这是一个后续问题这个答案 https://stackoverflow.com/a/34776023/2030321早些时候在 SO 上发布了有关反应中继突变警告的文章。
“在这种情况下，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，我也想进行嵌套的中继突变，并且我已经尝试按照@Christine的建议进行操作，但我不确定到底要在哪里放置getFragment part.
在我的应用程序中，我想在用户创建任务时创建一个具有多个嵌套“子任务”的“任务”。
我尝试过的方法有效，但我没有得到返回的 PayLoadAddSubTaskMutation突变。到目前为止，这是我尝试过的：
AddTaskMutation.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
},
}
},
}`,
}`,
};
...
AddSubTaskMutation.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')},
}
`,
},
});
除了没有获得有效负载之外，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 in AddTaskMutation.js使这项工作有效？
