实体渲染不起作用

Question

我正在尝试在模板中呈现查询，但出现此错误：

The type hint of parameter "commentoarticle" in method
"addCommentoArticle" in class "AppBundle\Entity\Article" is invalid.

我不知道我做错了什么。

这是我要渲染的实体：

<?php
namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * CommentoArticle
 * 
 * @ORM\Table()
 * @ORM\HasLifecycleCallbacks
 *  @ORM\Entity
 */
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;

    /**
     * @var string
     *
     * @ORM\Column(name="testo", type="text")
     */
    private $testo;

    /**
     * @var datetime
     *
     * @ORM\Column(name="data", type="datetime")
     */
    public $data;

    /**
     *@ORM\ManyToOne(targetEntity="Article",inversedBy="commentoarticle")
     * @ORM\JoinColumn(name="article_id",referencedColumnName="id")
     */
    protected $article;

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set nome
     *
     * @param string $nome
     *
     * @return Commento
     */
    public function setNome($nome)
    {
        $this->nome = $nome;

        return $this;
    }

    /**
     * Get nome
     *
     * @return string
     */
    public function getNome()
    {
        return $this->nome;
    }

    /**

     *
     * @param string $testo
     *
     * @return Commento
     */
    public function setTesto($testo)
    {
        $this->testo = $testo;

        return $this;
    }

    /**
     * Get testo
     *
     * @return string
     */
    public function getTesto()
    {
        return $this->testo;
    }


    /**
     * Set data
     *
     * @param \DateTime $data
     *
     * @return Commento
     */
    public function setData($data)
    {
        $this->data = $data;

        return $this;
    }

    /**
     * Get data
     *
     * @return \DateTime
     */
    public function getData()
    {
        return $this->data;
    }

    /**
     * Set article
     * 
     * @param \AppBundle\Entity\Article $article
     * @return CommentoArticle
     */
    public function setArticle(\AppBundle\Entity\Article $article=null)
    {
        $this->article = $article;

        return $this;
    }

    /**
     * Get article
     *
     * @return \AppBundle\Entity\Article 
     */
    public function getArticle()
    {
        return $this->article;
    }

}

     */
    public function getCommentoArticle()
    {
        return $this->commentoarticle;
    }
}

在控制器中，我可以执行以下操作：

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？

Answer 1

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 \\AppBundle\\Entity\\Commento或\\AppBundle\\Entity\\Commento吗？
