我正在做一个项目，但我一直看到这个映射问题：

关联 PL\OrderBundle\Entity\Order#company 指的是未定义为关联的反向字段 PL\CompanyBundle\Entity\Company#id。

关联 PL\OrderBundle\Entity\Order#company 指的是不存在的反边字段 PL\CompanyBundle\Entity\Company#id。

关联 PL\OrderBundle\Entity\Order#medias 指的是不存在的拥有方字段 Application\Sonata\MediaBundle\Entity\Media#orders。

除了我阅读和阅读 Doctrine Docs 之外，我不知道如何解决它们，有什么问题？有什么帮助吗？以下是相关实体：

对于初学者，当使用双向 ManyToOnes 和 OneToManys 时，您必须具有 inversedBy 和匹配的 mappedBy。在你的例子中：

/**
 * @ORM\ManyToOne(targetEntity="PL\CompanyBundle\Entity\Company", inversedBy="id")
 */
protected $company;

您拥有的 inversedBy 基本上是在告诉学说，您公司的 id 字段（这是您的主键）是您的订单实体的外键，这是不正确的。你需要有订单：

/**
 * @ORM\ManyToOne(targetEntity="PL\CompanyBundle\Entity\Company", inversedBy="orders")
 */
protected $company;

在公司：

/**
 * @ORM\OneToMany(targetEntity="PL\OrderBundle\Entity\Order", mappedBy="company")
 */
private $orders;

只需遵循文档： http ://docs.doctrine-project.org/en/2.0.x/reference/association-mapping.html
