Symfony / API平台-多对多关系仅以一种方式起作用

如何解决Symfony / API平台-多对多关系仅以一种方式起作用

我正在一个项目中，我需要将“文章”和“地址”实体关联到“ FAQ”实体。所以我在我的常见问题实体中写下了这两个关系

/**
 * @ORM\ManyToMany(targetEntity=Article::class,inversedBy="faqs")
 * @Groups({"api_backend"})
 * @MaxDepth(1)
 */
private $article;

/**
 * @ORM\ManyToMany(targetEntity=Adresse::class,inversedBy="faqs")
 * @Groups({"api_backend"})
 * @MaxDepth(1)
 */
private $address;

并将这些属性添加到我的Adresse.php 

/**
 * @ORM\ManyToMany(targetEntity=Faq::class,mappedBy="address")
 * @Groups({"api_backend"})
 * @MaxDepth(1)
 */
private $faqs;

和Article.php 

/**
 * @ORM\ManyToMany(targetEntity=Faq::class,mappedBy="article")
 * @Groups({"api_backend"})
 * @MaxDepth(1)
 */
private $faqs;

当我尝试将一篇文章添加到我的常见问题解答中时，效果很好

Postman Request

[2020-10-27 03:31:50] doctrine.DEBUG: "START TRANSACTION" [] []
[2020-10-27 03:31:50] doctrine.DEBUG: UPDATE faq SET enabled = ? WHERE id = ? [true,3] []
[2020-10-27 03:31:50] doctrine.DEBUG: INSERT INTO faq_article (faq_id,article_id) VALUES (?,?) [3,352] []
[2020-10-27 03:31:50] doctrine.DEBUG: "COMMIT" [] []

但是当我尝试添加地址时，它就被忽略了，没有任何错误

Postman Request

[2020-10-27 03:41:18] doctrine.DEBUG: "START TRANSACTION" [] []
[2020-10-27 03:41:18] doctrine.DEBUG: UPDATE faq SET enabled = ? WHERE id = ? [true,3] []
[2020-10-27 03:41:18] doctrine.DEBUG: "COMMIT" [] []

与我的关系没有任何关系显示在日志中，并且该关系也没有在数据库中更新。

有趣的是，它在另一个方向上很好用，但是我不能在我的应用程序中使用它。

Postman Request

[2020-10-27 03:45:07] doctrine.DEBUG: "START TRANSACTION" [] []
[2020-10-27 03:45:08] doctrine.DEBUG: INSERT INTO faq_adresse (faq_id,adresse_id) VALUES (?,16] []
[2020-10-27 03:45:08] doctrine.DEBUG: "COMMIT" [] []

如果我在数据库中手动添加该关系，则在获得我的常见问题实体后就能看到它

有人知道吗？我真的被卡在这里

编辑：我在该项目上安装了旧版easy_admin，并且一切正常，因此api平台方面确实存在问题。
