【问题描述】：

我正在尝试将对象数组保存到猫鼬模式，但无法将数据加载到laptop 模式中，我只看到一个包含id 的插入。 如何将 json 对象数组保存到猫鼬模式？

controller.js

var laptopData = [
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'HP',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'HP',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp',
 name: 'Hp probook 15.1',cpu:'2.4GHZ' ,ram: '4GB', harddrive: '160GB',Brand:'Hp'
]
var laptop = new Laptop(laptopData);
laptop.save(function(err) 
  // we've saved the dog into the db here
  if (err) throw err;

);

schema.js

'use strict';

var mongoose = require('bluebird').promisifyAll(require('mongoose'));

var LaptopSchema = new mongoose.Schema(
  name: String,
  ram:String,
  harddrive:String,
  Brand: String
);

module.exports = mongoose.model('Laptop', LaptopSchema);

【参考方案1】：

您应该单独创建对象并保存它们。你不能传递这样的数组。在行中使用一些东西

var laptopData = [...];
for(var laptopItem in laptopData)
    new Laptop(laptopData[laptopItem])
      .save()
      .catch((err)=>
        console.log(err.message);
      );
