擴展AngularJS $資源映射到Rails的REST風格的路線（特別是$保存創建和更新）

Question

我想映射默認AngularJS $資源行動：

'get': {method:'GET'} 
    'save': {method:'POST'} 
    'query': {method:'GET', isArray:true} 
    'remove': {method:'DELETE'} 
    'delete': {method:'DELETE'} 

這些5個Rails的REST風格的路線：

'show': {method:'GET'}     -> get 
    'create': {method:'POST'}    -> save 
    'update': {method:'PUT'}     -> save 
    'index': {method:'GET', isArray:true} -> query 
    'delete': {method:'DELETE'}    -> remove or delete 

除了save之外，一切都映射得很好。它適用於create作爲POST請求。但我想，當我保存有一個id != null

# This factory needs a smarter $save() method 
myServices.factory 'Message', ['$resource', ($resource) -> 
    Message = $resource "api/users/:user_id/messages/:id", 
     user_id: '@user_id' 
     id: '@id' 
    , 
     # update should not be needed 
     update: 
      method: 'PUT' 

    Message 
] 


myApp.controller "UsersShowCtrl", ["$scope", "$routeParams", "User", "Message", ($scope, $routeParams, User, Message) -> 
    $scope.user = User.get({id: $routeParams.user_id}) 
    $scope.myMessage = new Message {user_id: $routeParams.user_id} 

    $scope.submitMyMessage = -> 
     # This should just be: 
     # $scope.myMessage.$save() 
     # rather than: 
     unless $scope.myMessage.id? 
      $scope.myMessage.$save() 
     else 
      $scope.myMessage.$update() 

] 

我最終會想修改提交PARAMS也讓我可以將它們命名空間中的資源將其更改爲一個PUT請求默認軌嵌套參數即params[:message]而不是直接將它們附加到根params字符串，但首先我需要知道如何最好地修改$資源。

關閉我的頭頂，這個save（）方法怎麼樣？

myServices.factory 'Message', ['$resource', ($resource) -> 
    Message = $resource "api/users/:user_id/messages/:id", 
     user_id: '@user_id' 
     id: '@id' 
    , 
     # update should not be needed 
     update: 
      method: 'PUT' 

    Message::save = -> 
     if @id? 
      @update() 
     else 
      @create() 

    Message 
]
