Question

我创建了一个资源对象：

factory('TextResource', 
    function($resource) {
        return $resource(adminBaseUrl+'/texts/:type', {}, {
            create: {method: 'POST', params: {type:'create'}, headers: {'Content-Type':'application/x-www-form-urlencoded'}},
            update: {method: 'POST', params: {type:'update'}, headers: {'Content-Type':'application/x-www-form-urlencoded'}},
            query: {method: 'GET', params: {type: 'list'}},
            remove: {method: 'POST', params: {type: 'remove'}, headers: {'Content-Type':'application/x-www-form-urlencoded'}},
            getText: {method: 'GET', params: {type: 'get', id:'@id'}}
        });
    }
)

我的控制器是：

controller('EditText', ['$scope', '$location', '$routeParams', 'TextResource', 'HttpStatusMessage',
    function($scope, $location, $routeParams, TextResource, HttpStatusMessage) {
        $scope.alerts = [];
        $scope.languages = [];

        TextResource.getText(
            {id: $routeParams.id},
            function(data) {
                $scope.languages = data.result;
            },
            function(error) {
                var httpError = new HttpStatusMessage(error.status);
                $scope.alerts.push({type:'error', msg:httpError.msg});
            });

        $scope.closeAlert = function(index) {
            $scope.alerts.splice(index, 1);
        }

        $scope.submit = function() {
            TextResource.update(
                $scope.languages,
                function(data) {
                    if( data.type == 'success' ) {
                        $location.path('texts');
                    } else {
                        $scope.alerts.push({type:data.type, msg:data.message});
                    }
                },
                function(error) {
                    var httpError = new HttpStatusMessage(error.status);
                    $scope.alerts.push({type:'error', msg:httpError.msg});
                });
        }

        $scope.cancel = function() {
            $location.path('texts');
        }
    }
])

我从TextResource.getText请求获得的响应是：

{"result":[{"id":"3","value":"This is my first text<br>","key":"my_first_text","language_id":"1","name":"English"},{"id":"3","value":"Ceci est mon premier texte","key":"my_first_text","language_id":"3","name":"French"}],"num_rows":2}

现在，当我点击提交时，它会显示错误：

Error: a.push is not a function

响应对象包含2个键结果，num_rows结果是一个数组。我没有在资源对象中使用isArray参数的原因是万一在服务器中发生任何错误，如会话超时，访问不允许等等。服务器返回一个对象包含错误消息。

通过修改更新功能解决问题，如：

$scope.submit = function() {
            TextResource.update(
                {'language':$scope.languages},
                function(data) {
                    if( data.type == 'success' ) {
                        $location.path('texts');
                    } else {
                        $scope.alerts.push({type:data.type, msg:data.message});
                    }
                },
                function(error) {
                    var httpError = new HttpStatusMessage(error.status);
                    $scope.alerts.push({type:'error', msg:httpError.msg});
                });
        }

我在更新中直接发布了一个抛出错误的数组。因此封装在另一个密钥中解决了这个问题。

Angularjs资源对象a.push不是一个函数
