundle:CommentoArticle ca'
);
$repository = $query->getResult();
return $this->render('administration/commentiarticoli.html.twig', array(
'results' => $repository
));
}
错误在哪里？
答案 0 :(得分：2)
这是有问题的部分：
/**
* Add commentoarticle
*
* @param \AppBundle\Entity\CommentoArticle $commentoarticle
*
* @return Article
*/
public function addCommentoArticle(\AppBundle\Entity\Commento $commentoarticle)
{
$this->commentoarticle[] = $commentoarticle;
return $this;
}
您要添加\AppBundle\Entity\CommentoArticle还是\AppBundle\Entity\Commento？
