无效的 Doctrine2 映射：实体-class 'Downloads' 映射无效

Question

我正在尝试定义一个 OneToMany 双向（以避免 ManyToMany 和额外的 table）并且我正在做（我认为）正如文档所说 here但肯定我遗漏了一些东西，因为我在运行 doctrine:schema:validate 命令后收到此错误：

The association PlatformBundle\Entity\Downloads#identifier refers to the owning side field PlatformBundle\Entity\Identifier#downloads which does not exist.

这是实体的样子（只是相关字段）：

class Identifier
{
    /*
     * @var Downloads
     * @ORM\ManyToOne(targetEntity="Downloads", inversedBy="identifier")
     * @ORM\JoinColumn(name="downloads_id", referencedColumnName="id")
     */
    protected $downloads;
}

class Downloads
{
    /**
     * @var Collection
     * @ORM\OneToMany(targetEntity="Identifier", mappedBy="downloads")
     */
    protected $identifier;

    public function __construct() {
        $this->identifier = new ArrayCollection();
    }
}

这是一个下载分配给多个标识符的关联。我在这里做错了什么或遗漏了什么？

Answer 1

您在 Identifier Class 中缺少一个 * :

/**<- this one could cost you many hours :P
 * @var Downloads
 * @ORM\ManyToOne(targetEntity="Downloads", inversedBy="identifier")
 * @ORM\JoinColumn(name="downloads_id", referencedColumnName="id")
 */
protected $downloads;
