symfony学说鉴别器错误串行器

Question

我使用一个平台来开发rest API，现在当我在normalize和denormalize中序列化数据时，我发现了一个错误。我对实体使用条令继承，我有类-人抽象类-内容-公共属性，我创建类Partner、Participant和declarant，所有类都为人类扩展，现在当我在Participant类中添加组时，我发现错误，错误是当我在Partner和Declarator属性中添加一个组时，它会显示，但当我还在属性类person中添加一组时，类中的属性参与者未显示

法人实体：

如何显示个人实体的属性和参与者的属性。。

Answer 1

即使条令很好地支持继承，api平台也不支持。

反序列化忽略父类属性或子类属性。

真正的问题是为什么需要继承

1. 添加链接到Person的新实体类
2. 使用多态性，如public function heal(Person $person): void {}
3. 收集共同财产

如果是1.，那你就大错特错了。例如，假设您想添加一个Dog类：

/*
* @ApiResource
* @ORMEntity
*/
class Dog
{
/*
* @Column
*/
private $name;
/*
* @var Person
* @ManyToOne(class="Person")
*/
private $owner;
}

即使有一个具体的Person类，序列化也不会像预期的那样工作，IRI生成不会检测到子类。你不会看到几个Dog这样的例子：

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

Api平台将尝试创建包含/persone字符串的IRI。获取/Person仅检索Person属性。

如果是2.，那么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.，常见的方法是使用条令可嵌入对象。它们支持@Groups注释。
