AngularJS updating scope data of another controller

Question

I have an AngularJS webapp where upon logging out I am redirected to the login page. I wanted certain fields in the login page to be hidden based on some data passed back from the logout service in the backend.

Is there a way to do this ? I just need to update a variable in the login controller js but I am not sure how to do that from the logout controller js ?

Please help completely new to AngularJS!

You need to use the "value" option in your app

angular.module('yourAppName')
     .value('Config', null);

then you need to inject it in your controllers to make them communicate each others

.controller('controllerLogout', function(Config){
//do something that update Config
}

.controller('MainController' function(Config){
      //use Config here to bind it in a ng-show in HTML controlled by 
      //coontroller itself
}
