mongoose saves an empty object

Question

I have a promblem with saving data to db, mongoose saves empty object without value. Using mean stack.

controller: for example i send some "hello message"

    $http({
            method: 'POST',
            url: '/api/message',
            headers: {'Content-Type': 'application/json'},
            data: JSON.stringify({msg: $scope.message})      
        }).

        success(function(response) {
            console.log("Success " + JSON.stringify(response));
        }).

        error(function(response) {
            console.log("Error " + JSON.stringify(response));
        });

server.js

    var bodyParser = require('body-parser');
    app.use(bodyParser.urlencoded({'extended':'true'}));
    app.use(bodyParser.json());
    app.use(bodyParser.json({type: 'application/vnd.api+json'}));

    var message = mongoose.model('Message', {
    message: String
    })

    app.post('/api/message', function(req,res) {
    var message = new Message(req.body);
    message.save(function(err) {
        if(err) throw err;

        console.log(message);
    })

    res.status(200).send();
    console.log(req.body);
    })

my "hello" message reaches the server, but mongoose saves an empty object

{msg: "hello"} // console.log(req.body);
{"_id":"584ee18f169f902b7046e991","__v":0} // console.log(message);

what im doing wrong??

Answer 1

You have a mismatch between your request body and the Message definition. req.body contains a msg property, but Message is expecting a message property.

I would swap the following line in your angular controller:

data: JSON.stringify({msg: $scope.message})    

To this:

data: JSON.stringify({message: $scope.message})

You could also update the Message model to have a property named msg instead of changing your angular code, if you'd prefer.
