from nodejs app mongose.save() block and doesn't do anything?

Question

I'm trying to use a very basic MongoDB method is to save a document on a database with mongoose.

1.I installed my MongoDB in centos 7

2.Create a database on the Mongo shell using: use mydatabase and insert a document inside it as normal.

3.Install mongoose and make a connection between my nodejs app and the MongoDB:

mongoose.connect('mongodb://localhost:27017/goClass_test', {
  useUnifiedTopology: true,
  useNewUrlParser: true,
});

4. test the connection and all is fine with:

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

5. Import the model schema as normal:

var { Classe } = require('../DBModels/GoClassDBModels/classes');

6. try to add new document like this:

var newClasse = new Classe({
     label: 'hello',
     level: 'level',
   });

newClasse.save()

My Model is:

const mongoose = require('mongoose');
const { Schema } = require('mongoose');
var ObjectId = mongoose.Schema.Types.ObjectId;

var classSchema = new Schema({
  directeurId: {
    type: ObjectId,
  },
  label: {
    type: String,
  },
  level: {
    type: String,
  },
  studentNbr: {
    type: String,
  },
});

var Classe = mongoose.model('Classes', classSchema);

module.exports = { Classe };

SERVER.JS:

const mongoose = require('mongoose');
const express = require('express');
const bodyParser = require('body-parser');
const http = require('http');
const cookieParser = require('cookie-parser');
const _ = require('lodash');

var app = express();
var server = http.createServer(app);
server.listen(80, () => {
  console.log('server is started on 80');
});

mongoose.connect('mongodb://localhost:27017/goClass_test', {
  useUnifiedTopology: true,
  useNewUrlParser: true,
});

console.log(mongoose.connection.host);
console.log(mongoose.connection.port);

let db = mongoose.connection;

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

db.on('error', (err) => {
  console.log(err);
});

var { Classe } = require('../DBModels/GoClassDBModels/classes');

const goClasseRouteDirecteur = require('./GOClassRoutes/DirecteurRoutes/subRoutesClass');

app.use(bodyParser.json());
app.use(cookieParser(['lakkini.com']));
app.use(
  bodyParser.urlencoded({
    extended: false,
  })
);

app.use(function (req, res, next) {
  res.set(
    'Cache-Control',
    'no-cache, private, no-store, must-revalidate, max-stale=0, post-check=0, pre-check=0'
  );
  next();
});

app.set('view engine', 'hbs');
app.use(express.static('/home/admin/SMS'));
app.use(express.static('/home/admin/assets'));

app.get('/', (req, res) => {
  res.render('SMS/dashboard.hbs');
});

app.get('/classes', (req, res) => {
  res.render('SMS/classes.hbs');
});

app.get('/inscription', (req, res) => {
  res.render('SMS/inscriptions.hbs');
});

app.post('/saveClasse', (req, res) => {
  var newClasse = new Classe({
    label: 'hello',
    level: 'level',
  });
  console.log('im gonna save the new class');
  newClasse.save((err, response) => {
    if (err) console.log(err);
    else console.log(response);
  });
});

The problem is: nothing happened. No document has been inserted and no errors. Can you suggest to me, please ?

PS: I'm trying to request from an HTTP server without HTTPS.

will that affect my requests nd block the save to the database?

result: click to see the picture of the result please

Answer 1

I found the issue, but I don't understand why that. the first structure was:

**

• DBModel
  • classes.js
• Server
  • server.js**

the structure right now:

**

• DBModel

  • classes.js

• server.js

**

I make out the server from that folder and all working fine...??

why that?
