Doctrine2 OneToOne映射中给出的ID错误

Question

我现在正在认真处理OneToOne映射出现的问题。

让我展示一下我目前拥有的：

OrderItem实体

/**
 * OrderItem
 *
 * @ORMTable(name="order_item")
 * @ORMEntity
 */
class OrderItem
{
    /**
     * @var integer
     *
     * @ORMColumn(type="integer")
     * @ORMId
     * @ORMGeneratedValue(strategy="IDENTITY")
     */
    private $id;
    // ... //
    /**
     * @ORMOneToOne(targetEntity="UserPricingOption", mappedBy="orderItem")
     */
    private $userPricingOption;
    /**
     * @ORMManyToOne(targetEntity="Order", inversedBy="items")
     * @ORMJoinColumn(referencedColumnName="id")
     */
    private $order;
    // ... //

UserPricingOption实体

/**
 * UserPricingOption
 *
 * @ORMTable(name="user_pricing_option")
 * @ORMEntity
 * @ExclusionPolicy("all")
 */
class UserPricingOption
{
    /**
     * @var integer
     *
     * @ORMColumn(type="integer")
     * @ORMId
     * @ORMGeneratedValue(strategy="IDENTITY")
     */
    private $id;
    // ... //
    /**
     * @ORMOneToOne(targetEntity="OrderItem", inversedBy="userPricingOption")
     * @ORMJoinColumn(referencedColumnName="id")
     */
    private $orderItem;
    // ... //

因此生成的表如下所示：

order_item表

 * `id` 5

user_pricing_option表

 * `id` 12
 * `order_item_id` 5

所以现在我正在尝试做以下事情：

echo $orderItem->getId(); // gives 5, `GOOD`
echo $orderItem->getUserPricingOption()->getId(); // gives 5 `BAD` (completely different user_pricing_option row),  it should return 12.

我真的不知道为什么，请找到原始的条令查询：请记住，查询包含的信息比上面显示的示例多得多

SELECT t0.id AS id_1, t0.guid AS guid_2, t0.created_at AS created_at_3, t0.modified_at AS modified_at_4, t5.id AS id_6, t5.guid AS guid_7, t5.created_at AS created_at_8, t5.modified_at AS modified_at_9, t5.user_id AS user_id_10, t5.order_item_id AS order_item_id_11, t5.pricing_option_id AS pricing_option_id_12, t13.id AS id_14, t13.guid AS guid_15, t13.created_at AS created_at_16, t13.modified_at AS modified_at_17, t13.user_id AS user_id_18, t13.order_item_id AS order_item_id_19, t13.product_variant_id AS product_variant_id_20, t0.order_invoice_id AS order_invoice_id_21, t0.order_id AS order_id_22 FROM order_item t0 LEFT JOIN user_pricing_option t5 ON t5.order_item_id = t0.id LEFT JOIN user_product_variant t13 ON t13.order_item_id = t0.id WHERE t0.order_id = ? [131]

所以基本上$orderItem->getUserPricingOption()->getId()总是返回与$orderItem->getId(); 相同的ID

有人可能看到发生了什么？

OneToOne双向？尝试在joinColumn中定义要引用id的列的名称。

/**
     * @ORMOneToOne(targetEntity="OrderItem", inversedBy="userPricingOption")
     * @ORMJoinColumn(name="order_item_id", referencedColumnName="id")
     */
    private $orderItem;
