Express node.js with mongoose CRUD strange behavior. - node.js

Question

I'm starting my adventure with NodeJS. I've choose express web framework with mongoose database. As part of my front-end I'm using AngularJS.
First the front end, basic form args passing to /api/user.
$scope.form = {};
$scope.submitUser = function () {
console.log($scope.form);
$http.post('/api/user', $scope.form).
success(function(data) {})
.error(function(data) {});
};
$scope.form equals to:
Object {name: "foo", surname: "bar", email: "foobar#bar.foo"}
Then we got the back-end, where I start with default user schema:
var userSchema = new mongoose.Schema({
name : String,
surname : String,
email : String
});
var User = mongoose.model('User', userSchema);
And the api post handler:
app.post('/api/user', function (req, res) {
User.create({
name : req.name,
surname : req.surname,
done : false
}, function(err, user) {
if (err)
res.send(err);
res.json(user);
});
});
And the result of that instead of object is just id with __v:
__v: 0
_id: "536e218351b1182d0f000001"
PS. This one is magic, I have completly no idea why this is happening:
Those records above __v and _id, are not being save anywhere (show collections, and find() on each of those results in null). But when I run
User.find(function(err, users) {
if (err)
res.send(err)
res.json(users);
I get few records (previous tries of passing this form) with it's __v and _id.
Connection looks like this:
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:1/test');
Thanks for any tips, explanation to that. Sorry for my lack of knowledge but I really tried.
Have a nice day! ;)

Answer 1

Assuming that you send the json object in the body (payload) of POST from client, The server should access the value as req.body.name, not req.name
app.post('/api/user', function (req, res) {
User.create({
name : req.body.name,
surname : req.body.surname,
done : false
}, function(err, user) {
if (err)
res.send(err);
res.json(user);
});
});
Make sure you pass body-parser middleware to express:
var express = require('express')
var app = express()
app.use(express.bodyParser()); // for express 3.x
or for express 4.x
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
app.use(bodyParser()); // for express 4.x

In my case it does not work. Why?
I am getting the value from req.body.name
If I log it console.log(req.body.name); I get the value on my console.
POST:
{ name: 'typing any name', status: null }
typing any name
So the workflow between my frontend (angular.js), the form and the backend (node.js, express, mongoose) seems to work. Now I POST the value, but I get an empty object in my mongoDB.
{"_id":"543a50a974de6e2606bd8478","__v":0}
app.post('/api/offers', function (req, res){
var offer;
console.log("POST: ");
console.log(req.body);
console.log(req.body.name);
offer = new OfferModel({
name: req.body.name,
value: req.body.value,
title: req.body.title,
content: req.body.content,
});
offer.save(function (err) {
if (!err) {
return console.log("created offer" + req.body.name);
} else {
return console.log(err);
}
});
return res.send(offer);
});
And here is the model:
var offerSchema = mongoose.Schema({
offer : {
name : String,
value : String,
title : String,
content : String,
image : String,
start : String,
end : String,
targets : String,
beacons : String,
published : String
}
});
var OfferModel = mongoose.model('Offer', offerSchema);
