AngularJS Reload controller variable

Question

i would reload variable in controller that use for navbar.

I have controller for each view. I use a controller, loginCtrl, to login after i logged i would reload the var set in "rootController".

I use a variable for ng-if to switch button login and logout in navbar, but this variable (in rootController) is getting to call a factory function.

The problem are that variable one time is set don't change when i change value of factory. The solution is reload only rootController to reset var, search to internet i found $route.reload(). I've create a function in rootController and i use it so:

 $rootScope.reload = function(){ $timeout(function () {
                                           $route.reload();
                                           }, 0);
                                };

but when i call in other controller the app loads infinity.

How resolve it?

EDIT:

angular.module('appModule',[])
.controller('AppCtrl',function ($scope,$rootScope,UserLogged){
       $scope.isLogged = UserLogged.isLogged();
       $scope.user = UserLogged.get();
 });
.config(...) // To configure route, one route have loginCtrl as controller

.controller('loginCtrl',function($scope,$http,UserLogged){
    $http.get(..).sucess(function(data){UserLogged.set(data)}) 
                         // call a WS to setup the factory UserLogged    
)

.factory('UserLogged',function(){
var userLogged
var isLogged
 // set and get method
}

All work fine but when i update the isLogged var in factory the app don't update $scope.isLogged in AppCtrl. The solution are reload AppCtrl to recall UserLogged.get() and reset $scope.isLogged with the new value.

SOLVED:

@ rtvalluri Thanks

// App control
$scope.$on('loginLogout',function(){
     $scope.isLogged = UserLogged.isLogged();
     $scope.userLogged = UserLogged.get();
});

// loginCtrl
$http.get(..).sucess(function(data){
                                    UserLogged.set(data);
                                    $scope.$emit('loginLogout');
                                   })

Can you post the code form loginCtrl use to set the variable in the factory, post he complete factory code and post how the rootCtrl uses the variable from factory? — GPicazo

So emitting the event solved your issue finally ;) Cheers .. :) @Fabrizio — rtvalluri

You can try emitting two events for login and logout, with which you can update variable in rootController without refreshing it

In your navbar

<button ng-if="!isLoggedIn">Login</button>
<button ng-if="isLoggedIn">Logout</button>

If mainController is the rootController and login and logout are the two different functions in two different controllers,

then keep listening in rootController using:

$scope.$on('login',function(event,data){
  //assume 'isLoggedIn' is the boolean value
  $scope.isLoggedIn = data;
});

$scope.$on('logout',function(event,data){
  $scope.isLoggedIn = data;
});

Try emitting 'login' event from Login Controller

//on successful login, trigger below event
$scope.$emit('login',true);

and in Logout Controller

//on successful logout, trigger below event
$scope.$emit('logout',false);

Note: Above approach works only if mainController is the parent controller for other controllers, otherwise try emitting events on $rootScope instead of $scope
