未定义的索引"order"，映射错误？

Question

我有一个ManyToMany关系，定义如下：

OrderHasMedia.php

/**
 * @ORMEntity
 * @ORMTable(name="order_has_media__media")
 */
class OrderHasMedia {
    /**
     * @ORMId
     * @ORMManyToOne(targetEntity="PLOrderBundleEntityOrder", inversedBy="order_document", cascade={"all"})
     */
    protected $order;
    /**
     * @ORMId
     * @ORMManyToOne(targetEntity="ApplicationSonataMediaBundleEntityMedia", inversedBy="order_document", cascade={"all"})
     */
    protected $media;
}

Order.php

/**
 * @ORMEntity
 * @ORMTable(name="tb_order")
 * @GedmoLoggable
 */
class Order {
    /**
     * @ORMOneToMany(targetEntity="PLOrderBundleEntityOrderHasMedia", mappedBy="order" , cascade={"all"})
     */
    protected $order_document;
}

Media.php

class Media extends BaseMedia {
    /**
     * @var Collection
     * @ORMOneToMany(targetEntity="PLOrderBundleEntityOrderHasMedia", mappedBy="media", cascade={"all"})
     *
     */
    protected $order_document;
}

如果我尝试添加新订单，则会收到此错误：

上下文错误异常： 注意： 未定义的索引： id in /var/www/html/apps/portal_de_logistica/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/BasicEntityPersister.php 685路

错误在哪里？我的映射中出了什么问题？

Answer 1

经过几个小时的头痛，我终于找到了我的错误所在，我想分享以防其他人有同样的问题。解决方案是将@ORMJoinColumn()添加到注释中，所以我现在的代码，仅用于OrderHasMedia实体如下：

/**
 * @var Order
 * @ORMId
 * @ORMManyToOne(targetEntity="PLOrderBundleEntityOrder", inversedBy="order_document", cascade={"all"})
 * @ORMJoinColumn(name="order_no_order", referencedColumnName="no_order")
 */
protected $order;
/**
 * @var Media
 * @ORMId
 * @ORMManyToOne(targetEntity="ApplicationSonataMediaBundleEntityMedia", inversedBy="order_document", cascade={"all"})
 * @ORMJoinColumn(name="media__media_id", referencedColumnName="id")
 */
protected $media;

这就解决了问题。希望这对其他人有帮助
