这是之前在 SO 上发布的有关 react-relay 突变警告的此答案的后续问题。

“在您的情况下，您需要做的是将 FeatureLabelNameMutation getFragment 添加到您的 AddCampaignFeatureLabelMutation 查询中。”

与该问题中的 OP 一样，我也想进行嵌套中继突变，并且我已经尝试按照 @Christine 的建议进行操作，但我不确定将getFragment部件放在哪里。

在我的应用程序中，我想在用户创建任务时创建一个带有多个嵌套“子任务”的“任务”。

我尝试过的工作有效，但我没有得到AddSubTaskMutation突变的返回 PayLoad 。这是我迄今为止尝试过的：

添加TaskMutation.js

export default class AddTaskMutation extends Relay.Mutation {
  static fragments = {
    classroom: () => Relay.QL`
      fragment on Classroom { 
        id,
        tasks(last: 1000) {
          edges {
            node {
                id,
                ${AddSubTaskMutation.getFragment('task')}, //<-- what I tried adding 
            },
          }
        },
      }`,
    }`,
  };
  ...

添加SubTaskMutation.js

export default class AddSubTaskMutation extends Relay.Mutation {
  static fragments = {
    task: () => Relay.QL`
      fragment on Task { 
        id,
      }`,
   };
   ...

任务创建.js

Relay.Store.update(
  new AddTaskMutation({
    title,
    instruction,
    start_date,
    end_date,
    published: isPublished,
    classroom: this.props.classroom
  }),
  {
    onSuccess: (response) => {
      let {taskEdge} = response.addTask;
      for (let subTask of this.state.subTaskContent) {
        Relay.Store.update(
          new AddSubTaskMutation({
            task: taskEdge.node,
            type: subTask['type'],
            position: subTask['position'],
            ...
          }),
        );
      }
    }
  }
)
...
export default Relay.createContainer(TaskCreate, {
  prepareVariables() {
    return {
      limit: Number.MAX_SAFE_INTEGER || 9007199254740991,
    };
  },
  fragments: {
    classroom: () => Relay.QL`
      fragment on Classroom {
        id,
        tasks(last: $limit) {
          edges {
            node {
              id,
              ...
            }   
          }
        },
        ...
        ${AddTaskMutation.getFragment('classroom')},
      }
    `,
  },
});

除了没有获得有效载荷之外，我还收到以下警告：

Warning: RelayMutation: Expected prop `task` supplied to `AddSubTaskMutation` to be data fetched by Relay. This is likely an error unless you are purposely passing in mock data that conforms to the shape of this mutation's fragment.
Warning: writeRelayUpdatePayload(): Expected response payload to include the newly created edge `subTaskEdge` and its `node` field. Did you forget to update the `RANGE_ADD` mutation config?

所以我的问题是：我在哪里添加getFragment进去AddTaskMutation.js才能完成这项工作？
