Question

我正在尝试在集合中创建文档，但是许多插入似乎无法正常工作。它不会抛出任何错误或其他任何东西，但是数据库中的结果集合为空。

./connect.js

const mongoose = require('mongoose');
const uri =
  'mongodb://localhost:27017/devices?poolSize=20&w=majority&replicaSet=rs0';

mongoose.connect(uri, {
  useUnifiedTopology: true,
  useNewUrlParser: true,
});

const db = mongoose.connection;

db.on('error', console.error.bind(console, 'Connection error:'));

db.once('open', () => {
  console.log('connected');
});

./model/device.js

const mongoose = require('mongoose');
const { Schema } = mongoose;

const DeviceSchema = new Schema(
  {
    name: { type: String, required: true },
    serial_number: { type: Number, unique: true, required: true },
    capability: { type: String, required: true },
    created_at: { type: Date, required: true },
    updated_at: { type: Date, required: true },
  },
  {
    collection: 'device',
    strict: 'throw',
  }
);

module.exports = mongoose.model('Device', DeviceSchema);

./populateDevice.js

const Device = require('../model/device');
const config = require('../config');
const {
  serialNumberByDeviceType: {
    temperature: temperatureSerialNumnber,
    humidity: humiditySerialNumnber,
  },
} = config;

Device.insertMany([
  {
    name: 'Temperature Device',
    serial_number: temperatureSerialNumnber,
    capability: 'temperature',
    created_at: 1602764995055,
    updated_at: 1602764995055,
  },
  {
    name: 'Humidity Device',
    serial_number: humiditySerialNumnber,
    capability: 'humidity',
    created_at: 1602765017160,
    updated_at: 1602765017752,
  },
])
  .then(() => console.log('Data inserted.'))
  .catch((error) => console.log(error));

首先我运行node connect.js 输出中的输出是：

connected

然后我运行node populateDevice.js 然后在执行脚本后清除控制台。数据库的实际集合不包含任何文档。

能帮我吗？谢谢。

insertMany不在集合中创建文档
