            </div>

        </fieldset>
    </form>

</div>

controller/user.js

'use strict';

angular.module('clientApp')
  .controller('UserAddCtrl', function ($scope, Restangular, $location) {

     $scope.saveUser = function() {
         $scope.newUser = {};

         var restVar = Restangular.all('user');

         restVar.post($scope.newUser).then(function() {
             $location.path('/users');
             console.log('Success');
         }, function(response) {
             console.log('Error with status code', response.status);
         }); 
     };

 });

each time i execute the about codes, i get 400(bad request)... what im i doing wrong?

please note that im using mongodb and my db name is isdbmeanapp and my collection name is user, hence my server url is http://127.0.0.1:3000/user

In Restangular posts should be done to collections not elements.

In your case POST should be made like this;

$scope.newUser = {email :"", password: "", etc: ""};

Then make POST request like;

Restangular.all('user').post("users", $scope.newUser);

when i try the ur suggestion , this is what i get .... XMLHttpRequest cannot load 127.0.0.1:3000/…. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'localhost:9000' is therefore not allowed access. The response had HTTP status code 400.

In that case you should use CORS, more info is found here: html5rocks.com/en/tutorials/cors

on my server side here is how i handled CORS in my index.js file // CORS Support app.use(function(req, res, next) { res.header('Access-Control-Allow-Origin', '*'); res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE'); res.header('Access-Control-Allow-Headers', 'Content-Type'); next(); }); and even with that, i still have the above XMLHttpRequest error
