Node.js Mongoose不保存数组元素

我不熟悉Node和Mongoose，我正在尝试使用MERN堆栈构建一个应用程序

当我使用mongoose将数据从我的状态保存到mongodb时，我试图保存的数组的内容实际上不会被保存

这就是我的测试数据从客户端发送到服务器时的样子：

当我查看Mongodb Atlas时，它看起来是这样的：

那里的阵列似乎是空的

相应的模型如下所示：

const mongoose = require("mongoose");

const Schema = mongoose.Schema;
const LanesSchema = new Schema(
    {
        lanes: [
            {
                id: String,
                title: String,
                tasks: [
                    {
                        id: String,
                        title: String,
                        status: String,
                        description: String,
                        priority: String
                    }
                ]
            }
        ]
    },
    { minimize: false }
);

const Lane = mongoose.model("Lanes", LanesSchema);

module.exports = Lane;

const express = require("express");

const router = express.Router();

const Lane = require("../models/lanes");

router.post("/save", (req, res) => {
    const data = req.body;
    const newLane = new Lane(data);
    newLane.save(error => {
        if (error) {
            res.status(500).json({ msg: "Internal server error" });
            return;
        }
        res.json({
            msg: "We received your data!"
        });
    });
});

module.exports = router;

router.post("/save", (req, res) => {
    const data = req.body;
    const newLane = new Lane();
    newLane.collection.insertMany(data, err => {
        if (err) {
            console.log(err);
        } else {
            console.log("Multiple docs inserted");
        }
    });
});

我想这里的模型可能有问题，但我不确定

我也在这里尝试了这个版本，但也不起作用：

const LanesSchema = new Schema([
    {
        id: String,
        title: String,
        tasks: [
            {
                id: String,
                title: String,
                status: String,
                description: String,
                priority: String
            }
        ]
    }
]);

代码的保存部分基本上如下所示：

const mongoose = require("mongoose");

const Schema = mongoose.Schema;
const LanesSchema = new Schema(
    {
        lanes: [
            {
                id: String,
                title: String,
                tasks: [
                    {
                        id: String,
                        title: String,
                        status: String,
                        description: String,
                        priority: String
                    }
                ]
            }
        ]
    },
    { minimize: false }
);

const Lane = mongoose.model("Lanes", LanesSchema);

module.exports = Lane;

const express = require("express");

const router = express.Router();

const Lane = require("../models/lanes");

router.post("/save", (req, res) => {
    const data = req.body;
    const newLane = new Lane(data);
    newLane.save(error => {
        if (error) {
            res.status(500).json({ msg: "Internal server error" });
            return;
        }
        res.json({
            msg: "We received your data!"
        });
    });
});

module.exports = router;

router.post("/save", (req, res) => {
    const data = req.body;
    const newLane = new Lane();
    newLane.collection.insertMany(data, err => {
        if (err) {
            console.log(err);
        } else {
            console.log("Multiple docs inserted");
        }
    });
});

这是格式为JSON的req.body：

[
   {
      "id":"1",
      "title":"Open",
      "tasks":[
         {
            "id":"1",
            "title":"Test task",
            "status":"Open",
            "description":"Test description",
            "priority":"High"
         },
         {
            "id":"4",
            "title":"Test task 4",
            "status":"Open",
            "description":"Test description",
            "priority":"Normal"
         }
      ]
   },
   {
      "id":"2",
      "title":"In Progress",
      "tasks":[
         {
            "id":"2",
            "title":"Test task 2",
            "status":"In Progress",
            "description":"Test description",
            "priority":"Normal"
         },
         {
            "id":"3",
            "title":"Test task 3",
            "status":"In Progress",
            "description":"Test description",
            "priority":"Normal"
         }
      ]
   },
   {
      "id":"b0d547b1-f669-418e-8558-4739b15e1ef6",
      "title":"testLane",
      "tasks":[

      ]
   }
]

现在我不确定问题出在哪里。到目前为止，我还没有找到类似的问题

如果我丢失了可能是问题原因的部分代码，请让我知道

提前感谢。

谢谢@sushant mehta的评论

您正在尝试添加多个条目，但正在使用“保存”，请尝试使用insertMany

这帮我完成了任务

我的代码现在如下所示：

const mongoose = require("mongoose");

const Schema = mongoose.Schema;
const LanesSchema = new Schema(
    {
        lanes: [
            {
                id: String,
                title: String,
                tasks: [
                    {
                        id: String,
                        title: String,
                        status: String,
                        description: String,
                        priority: String
                    }
                ]
            }
        ]
    },
    { minimize: false }
);

const Lane = mongoose.model("Lanes", LanesSchema);

module.exports = Lane;

const express = require("express");

const router = express.Router();

const Lane = require("../models/lanes");

router.post("/save", (req, res) => {
    const data = req.body;
    const newLane = new Lane(data);
    newLane.save(error => {
        if (error) {
            res.status(500).json({ msg: "Internal server error" });
            return;
        }
        res.json({
            msg: "We received your data!"
        });
    });
});

module.exports = router;

router.post("/save", (req, res) => {
    const data = req.body;
    const newLane = new Lane();
    newLane.collection.insertMany(data, err => {
        if (err) {
            console.log(err);
        } else {
            console.log("Multiple docs inserted");
        }
    });
});

你能将你的req.body作为json添加到问题中吗？@SuleymanSah我添加了req.body。它必须是JSON吗？最好是JSON格式，这样我们可以将它与模式进行比较。@SuleymanSah好的，我明白了。我又更新了我的帖子。感谢您的帮助。您正在尝试添加多个条目，但正在使用“保存”，请尝试使用insertMany。
