How to add a new object with AngularJS and mongoDB - angularjs

Question

I'm using NodeJS, ANgularJS, and MongoDB with mongoose to make a website. I'm having some trouble adding an object in mongoDB. The name of the object is Todo.
Here are the models of Todo:
var mongoose = require('mongoose');
var TodoSchema = new mongoose.Schema({
name: String,
password : String,
completed: Boolean,
note: String
});
module.exports = mongoose.model('Todo', TodoSchema);
In the controller I create a new Todo and push it
angular.module('app').controller('Connexion', ['$scope', 'Todos','$location', function($scope,Todos, $location) {
$scope.editing = [];
$scope.todos = Todos.query();
$scope.save = function() {
var todo = new Todos({ name: "test", password: "test", completed: false });
$scope.todos.push(todo);
Todos.save($scope.todo);
}
}]);
This is my html page, each time I click on the button I Have a new todo created and it's displayed on screen:
<button ng-click="save()">Creer POST </button>
<ul>
<li ng-repeat="todo in todos">
{{todo.name}}
{{todo.password}}
</li>
</ul>
But I have a problem, the new object is not added on the database. How can I do it?
This is my files in the back-end :
var express = require('express');
var router = express.Router();
var mongoose = require('mongoose');
var Todo = require('../models/Todo.js');
/* GET /todos listing. */
router.get('/', function(req, res, next) {
Todo.find(function (err, todos) {
if (err) return next(err);
res.json(todos);
});
});
/* POST /todos */
router.post('/', function(req, res, next) {
Todo.create(req.body, function (err, post) {
if (err) return next(err);
res.json(post);
});
});
/* GET /todos/id */
router.get('/:id', function(req, res, next) {
Todo.findById(req.params.id, function (err, post) {
if (err) return next(err);
res.json(post);
});
});
/* PUT /todos/:id */
router.put('/:id', function(req, res, next) {
Todo.findByIdAndUpdate(req.params.id, req.body, function (err, post) {
if (err) return next(err);
res.json(post);
});
});
/* DELETE /todos/:id */
router.delete('/:id', function(req, res, next) {
Todo.findByIdAndRemove(req.params.id, req.body, function (err, post) {
if (err) return next(err);
res.json(post);
});
});
module.exports = router;
And if this can help this the back-end file app.js
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var mongo = require('mongodb');
var Post = require('./models/Post.js');
var routes = require('./routes/index');
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/todoApp', function(err) {
if(err) {
console.log('connection error', err);
} else {
console.log('connection successful');
}
});
var app = express();
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', function(req, res, next){
res.sendFile(__dirname + '/public/index.html');
});
var found = ['DB Connection not yet established. Try again later. Check the console output for error messages if this persists.'];
module.exports = app;

Answer 1

$scope.todo from Todos.save($scope.todo); is not defined so this is why you might not manage to save anything
