symfony doctrine 鉴别器错误序列化器

Question

我使用一个平台开发rest API，现在当我在normalize和denormalize中序列化数据时发现错误。 I use doctrine inheritance for entities, I have class person abstract class content commons attributes and I create class Partner, Participant, and declarant, all classes extend for person class, now when I add groups in Participant class I found error, the error is when我在合作伙伴和声明属性中添加了一个组，它显示，但是当我在属性 class 人员中添加一个组时，class 参与者中的属性不显示

如何显示人员实体的属性和参与者的属性..感谢您的先进

Answer 1

即使 doctrine 很好地支持 inheritance，api-platform 也不支持。

反序列化忽略父 class 属性或子 class 属性。

真正的问题是为什么需要 inheritance？

1. 添加一个新实体 class 链接到 Person？
2. 使用多态性，例如public function heal(Person $person): void {} ？
3. 收集共同属性？

如果是1. ，那你就完蛋了。 例如，假设您要添加Dog class：

/*
 * @ApiResource
 * @ORM\Entity
 */
class Dog
{
    /*
     * @Column
     */
    private $name;

    /*
     * @var Person
     * @ManyToOne(class="Person")
     */
    private $owner;
}

即使使用具体的Person class，序列化也不会按预期工作，IRI 生成不会检测到子 class。 你不会看到像这样的几个Dog实例：

{"name": "Bar", "owner": "/participants/1"}
{"name": "Foo", "owner": "/partners/2"}
{"name": "Dummy", "owner": "/declarants/4"}

Api-platform 将尝试创建包含/persons字符串的 IRI。 获取/persons仅检索 Person 属性。

如果是2. ，您的实体只需要实现一个通用接口，或者您可以使用访问者模式。

如果是3. ，常用的方法是使用doctrine embeddable objects 。 它们支持@Groups注释。
