AngularJS Question

Restangular get response errors

I have a simple auth factory in angular with the following codes

.factory 'User',($window,$rootScope,Restangular)->
{
auth: (username,password)->
Restangular.all 'auth/login/'
.post {username:username,password:password}
.then (response)->
return response
,(response) ->
return response
.....


and i am calling that from my controller using

$scope.login = ()->
$scope.running = 1
console.log User.auth $scope.username,$scope.password
$scope.running = 0
return


The problem is that i need to show the errors on login if any and set them in
controller
but
restangular
being async, i am not sure how to do to same. As you can see from the first code segment that i tried to return the values but even they don't seem to work.

How can i get the reponse codes from the server in scope using Restangular

Answer

You should return the restangular call, which is a promise. Then on the callbacks you can do something with the errors:

auth: (username,password)->
    return Restangular.all 'auth/login/'
    .post {username:username,password:password}

controller:

$scope.login = ()->
    $scope.running = 1
    User.auth( $scope.username,$scope.password)
    .then (response)->
        // success
    ,(response)->
        // fail
    .finally (response)->
        $scope.running = 0
