sideMenu Example: Controller child-parent communication

Hello out there,

yesterday I started my first Ionic Project. Since I wanted a side-menu I chose the example project “sideMenu”.

There is one thing I don’t get. How do I access the scope of a parent controller? $scope.$parent is not giving me back the parents $scope.

In the example the code is as following:

app.js

 $stateProvider

  .state('app', {
    url: "/app",
    abstract: true,
    templateUrl: "templates/menu.html",
    controller: 'AppCtrl'
  })

  .state('app.search', {
    url: "/search",
    views: {
      'menuContent': {
        templateUrl: "templates/search.html"
      }
    }
  })

  .state('app.browse', {
    url: "/browse",
    views: {
      'menuContent': {
        templateUrl: "templates/browse.html"
      }
    }
  })
    .state('app.playlists', {
      url: "/playlists",
      views: {
        'menuContent': {
          templateUrl: "templates/playlists.html",
          controller: 'PlaylistsCtrl'
        }
      }
    })

  .state('app.single', {
    url: "/playlists/:playlistId",
    views: {
      'menuContent': {
        templateUrl: "templates/playlist.html",
        parent: 'app.playlists',
        controller: 'PlaylistCtrl'
      }
    }
  });

controller.js

controller('AppCtrl', function($scope, $ionicModal, $timeout) {
  // Form data for the login modal
  $scope.loginData = {};

  // Create the login modal that we will use later
  $ionicModal.fromTemplateUrl('templates/login.html', {
    scope: $scope
  }).then(function(modal) {
    $scope.modal = modal;
  });

  // Triggered in the login modal to close it
  $scope.closeLogin = function() {
    $scope.modal.hide();
  };

  // Open the login modal
  $scope.login = function() {
    $scope.modal.show();
  };

  // Perform the login action when the user submits the login form
  $scope.doLogin = function() {
    console.log('Doing login', $scope.loginData);

    // Simulate a login delay. Remove this and replace with your login
    // code if using a login system
    $timeout(function() {
      $scope.closeLogin();
    }, 1000);
  };
})

.controller('PlaylistsCtrl', function($scope) {
  $scope.playlists = [
    { title: 'Reggae', id: 1 },
    { title: 'Chill', id: 2 },
    { title: 'Dubstep', id: 3 },
    { title: 'Indie', id: 4 },
    { title: 'Rap', id: 5 },
    { title: 'Cowbell', id: 6 }
  ];
})

.controller('PlaylistCtrl', function($scope, $stateParams) {
  console.log($scope.$parent.playlists);
});

How can I access the playlists in ‘PlaylistsCtrl’ from my controller ‘PlaylistCtrl’? Is it possible at all?

Looking forward to your answers!

I am not sure why you specify 2 controllers both called PlaylistsCtrl? This can’t work! Normally you would have the data in a service and call a function of that service inside your controller.

Please look at the two controllers, the one is a plural of playlists. So there is no chance of controller inheritance?
