AngularJS资源

Question

我正在学习AngularJS。 我的服务：

services.factory('Model', ['$resource', 
function ($resource) { 
    return $resource('model/:id', {}, {}); 
} 
]); 

services.factory('Department', ['$resource', 
function ($resource) { 
    return $resource('department/:id', {}, {}); 
} 
]); 

services.factory('Price', ['$resource', 
function ($resource) { 
    return $resource('price/:id', {}, {}); 
} 
]); 

我的控制器：

controllers.controller('SafeNewCtrl', ['$scope', '$location', 'Safe', 'Model', 'Department', 'Price', 
function ($scope, $location, Safe, Model, Department, Price) { 
    $scope.models = Model.query(); 
    $scope.departments =Department.query(); 
    $scope.prices = Price.query(); 

    // It doesn't work. console.log($scope.models[0] 'and other') = undefined. 
    $scope.safe = {model: $scope.models[0], department: $scope.departments[0], price: $scope.prices[0]}; 

    $scope.save = function() { 
     var safe = new Safe($scope.safe); 
     safe.$save(function() { 
      $location.path('list/f'); 
     }) 
    } 
} 
]); 

我有资源阵列每次查询后（）。 如何获得正常的JSON作为数组和数组的第一个对象设置为$ scope.safe？

controllers.controller('SafeNewCtrl', ['$scope', '$location', 'Safe', 'Model', 'Department', 'Price', '$q', 
function ($scope, $location, Safe, Model, Department, Price, $q) { 
    $scope.models = Model.query(); 
    $scope.departments =Department.query(); 
    $scope.prices = Price.query(); 

    $q.all([$scope.models.$promise, $scope.departments.$promise, $scope.prices.$promise]).then(function(){ 
     $scope.safe = {model: $scope.models[0], department: $scope.departments[0], price: $scope.prices[0]}; 
     console.log($scope.models[0]); 
    }) 



    $scope.save = function() { 
     var safe = new Safe($scope.safe); 
     safe.$save(function() { 
      $location.path('list/f'); 
     }) 
    } 
} 
]);
