php - 未定义索引 "order"，映射错误？

Question

我有一个 ManyToMany 关系定义如下:

OrderHasMedia.php

/**
 * @ORM\Entity
 * @ORM\Table(name="order_has_media__media")
 */
class OrderHasMedia {

    /**
     * @ORM\Id
     * @ORM\ManyToOne(targetEntity="PL\OrderBundle\Entity\Order", inversedBy="order_document", cascade={"all"})
     */
    protected $order;

    /**
     * @ORM\Id
     * @ORM\ManyToOne(targetEntity="Application\Sonata\MediaBundle\Entity\Media", inversedBy="order_document", cascade={"all"})
     */
    protected $media;

}

Order.php

/**
 * @ORM\Entity
 * @ORM\Table(name="tb_order")
 * @Gedmo\Loggable
 */
class Order {

    /**
     * @ORM\OneToMany(targetEntity="PL\OrderBundle\Entity\OrderHasMedia", mappedBy="order" , cascade={"all"})
     */
    protected $order_document;

}

Media.php

class Media extends BaseMedia {

    /**
     * @var Collection
     * @ORM\OneToMany(targetEntity="PL\OrderBundle\Entity\OrderHasMedia", mappedBy="media", cascade={"all"})
     *
     */
    protected $order_document;

}

如果我尝试添加新订单，我会收到此错误:

ContextErrorException: Notice: Undefined index: id in /var/www/html/apps/portal_de_logistica/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/BasicEntityPersister.php line 685

错在哪里？我的映射有什么问题？

Answer 1

经过几个小时的头痛，我终于找到了我的错误所在，我想分享一下，以防其他人遇到同样的问题。解决方案是将 @ORM\JoinColumn() 添加到注释中，所以我现在的代码，仅针对 OrderHasMedia 实体如下:

/**
 * @var Order
 * @ORM\Id
 * @ORM\ManyToOne(targetEntity="PL\OrderBundle\Entity\Order", inversedBy="order_document", cascade={"all"})
 * @ORM\JoinColumn(name="order_no_order", referencedColumnName="no_order")
 */
protected $order;

/**
 * @var Media
 * @ORM\Id
 * @ORM\ManyToOne(targetEntity="Application\Sonata\MediaBundle\Entity\Media", inversedBy="order_document", cascade={"all"})
 * @ORM\JoinColumn(name="media__media_id", referencedColumnName="id")
 */
protected $media;

这就解决了问题。希望这会帮助其他人
