MongoDb聚合条件组和推送记录

Question

我正在尝试运行一个条件组并进行推送。我不知道\xe2\x80\x99t 是否可以使用 MongoDb 聚合或 NodeJs。

\n

我有出勤收集和轮班收集，如下所示。还为我当前的尝试创建了 Playground Mongo Playground。

[\n    {\n      "_id": "626965ee9a6fe1422b61d4b1",\n      "employee": "6220624b3b2eaac4b15d42e8",\n      "date": "2022-04-28",\n      "name": "Day",\n      "isNight": false\n    },\n    {\n      "_id": "626965ee9a6fe1422b61d4b2",\n      "employee": "622062023b2eaac4b15d42e6",\n      "date": "2022-04-30",\n      "name": "Night",\n      "isNight": true\n    },\n    {\n      "_id": "626965ee9a6fe1422b61d4b3",\n      "employee": "622062023b2eaac4b15d42e6",\n      "date": "2022-05-01",\n      "name": "Night",\n      "isNight": true\n    }\n  ]\n

我的要求是，如果isNight === true然后将下一个考勤记录推到上一个日期。

\n

我所需的 JSON 应该如下所示。

我该如何使用 MongoDb 或 NodeJs？

脚本.js

要进行更改的node.js 脚本。

let yourData = require('./DB.json')

// 1 Console output
console.log(yourData[1].shifts);

for (let index in yourData) {
    if (yourData[index].shifts[0].isNight) {
        yourData[index].shifts[0].date = yourData[index].attendances[1].createdAt.split("T")[0];
    }
}

// 2 Console output
console.log(yourData[1].shifts);
