AngularJS - Need some combination of $routeChangeStart and $locationChangeStart

Question

My problem is actually very similar to the one found here:

AngularJs - cancel route change event

In short, I\'m using $routeChangeStart and trying to change

Answer 1

Nice answer Marius, put me on the right track. I'm doing something like this for access control. This works however...

  var resolver = function(route, routeEvent) {
  return {
    load: function($q) {
      deferred = $q.defer();
      if (routeEvent!=3) { // eventually will be a list of routeEvents that the logged-in user is not allowed to visit read from a db table configured by admin
        deferred = $q.defer();
        deferred.resolve();
        return deferred.promise;
      } else { // fire $routeChangeError
        alert("You don't have permissions to access this.");
        deferred.reject(route);
        return deferred.promise;
      }
    }
  }
}

  var jsonRoutes = [

    {'route' : '/logout', 'templateUrl': 'partials/login.html',   'controller' : 'LoginCtrl', 'routeEvent' : 1 },
    {'route' : '/orders', 'templateUrl': 'partials/orders.html',   'controller': 'OrderListCtrl', 'routeEvent' : 2 },
    {'route' : '/products', 'templateUrl': 'partials/products.html',   'controller': 'ProductListCtrl', 'routeEvent' : 3 },

...

];


// somewhere on successful login code add in the dynamic routes

angular.forEach(jsonRoutes, function(r) {
                $route.routes[r.route] = {templateUrl: r.templateUrl, controller: r.controller, routeEvent: r.routeEvent, resolve: resolver(r.route, r.routeEvent)};
                  });


// got some static routes too which don't have access control - user has to login right?

  config(['$routeProvider', function($routeProvider) {


  $routeProvider.
    when('/error',  {templateUrl: 'partials/error.html',   controller : ErrorCtrl,  routeEvent : 1 }).
    when('/login',  {templateUrl: 'partials/login.html',   controller : LoginCtrl, routeEvent : 1 }).
    when('/home',  {templateUrl: 'partials/home.html',   controller : HomeCtrl, routeEvent : 1 }).
    when('/logout', {templateUrl: 'partials/login.html',   controller : LoginCtrl, routeEvent : 1 }).
    otherwise( {redirectTo: '/error'} );   

When the /orders route is clicked the promise is rejected (with a pop-up, could be modal dialog) and the route isn't followed.

Hope this helps someone.
