角+ Rails的：角找不到控制器功能

Question

問題：我寫了一個角/ Rails應用程序，當我試圖從角控制器訪問Rails控制器的功能，我得到一個錯誤：Uncaught TypeError: tasks.moveOrder is not a function，但所有其他功能上該頁面可

tasks_controller.rb

def index 
    respond_with Task.all 
end 

def create 
    respond_with Task.create(task_params) 
end 

def destroy 
    task = Task.find(params[:id]) 
    task.destroy 

    respond_with task 
end 

def show 
    respond_with Task.find(params[:id]) 
end 

def moveOrder # This is the function that cannot be found 
    task = Task.find(task_id) 
    task.position = pos 

    respond_with task 
end 

def up_completion 
    task = Task.find(params[:id]) 
    task.increment!(:completion) 

    respond_with task 
end 

def down_completion 
    task = Task.find(params[:id]) 
    task.decrement!(:completion) 

    respond_with task 
end 

private 
def task_params 
    params.require(:task).permit(:title, :completion, :importance, :steps, :clicked, :position) 
end 

這些函數有路線和各功能是通過我的角度控制器稱爲：

MainCtrl.js

.controller('MainCtrl', [ 
'$scope', 
'tasks', 
function($scope, tasks){ 

    $scope.tasks = tasks.tasks; 
    $scope.items = ['one', 'two', 'three']; 

    $scope.addTask = function() { 
     var taskPosition = tasks.tasks.length + 1; 
     if(!$scope.title || $scope.title === '') { return; } 
     tasks.create({ // This call to the .rb file works! 
      title: $scope.title, 
      importance: $scope.importance, 
      completion: 0, 
      steps: $scope.steps, 
      clicked: false, 
      position: taskPosition // puts position as field in db (needs to be updated when dragged) 
     }); 
     $scope.title = ''; 
     $scope.importance = ''; 
     $scope.steps = ''; 
    }; 

    $scope.moveTask = function(start_pos, end_pos) { 
     $.get("http://localhost:3000/tasks.json") 
     .done(function(data) { 
       var task_id = data[start_pos].id; 
       tasks.moveOrder(task_id, end_pos) // This call to the .rb file fails! 
     }); 
    }; 

    ... 

app.js

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

    $stateProvider 

    .state('home', { 
     url: '/home', 
     templateUrl: 'home/_home.html', 
     controller: 'MainCtrl', 
      resolve: { 
       taskPromise: ['tasks', function(tasks){ 
        return tasks.getAll(); 
       }] 
      } 
    }) 

     .state('tasks', { 
      url: '/tasks/{id}', 
      templateUrl: 'tasks/_tasks.html', 
      controller: 'TasksCtrl' 
     }); 

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

是函數調用失敗，因爲我寫的東西不正確或者是有一些其他的問題，乾脆？

您應該檢查文檔$resource。提供了RESTful路由（因此create,get等將起作用），但您需要明確定義其他操作，您將映射到與控制器操作對應的路由。你會這樣做：

app.factory('Tasks', ['$resource', function($resource) { 
return $resource('/tasks/:id', null, 
    { 
    'moveOrder': { method:'POST', url: 'route_to_your_action' }, 
    'otherAction': { url: 'route_to_your_action' } 
    }); 
}]);
