【问题描述】：

我正在尝试将模型保存到 mongodb。虽然它没有显示任何错误，但实例没有被保存到 db。对象正在正确填充，您可以看到控制台的输出。可能是什么问题？

Model
------
const mongoose = require('mongoose');
const config = require('../config/database');
const HospitalSchema = mongoose.Schema(
    name:type:String,required:true,
    specialization:type:String,required:true,
    location:type:String,required:true,
    address:type:String,required:true,
    pointOfContact:[
        name:type:String,required:true,
        phone:type:String,required:true
    ]
)
const Hospital = module.exports = mongoose.model('Hospital',HospitalSchema);
module.exports.addHospital = function(hospital,callback)
    console.log(hospital);
    hospital.save(callback);



controller
----------
router.post('/hospital/addHosp',(req,res)=>
  console.log(req.body);
  let hospital = new Hospital(
    name:req.body.hosp.name,
    specialization:req.body.hosp.specialization,
    location:req.body.hosp.location,
    address:req.body.hosp.completeAddress,
    pointOfContact:req.body.hosp.pointOfContact,
);

Hospital.addHospital(hospital,(err,hosp)=>
  (err)=>console.log(err);res.json(success:false,msg:'failed to add hospital'),
  (hosp)=>res.json(success:true,msg:'successfully added hospital')
)

)

模型中addHosp函数中console.log的输出：

 _id: 5d3806a53b0d4215ac6bac53,
  name: 'h',
  specialization: 's',
  location: 'l',
  pointOfContact:
   [  _id: 5d3806a53b0d4215ac6bac54, name: 'n', phone: '99999'  ] 

【问题讨论】：

试试 hospital.save();，没有回调..

hospital.save() 没有解决问题，但告诉我错误在哪里。谢谢。所以发生错误是因为我没有从前端正确传递医院地址。

我很高兴你能解决这个问题...... :)

【参考方案1】：

像这样更新你的函数：

module.exports.addHospital = function(hospital,callback)
    var hosp = new Hospital(hospital)
    console.log(hosp);
    hosp.save(callback);
