在平均堆栈controller.js文件中找不到更新时间ID

Question

我正在开发一个平均堆栈应用程序，并且该应用程序我开发了一个模块并执行CURD操作，每当我更新记录时间获取值并更改表格值时，我单击更新该时间而不更新记录并给我错误< / p>

TypeError: Cannot read property 'id' of undefined

1）这是我的controller.js文件：

import mongoose from 'mongoose';
export const updatePatients = (req,res) => {


Patients.findOneAndUpdate({ _id:req.body.id }, req.body, { new:true }, (err,patients) => {
    if(err){
    return res.json({'success':false,'message':'Some Error','error':err});
    }
    console.log(patients);
    return res.json({'success':true,'message':'Patients Updated Successfully',patients});
  })
}

2）这是我的route.js文件

import express from 'express';

//import controller file
import * as patientsController from '../controllers/patients.server.controller';

// get an instance of express router
const router = express.Router();

router.route('/')
     .get(patientsController.getPatients)
     .post(patientsController.addPatient)
     .put(patientsController.updatePatients);

router.route('/:id')
      .get(patientsController.listPatient)
      .delete(patientsController.deletePatients);


export default router;

3）这是我的modal.js文件

import mongoose from 'mongoose';

var Schema = mongoose.Schema({
  createdAt:{
    type: Date,
    default: Date.now
  },
  titleofuser: {
    type: String,
    default: ''
  },
  fname: {
    type: String,
    default: '',
    required: 'Please fill Patient First name',
    trim: true
  },
  mname: {
    type: String,
    default: ''
  },
  lname: {
    type: String,
    default: '',
    required: 'Please fill Patient Last name',
    trim: true
  },
  knownperson: {
    type: String,
    default: ''
  },
  gender: {
    type: String,
    default: ''
  },
   dateofbirth:{
    type: Date,
    default: '',
    required: 'Please Select Patient Date Of Birth',
    trim: true
  },
  nhs_no: {
    type: Number,
    default: ''
  },
  profile: {
    type: String,
    default: ''
  },
  care_home: {
    type: String,
    default: '',
    required: 'Please Select Patient Care Home Name',
    trim: true
  },
  store_name:{
    type: String,
    default: '',
    required: 'Please Select Patient Care Store',
    trim: true
  },
  room_no:{
     type: Number,
    default: ''
  },
  addmission:{
     type: Date,
    default: '',
  },
  on_warfarin:{
     type: Boolean,
    default: false,
  },
  on_insulin:{
     type: Boolean,
    default: false,
  },
  on_covert_meds:{
     type: Boolean,
    default: false
  },
  service_notes :{
     type: String,
    default: '',
  },
  keyworker:{
     type: String,
    default: '',
  },
  doctor:{
    type:String,
    default:'',
    required:'Please Select Doctor Name',
    trim:true,
  },
  nurse:{
    type:String,
    default:''
  },
  pnurse:{
    type:String,
    default:''
  },
  consultant:{
    type:String,
    default:''
  } 

});

export default mongoose.model('Patients', Schema);

4）这是我的主要app.js文件

import express from 'express';
import path from 'path';
import bodyParser from 'body-parser';
import logger from 'morgan';
import mongoose from 'mongoose';
import SourceMapSupport from 'source-map-support';

// import routes
import patientsRoutes from './routes/patients.server.route';

// define our app using express
const app = express();

// allow-cors
app.use(function(req, res, next) {
    res.header('Access-Control-Allow-Origin', '*');
    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,PATCH,OPTIONS');
    res.header('Access-Control-Allow-Headers', 'Content-Type, Authorization, Content-Length, X-Requested-With');
    // allow preflight
    if (req.method === 'OPTIONS') {
        res.sendStatus(200);
    } else {
        next();
    }
});

// express-busboy to parse multipart/form-data and x-www-form-urlencoded both
//  bb.extend(app);

// configure app
app.use(logger('dev'));
app.use(express.static(path.join(__dirname, 'public')));


// set the port
const port = process.env.PORT || 3001;

// connect to database
mongoose.Promise = global.Promise;
mongoose.connect('mongodb://localhost/NeviMeds', {
  useMongoClient: true,
});

// add Source Map Support
SourceMapSupport.install();

app.use('/apiforpatients' , patientsRoutes);

app.get('/', (req,res) => {
  return res.end('Api working');
})

// catch 404
app.use((req, res, next) => {
  res.status(404).send('<h2 align=center>Page Not Found!</h2>');
});



// start the server
app.listen(port,() => {
  console.log(`App Server Listening at ${port}`);
});

请输入我如何更改更新功能
