HTTP Post not connecting with angular - angularjs

Question

I'm new to the stack and am building a test page to sort out my understanding before building my actual project. Right now, I'm just trying to take user input, save it to a database, and print it. The data should be saved in a basic Mongoose model, test. While all of the routes are open, instead of printing what the user entered it prints something in the following format:
{"_id":"55c3925b48b9dba0d896be40","__v":0}
I suspect it has something to do with the second line of this snippet from index.js:
router.post('/survey', function(req, res, next) {
var test = new Test(req.body);
test.save(function(err,test) {
if(err) {
return next(err);
}
res.json(test);
});
});
module.exports = router;
Relevent code:
All of index.js:
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
//set up routes
var mongoose = require('mongoose');
var Test = mongoose.model('Test');
router.get('/survey', function(req, res, next) {
Test.find(function(err, tests) {
if(err) {
return next(err);
}
res.json(tests);
});
});
router.post('/survey', function(req, res, next) {
var test = new Test(req.body);
test.save(function(err,test) {
if(err) {
return next(err);
}
res.json(test);
});
});
module.exports = router;
Tests.js (model):
var mongoose = require('mongoose');
var TestSchema = new mongoose.Schema({
'name': String,
});
module.exports = mongoose.model('Test', TestSchema);
Relevant bits of angular code:
routerApp.factory('tests', ['$http', function($http){
var o = {
tests: []
};
o.getAll = function() {
return $http.get('/survey').success(function(data){
console.log('get all sees data as:' + data);
angular.copy(data, o.tests);
});
};
o.create = function(test) {
console.log('create sees test as' + test);
return $http.post('/survey', test).success(function(data){
o.tests.push(data);
console.log('Data:' + data);
});
};
return o;
}]);
routerApp.controller('FormCtrl', ['$scope', 'tests',
function($scope, tests){
$scope.test = tests.tests;
$scope.addTest = function(){
if(!$scope.text || $scope.text === '') { return; }
tests.create({
name: $scope.text
});
$scope.text = '';
};
}
]);
I suspect this is a matter of not understanding what kind of object req is, but I'm not entirely positive. How would I go about making this code save data in the format described in the mongoose model?

Answer 1

If you call .toObject() on the document object (res.json(test.toObject())), you should get a plain object back containing the data in that document.

Answer 2

Try to console.log(req.body). If it's empty, then try adding app.use(bodyParser.json()) somewhere before your routes are defined (and be sure to install it with npm and require it first).
When you POST some sort of JSON, it isn't available in req.body by default. You need bodyParser to parse the incoming data and make it available in req.body. See https://medium.com/#adamzerner/how-bodyparser-works-247897a93b90 for more info.
