更正 JSON API 中的空关系
Correct null relationship in JSON API
我有一个JSON API类型的关系
relationships {
fruit: {data: {id: 123, type: "fruits"}}
}
实例没有水果关系怎么办?
我应该这样做吗
relationships {
fruit: {data: {id: null, type: "fruits"}}
}
或这个
relationships {
fruit: {data: null}
}
或这个
relationships {
fruit: null
}
还是完全不同的东西?
根据规范,资源链接对象可能具有以下值:
Resource linkage MUST be represented as one of the following:
- null for empty to-one relationships.
- an empty array ([]) for empty to-many relationships.
- a single resource identifier object for non-empty to-one relationships.
- an array of resource identifier objects for non-empty to-many relationships.

仅来自您的示例
"relationships": {
"fruit": {
"data": null
}
}
根据 JSON:API 规范, 是有效的 relationship object。
这个关系对象告诉您的客户
- resource object有关系
fruit
,
- 这是一对一关系,
- 并且没有任何相关资源。
