在GraphQL中检索对象ID [英] Retrieve the object ID in GraphQL

问题描述

我想知道是否有可能获得对象的原始ID"作为查询结果.每当我向服务器发出请求时，它都会返回节点全局标识符"，类似于 U29saWNpdGFjYW9UeXBlOjEzNTkxOA == .

I'd like to know whether it is possible to get the "original id" of an object as the result of the query. Whenever I make a request to the server, it returns the node "global identifier", something like U29saWNpdGFjYW9UeXBlOjEzNTkxOA== .

查询与此类似:

{
  allPatients(active: true) {
    edges {
      cursor
      node {
        id
        state
        name
      }
    }
  }

，返回值为:

{
  "data": {
      "edges": [
        {
          "cursor": "YXJyYXljb25uZWN0aW9uOjA=",
          "node": {
            "id": "U29saWNpdGFjYW9UeXBlOjEzNTkxOA==",
            "state": "ARI",
            "name": "Brad"
          }
        }
      ]
  }
}

如何获取数据库级别的对象的原始" ID(例如"112")而不是该节点的唯一标识符?

How can I get the "original" id of the object at the database level (e.g. '112') instead of that node unique identifier?

ps .:我在服务器端使用了graphene-python和Relay.

ps.: I am using graphene-python and Relay on the server side.

推荐答案

在Node对象中覆盖默认的to_global_id方法对我来说是可行的:

Overriding default to_global_id method in Node object worked out for me:

class CustomNode(graphene.Node):
    class Meta:
        name = 'Node'

    @staticmethod
    def to_global_id(type, id):
        return id


 class ExampleType(DjangoObjectType):
     class Meta:
         model = Example
         interfaces = (CustomNode,)
