在graphQL中提交对象数组作为查询变量 [英] Submit an array of objects as a query variable in graphQL

问题描述

当字段之一是对象数组时，如何构造查询参数graphQL突变?当我对突变进行硬编码时，这是有效的并且有效:

How can I structure the query parameters a graphQL mutation when one of the fields is an array of objects? When I hard-code the mutation this is valid and works:

mutation{
  submitResponse(user: "1234", responses: [{ answerId: "wmtBCWtkSeDs5meBe", selected: false}, { answerId: "wmtBCWtkSeDs5meBz", selected: true}]) {
    id
  }
}

我一辈子都想不通如何为对象的响应数组传递查询参数.如何定义对象中每个字段的类型.这就是用户ID所需的，并且可以正常工作，但我无法弄清楚它的响应内容.

I can't for the life of me figure out how to pass in query parameters for the responses array of objects. How can I define the type of each field in the object. This is what it would like for the user id and that works fine but I can't figure out the responses piece of it.

mutation submitResponse($user: ID!){
  submitResponse(user: $user, responses: [{ answerId: "wmtBCWtkSeDs5meBe", selected: false}, { answerId: "wmtBCWtkSeDs5meBz", selected: true}]) {
    id
  }
}

谢谢！

推荐答案

我知道这个问题很旧，但是也许其他人需要简单的解决方案.

I know that the question is old, but maybe someone else needs simple solution.

1. 将responses的类型设置为String!

mutation submitResponse($user: ID!, $responses: String!){
  submitResponse(user: $user, responses: $responses) {
    id
  }
}

然后:

Then:

yourData = [{ answerId: "wmtBCWtkSeDs5meBe", selected: false}, { answerId: "wmtBCWtkSeDs5meBz", selected: true}]
responses = JSON.stringify(yourData)

对于我在BackEnd中的情况，我使用Python，因此在BackEnd中接收responses，然后将JSON(字符串)简单地转换为Python的字典，就像这样:

In my case in BackEnd I use Python, so receive responses in BackEnd and then simply convert JSON (string) to Python's dict, something like:

import json
responses = json.loads(input.get('responses'))
