Question

我有一些独特的角度火力设置，其中任务的路径是任务的周和日。

//for example this references a day collection that has tasks as children
var ref = new Firebase("https://talllly.firebaseio.com/tasks/" + $scope.currentWeek + '/' + day.$id);

$scope.currentWeek and day.$id are timestamps.

我的问题是我似乎无法访问该子任务以便能够删除它。如何访问各个任务以便删除它们？

这是视图

<section class="col user-tasks" user-color color="{{profile.name}}">
    <form ng-submit="addTask(task, user); task = null;">
      <input placeholder="What are you working on today?" ng-model="task"/>
    </form>
    <ul class="tasks-list">
      <li ng-repeat="day in week | reverseArray">
        <span ng-show="day">{{getDisplayDate(day.$id) | date:'EEEE, MMMM d'}}</span>
        <ul>
          <li ng-repeat="(key, task) in day | orderBy:'doneTime' | reverse" ng-show="task.addedBy === profile.name">
              <div class="row input-container">
                <div class="small-1 columns">
                  <input type="checkbox" ng-model="task.complete" ng-change="change(task, day)">
                </div>
                <div class="small-10 columns">
                  <input type="text" ng-model="task.text" ng-change="update(task)">
                </div>
                <div class="small-1 columns">
                  <span ng-click="delete(day, task)">x</span>
                </div>
            </div>
          </li>
        </ul>
      </li>
    </ul>
  </section>

另外，在相关的说明中但是如果有什么。$ id是对象的第一个值，我如何访问任务的-JXYiowyf-UerL3NeDm_级别？

编辑，更新以显示我正在获取任务的位置：

var populateTasks = function(date){
   var tasks = "https://talllly.firebaseio.com/tasks/" + getWeekStart(date);
   $scope.ref = new Firebase(tasks);
   var sync = $firebase($scope.ref);
   $scope.week = sync.$asArray();
 };

更新：我能够通过逐个重新创建功能来实现它。我仍然不完全确定发生了什么，但我的删除功能现在看起来像这样：

$scope.deleteTask = function(key, task, day){
  var sync = new Firebase(FBURL + '/tasks/' + $scope.currentWeek + '/' + day.$id);
  var deleteList = $firebase(sync);
  deleteList.$remove(key)
  .then();
};

我无法在angularfire中删除对特定任务的引用？
