Data not getting saved in the MongoDB from node.js - json

Question

I want to create the rest api using node.js and mongodb
I am entering all the details and trying it to store it in the mongodb database.
// call the packages we need
var express = require('express');
var bodyParser = require('body-parser');
var app = express();
var morgan = require('morgan');
// configure app
app.use(morgan('dev')); // log requests to the console
// configure body parser
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
var port = process.env.PORT || 8080; // set our port
var mongoose = require('mongoose');
// mongoose.connect('mongodb://node:node#novus.modulusmongo.net:27017/Iganiq8o'); // connect to our database
mongoose.connect('mongodb://localhost:27017');
var Bear = require('./app/models/bear');
// create our router
var router = express.Router();
// middleware to use for all requests
router.use(function(req, res, next) {
// do logging
console.log('Something is happening.');
next();
});
// test route to make sure everything is working (accessed at GET http://localhost:8080/api)
router.get('/', function(req, res) {
res.json({ message: 'hooray! welcome to our api!' });
});
// on routes that end in /bears
// ----------------------------------------------------
router.route('/bears')
// create a bear (accessed at POST http://localhost:8080/bears)
.post(function(req, res) {
var bear = new Bear(); // create a new instance of the Bear model
bear.name = req.body.name; // set the bears name (comes from the request)
bear.email= req.body.email; // set the bears email(comes from the request)
bear.save(function(err) {
if (err)
res.send(err);
res.json({ message: 'Bear created!' });
});
})
// get all the bears (accessed at GET http://localhost:8080/api/bears)
.get(function(req, res) {
Bear.find(function(err, bears) {
if (err)
res.send(err);
res.json(bears);
});
});
// on routes that end in /bears/:bear_id
// ----------------------------------------------------
router.route('/bears/:bear_id')
// get the bear with that id
.get(function(req, res) {
Bear.findById(req.params.bear_id, function(err, bear) {
if (err)
res.send(err);
res.json(bear);
});
})
// update the bear with this id
.put(function(req, res) {
Bear.findById(req.params.bear_id, function(err, bear) {
if (err)
res.send(err);
bear.name = req.body.name;
bear.save(function(err) {
if (err)
res.send(err);
res.json({ message: 'Bear updated!' });
});
});
})
// delete the bear with this id
.delete(function(req, res) {
Bear.remove({
_id: req.params.bear_id
}, function(err, bear) {
if (err)
res.send(err);
res.json({ message: 'Successfully deleted' });
});
});
// REGISTER OUR ROUTES -------------------------------
app.use('/api', router);
// START THE SERVER
// =============================================================================
app.listen(port);
console.log('Magic happens on port ' + port);
The Model is given below:-
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var BearSchema = new Schema({
name: String,
email: String
});
module.exports = mongoose.model('Bear', BearSchema);
I am trying it to save the name and the email in the mongodb database but only _id is created instead of name, email.
Here is the result:-
[
{
"_id": "567f1f92db24304013000001",
"__v": 0
},
{
"_id": "567f2765db24304013000002",
"__v": 0
}
]
Can anybody tell me why the data are not getting saved in the database.
Please kindly help.
Thanks in Advance.

I think your POST request is not good, so I made this simple script to check it out:
var XHR = (function() {
var _xhr = (function() {
try {
return new(this.XMLHttpRequest || ActiveXObject)('MSXML2.XMLHTTP.3.0');
} catch (e) {}
})();
return function(method, url, params, callback) {
_xhr.onreadystatechange = function() {
if (_xhr.readyState == 4) {
var _response;
try {
_response = JSON.parse(_xhr.response);
} catch (e) {
_response = _xhr.responseText;
}
if (_xhr.status != 200) {
// catch an error
console.error('error', response);
} else {
if (callback) {
callback(_response);
} else {
// deal with it
}
}
}
}
if (!params) {
params = JSON.stringify({});
} else {
params = JSON.stringify(params);
}
_xhr.open(method, url, true);
// just json in this case
_xhr.setRequestHeader("Content-type", "application/json;charset=UTF-8");
_xhr.send(params);
};
})();
fire it up in browser's console, like this
XHR('POST','api/bears', { name:'yogi', email:'yogi#bears.com'}, function(){ console.log(arguments) });
and your record will be saved.
{ "_id" : ObjectId("567e875d068748ee5effb6e0"), "email" : "yogi#bears.com" "name" : "yogi", "__v" : 0 }
Long story short - your code is okay, your POST is not.
