错误：关键$$ hashKey不能以“$”开头（AngularJS） [英] Error: key $$hashKey must not start with '$' (AngularJS)

问题描述

尝试添加一些我的收藏时，我得到了以下错误：

Attempting to add something to my collection when I got the following error:

Exception while invoking method 'submit' Error: key $$hashKey must not start with '$'

每个餐对象：

$scope.meal = {
  items:[],
  createdBy:null
};

下面是我提出我的控制器内的功能：

Here is my submit function inside my controller :

$scope.submit = function() {
  var currentUserId = Meteor.userId();

  if(currentUserId!=null) {
    if($scope.checkValidity()==false) {
      alert("Need to fill out valid calories and/or items!");
    }
    else {
      $scope.meal.createdBy = currentUserId;
      Meteor.call("submit", $scope.meal);
      alert("has just been submitted");
    }
  }
  else {
    alert("You must sign in first!");
  }
}

我已经盘问我提交功能，无数次，但我似乎无法找到一个错误。我看对谷歌以及的这个错误，它似乎是它的一点点在我的头上，特别是因为我还是一个初学者角。在此期间，我会试图找到更多的信息。

I've cross examined my submit function numerous times but I can't seem to find an error. I've looked on google as well of this error and it seems like its a little over my head especially because I'm still a Angular beginner. In the meantime, I'll attempt to find more information.

好像他们从固定的意见呢？然而，同样的问题已经up..Check出来。

Seems like they fixed it from the comments? Yet the same problem has come up..Check it out.

推荐答案

为对象添加到吃饭的项目，请尝试使用：

to add a object to the items of the meal, try using:

  $scope.meal.items.push(angular.copy($scope.newItem));

当你骂

 Meteor.call("submit", angular.copy($scope.meal));

这是因为角度使用引用跟踪对象

this is because angular uses a reference to track the object
