不能從工廠共享對象

Question

我想通過控制器共享一個對象數組posts.shoppingCart。 MainCtrl 這個表達式的作品$scope.cart = posts.shoppingCart;但是AuthCtrl沒有。我的虛擬數據顯示沒有問題。

var app = angular.module('test', ['ui.router']); 

app.config(['$stateProvider', '$urlRouterProvider', 
    function($stateProvider, $urlRouterProvider) { 

     $stateProvider.state('home', { 
      url : '/home', 
      templateUrl : '/home.html', 
      controller : 'MainCtrl', 
      resolve : { 
       postPromise : ['posts', 
        function(posts) { 
         return posts.getAll(); 
        }] 

      } 
     }).state('login', { 
      url : '/login', 
      templateUrl : '/login.html', 
      controller : 'AuthCtrl', 
      onEnter : ['$state', 'auth', 
       function($state, auth) { 
        if (auth.isLoggedIn()) { 
         $state.go('home'); 
        } 
       }] 

     }).state('register', { 
      url : '/register', 
      templateUrl : '/register.html', 
      controller : 'AuthCtrl', 
      resolve : { 
       postPromise : ['posts', 
        function(posts) { 
         return posts.getShoppingCart(); 
        }] 

      }, 
      onEnter : ['$state', 'auth', 
       function($state, auth) { 
        if (!auth.isLoggedIn()) { 
         $state.go('login'); 
        } 
       }] 

     }); 

     $urlRouterProvider.otherwise('login'); 
    }]); 


app.factory('posts', ['$http', 'auth', 
    function($http, auth) { 
     var o = { 
      posts : [], 
      shoppingCart : [] 
     }; 

     o.getAll = function() { 
      return $http.get('/catalog').success(function(data) { 
       angular.copy(data, o.posts); 
      }); 
     }; 

     o.getShoppingCart = function() { 
      return o.shoppingCart; 
     }; 

     return o; 
    }]); 



app.controller('MainCtrl', ['$scope', 'posts','auth', 
    function($scope, posts, auth) { 

     $scope.posts = posts.posts; 
     $scope.isLoggedIn = auth.isLoggedIn; 
     //setting title to blank here to prevent empty posts 

     $scope.sum = 0; 
     if ($scope.sum === 0) { 
      $scope.isDisabled = true; 
     } 

     $scope.cart = posts.shoppingCart; 
     var sum; 
     $scope.addPost = function(post) { 
      console.log(post); 
      $scope.cart.push({title: post.title, cost: post.cost}); 
      var sum = parseInt($scope.sum,10) + parseInt(post.cost, 10); 

      $scope.sum = sum; 
      $scope.isDisabled = false; 
     }; 
    }]); 

app.controller('AuthCtrl', ['$scope', '$state', 'posts', 'auth', 
    function($scope, posts, $state, auth) { 
     $scope.user = {}; 
     $scope.isLoggedIn = auth.isLoggedIn; 
     $scope.cart = [ 
      {title:'Jani',cost:'Norway'}, 
      {title:'Hege',cost:'Sweden'}, 
      {title:'Kai',cost:'Denmark'} 
     ];//posts.shoppingCart; 

     $scope.register = function() { 
      console.log($scope.user); 
      auth.register($scope.user).error(function(error) { 
       $scope.error = error; 
      }).then(function() { 
       $state.go('home'); 
      }); 
     }; 

     $scope.logIn = function() { 

      auth.logIn($scope.user).error(function(error) { 
       $scope.error = error; 
      }).then(function() { 
       $state.go('home'); 
      }); 
     }; 
    }]);

['$scope', '$state', 'posts', 'auth', 
function($scope, posts, $state, auth) { 

$狀態和崗位混合起來......
