模型中我的datasets.js就是这样

var mongoose = require("mongoose");

// Declare schema
var datasetSchema = new mongoose.Schema({
    owner_name: {type: String, required: true},
    RFDeviceId: {type: String, required: true, index: {unique: true}},
    coordinates: {type: Number, required: true},
    CoordinatesTime: {type: String, required: true},
    speed: {type: String, required: true},
    sat_tracked: {type: Number, required: true},
    gps_fix_type: {type: Number, required: true},
    temperatureata: {type: Number, required: true},
    humidity: {type: Number, required: true}, 
    bat_v: {type: Number, required: true},
    bat_p: {type: Number, required: true}
});

// Export schema
mongoose.model("Dataset", datasetSchema);```

以及路由中的my dataset.js

/* CRUD API */

如果我设置了required:false expect with owner\u name，那么它发送的第一个数据发送时间

MongoError:E11000重复键错误集合：test.datasets index:index\u 1 dup key:{:null}

当您创建模型中所需的所有字段时，请大家非常高兴地帮助它。

。因此，无论何时创建任何数据集，都需要提供所有必需字段的数据

在创建数据集查询API中，首先直接将req.body.[field value]分配给一个新变量，该变量也复制了该原始变量的引用

删除原始变量时，复制的变量也会丢失其值并设置为“未定义”。 现在，您的创建查询如下所示：

// POST new dataset request
router.post("/", helper.authenticate, function(req, res) {
    // Used to set the dataset owner
    var sessionUser = req.session.user.name;
    // Get values from the post request
    var RFDeviceId = req.body.RFDeviceId;
    var coordinates = req.body.coordinates;
    var CoordinatesTime = req.body.CoordinatesTime;
    var speed = req.body.speed;
    var sat_tracked = req.body.sat_tracked;
    var gps_fix_type = req.body.gps_fix_type;
    var temperatureata = req.body.temperatureata;
    var humidity = req.body.humidity;
    var bat_v = req.body.bat_v;
    var bat_p = req.body.bat_p;

    // This is so that we can loop through the object in reverse order
    // We do that so that the fields are saved in the right order on the db
    // (this way it will appear in the right order on the 'edit' view)
    var propertiesList = [];
    for (var property in req.body) {
        if (req.body.hasOwnProperty(property)) {
            propertiesList.push(property);
        }
    }
    propertiesList.reverse();

    var variablesFields = {};
    for (var i in propertiesList) {
        console.log(propertiesList[i])
        variablesFields[propertiesList[i]] = {name:req.body[propertiesList[i]],
                                    values: Array}; 
    }

    // Create dataset 
    Dataset.create({
        RFDeviceId: RFDeviceId,
        coordinates: coordinates, 
        CoordinatesTime: CoordinatesTime,
        speed: speed,
        sat_tracked: sat_tracked,
        gps_fix_type: gps_fix_type,
        temperatureata: temperatureata,
        humidity: humidity,
        bat_v: bat_v,
        bat_p: bat_p,
        owner_name: sessionUser
    }, function(err, dataset) {
        if (err) {
            console.log("Error creating the dataset: " + err);
            req.session.error = "A problem occured when creating the dataset. Please try again.";
        } else {
            console.log("New dataset created with id: " + dataset._id);
            req.session.success = "Dataset " + "name" + " created successfully.";
        }
        res.redirect("/index");
    });
});

我希望你有正确做这件事的想法
