Question

我正在为我的工作培训做一个项目。但我面临一个错误，而且无法解决。

所以，我使用关系ManyToOne来加入两件事，即产品类别。

但是当我想添加产品时，我有这个错误：

ContextErrorException：Catchable Fatal Error：类Sam \ VitrineBundle \ Entity \ Categorie的对象无法在D：\ DOCUMENTS \ Dropbox \ COURS \ S4 \ STAGE \ Symfony \ src \ Sam \ VitrineBundle \ Entity \ Produit中转换为字符串.php第124行

我的控制器，我遇到错误的代码。

...
$catRepo = $this->getDoctrine()->getManager()->getRepository('SamVitrineBundle:Categorie');
$cat = $catRepo->findOneById($form["categorie"]->getData());
$product -> setCategorie($cat);
...

我的实体，产品

...
    /**
     * @ORM\ManyToOne(targetEntity="Categorie", inversedBy="produits", cascade={"remove"})
     * @ORM\JoinColumn(name="categorie_id", referencedColumnName="id")
     */
    protected $categorie;

    /**
     * Set categorie
     *
     * @param Sam\VitrineBundle\Entity\Categorie $categorie
     */
    public function setCategorie(\Sam\VitrineBundle\Entity\Categorie $categorie)
    {
      $this->$categorie = $categorie;
    }

    /**
     * Get categorie
     *
     * @return Sam\VitrineBundle\Entity\Categorie 
     */
    public function getCategorie()
    {
      return $this->categorie;
    }
...

对不起，有些变量是法语。类别 - ＆gt;类别产品 - ＆gt;产品

如果有人可以帮助我。问我是否想要更多的信息，但我给你的主要信息我认为错误来自。

Answer 1

在您的实体中

public function setCategorie(\Sam\VitrineBundle\Entity\Categorie $categorie)
{
    $this->categorie = $categorie;
}

而不是

public function setCategorie(\Sam\VitrineBundle\Entity\Categorie $categorie)
{
    $this->$categorie = $categorie;
}
