Devise Angular Authentication - ruby-on-rails

Question

I am trying to authenticate into devise via angular. On loading localhost, I see a POST 401 error. This issue seems to be with some devise setting, as my X-CSRF-TOKEN is being passed, but my POST requests aren't accepted.
I am able to register a user successfully, and immediately log in to that user (register also logs user in). I am then able to log out.
Here is the issue: I cannot log in to that user again.
My angular app is inside rails, so the two aren't disconnected.
What do I do? Here are relevant files:
app.js
var myApp = angular.module('myApp', ['templates','ui.router','ui.bootstrap', 'Devise']);
myApp.config([
'$httpProvider', function($httpProvider) {
return $httpProvider.defaults.headers.common['X-CSRF-Token'] = $('meta[name=csrf-token]').attr('content');
}
]);
myApp.config(function ($stateProvider, $urlRouterProvider, $locationProvider) {
/**
* Routes and States
*/
$stateProvider
.state('home', {
url: '/',
templateUrl: 'home.html',
controller: 'HomeCtrl'
})
.state('login', {
url: '/login',
templateUrl: 'login.html',
controller: 'AuthCtrl',
onEnter: ['$state', 'Auth', function($state, Auth) {
Auth.currentUser().then(function (){
$state.go('home');
})
}]
})
.state('register', {
url: '/register',
templateUrl: 'register.html',
controller: 'AuthCtrl',
onEnter: ['$state', 'Auth', function($state, Auth) {
Auth.currentUser().then(function (){
$state.go('home');
})
}]
});
// default fall back route
$urlRouterProvider.otherwise('/');
// enable HTML5 Mode for SEO
//$locationProvider.html5Mode(true);
});
myApp.run(function() {
return console.log('angular app running');
});
authCtrl.js
angular.module('myApp')
.controller('AuthCtrl', [
'$scope',
'$state',
'Auth',
function($scope, $state, Auth){
$scope.login = function() {
Auth.login($scope.user).then(function(){
$state.go('home');
});
};
$scope.register = function() {
Auth.register($scope.user).then(function(){
$state.go('home');
});
};
}]);
navCtrl.js
angular.module('myApp')
.controller('NavCtrl', [
'$scope',
'Auth',
function($scope, Auth){
$scope.signedIn = Auth.isAuthenticated;
$scope.logout = Auth.logout;
Auth.currentUser().then(function (user){
$scope.user = user;
});
$scope.$on('devise:new-registration', function (e, user){
$scope.user = user;
});
$scope.$on('devise:login', function (e, user){
$scope.user = user;
});
$scope.$on('devise:logout', function (e, user){
$scope.user = {};
});
}]);
applicaton_controller.rb
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
respond_to :json
def index
end
end
I have Devise gem installed, and using angular, angular-ui, angular-devise in Bowerfile

Answer 1

It looks like changing :exception to :null_session worked.. Why is this?
