Question

我有两个实体

Quote和QuoteProduct之间具有OneToMany关系。

当我执行PUT请求以更新嵌入式QuoteProduct关系时，它将始终删除所有项并将其添加，直到结果生成新ID。

根据官方文档https://api-platform.com/docs/core/serialization/#denormalization 我应该可以通过传递他的ID来更新特定项目

获取报价请求/ fbe01952-2a23-4882-bb9f-970e8598f979

结果：

{
  "@context": "\/contexts\/Quote",
  "@id": "\/quotes\/fbe01952-2a23-4882-bb9f-970e8598f979",
  "@type": "Quote",
  "products": [
    {
      "@id": "\/quote_products\/15216edd-dd5c-49d5-bf3f-39d389d804d6",
      "@type": "QuoteProduct",
      "code": "Code 1",
      "quote": "\/quotes\/fbe01952-2a23-4882-bb9f-970e8598f979"
    }
  ]
}

提出报价请求/ fbe01952-2a23-4882-bb9f-970e8598f979 JSON参数（请注意，我更改了QuoteProduct代码属性的值）

{
  "@context": "\/contexts\/Quote",
  "@id": "\/quotes\/fbe01952-2a23-4882-bb9f-970e8598f979",
  "@type": "Quote",
  "products": [
    {
      "@id": "\/quote_products\/15216edd-dd5c-49d5-bf3f-39d389d804d6",
      "@type": "QuoteProduct",
      "code": "A new code",
      "quote": "\/quotes\/fbe01952-2a23-4882-bb9f-970e8598f979"
    }
  ]
}

结果为：

{
  "@context": "\/contexts\/Quote",
  "@id": "\/quotes\/fbe01952-2a23-4882-bb9f-970e8598f979",
  "@type": "Quote",
  "products": [
    {
      "@id": "\/quote_products\/865da321-dd74-4a39-82a3-e0e935555262",
      "@type": "QuoteProduct",
      "code": "A new code",
      "quote": "\/quotes\/fbe01952-2a23-4882-bb9f-970e8598f979"
    }
  ]
}

代码已更改，但已生成一个新的@id。

几个小时后，我设法找到答案，我用参数发布了我的请求：

Content-Type : application/json;charset=UTF-8

当我使用Content-Type : application/ld+json时，它会按预期工作

根据API平台文档https://api-platform.com/docs/core/content-negotiation/，这是有道理的：不鼓励使用原始JSON或原始XML格式，请改用JSON-LD，因为它提供了更多功能并且易于使用
