Question

我在Angular js中有一个Reactivemongo项目，我正在尝试从集合中删除文档。我写了我的Scala控制器：

def delete = Action.async {
collection.remove(BSONDocument("_id" -> _id)).map(_ => Ok(s"User Deleted")).recover { case _ => InternalServerError }}

我的Angular控制器如下：

controller("GuestCtrl", ["$scope", "$http", function($scope, $http){

      $http.get("/guest/all").success(function(res){
      console.log(res);
      $scope.guests = res;
       });


       $scope.deleteGuest = function(guest){
       console.log(guest);
       $http.post("/guest/delete", guest).success(function(result){

       });
       };




       $scope.registerGuest = function(newguest){
        console.log(newguest);
        $http.post("/guest/create", newguest).success(function(result){
        $scope.newguest = result;
        });
        };


        }]);

我的角度html页面是：

<div class= "col-md-5">
    <ul class="guests">
        <li ng-repeat="guest in guests ">

        <h1>{{guest.name}}</h1>

        <p>{{guest.address}}</p>

        <input type="submit" value="Delete" ng-click="deleteGuest(guest)">
            <input type="submit" value="Update" ng-click="updateGuest(guest)">
        </li>
    </ul>

</div>

如果有人知道如何进行更新和删除，请帮我解决！我在Angular控制器中写了一个删除函数，但它没有用。

我实际上解决了这个问题......将我的角度控制器更新为

 $scope.deleteGuest = function(guest){
       console.log(guest);
       $http.post("/guest/delete", {guest: guest}).success(function(result){

       });
       };

和我的Scala控制器

def delete = Action.async(parse.json){ request =>
val delGuest = ( request.body \ "guest").as[Guest]
 println (delGuest)

guestCollection.remove(Json.obj("_id" -> delGuest._id)).map(_ => Ok).recover { case _ => InternalServerError }}
