Javascript 如何在整个JSON树中更新firebase数据库上的节点？

我的web应用程序基于足球联赛。我有一个Javascript对象数组。每个玩家都是阵列中的一个对象：

 $scope.players = [
   {name : "Yasin 'YB' Amusan", Team : "Industry", price: 8000000, position: 'forward', image: src='http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png'},
   {name : "Hassan 'Hasi' Akinyera", Team : "Industry", price: 5000000, position: 'defender', image: src='http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png'},
   {name : "Femi 'Fabio' Awoniyi", Team : "Industry", price: 9000000, position: 'defender',image: src='http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png'},
   {name : "Deji 'Dej' Awoniyi", Team : "Industry", price: 7000000, position: 'forward',image: src='http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png'},
   {name : "Koye 'K10' Kekere-Ekun", Team : "Industry", price: 9000000, position:'midfielder', image: src='http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png'},
   {name : "Teni 'Teezee' Zacchaeus", Team : "Industry", price: 6000000, position:'hybrid', image: src='http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png'},
   {name : "Bolaji 'Boj' Odojukan", Team : "Industry", price: 7000000, position:'forward', image: src='http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png'}
 ];

然而，当玩家数量增加到47人左右时，我决定使用firebase作为后端。因此，我制作了一个玩家的JSON文件，并将其导入firebase数据库：

 {
"players" : [
   {"name" : "Yasin 'YB' Amusan", 
    "Team" : "Industry",
    "price": 8000000, 
    "position": "forward", 
   "image":"http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png", 
    "goals": 0, 
    "assists" : 0, 
    "Y" : 0, 
    "R" : 0},
   {"name" : "Hassan 'Hasi' Akinyera",
    "Team" : "Industry", 
    "price": 5000000, 
    "position": "defender",
    "image":"http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png",
    "goals": 0, 
    "assists" : 0,
    "Y" : 0,
    "R" : 0},
   {"name" : "Femi 'Fabio' Awoniyi",
    "Team" : "Industry",
    "price": 9000000,
    "position": "defender",
    "image":"http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png",
    "goals": 0, 
    "assists" : 0, 
    "Y" : 0, 
    "R" : 0},
   {"name" : "Deji 'Dej' Awoniyi",
    "Team" : "Industry",
    "price": 7000000,
    "position": "forward",
     "image":"http://res.cloudinary.com/deji/image/upload/v1489787662/blank_photo_mqvivv.png",
    "goals": 0, 
    "assists" : 0, 
    "Y" : 0, 
    "R" : 0}
  ....etc
   ]
   }

将列出玩家，供用户使用：

var ref = firebase.database().ref().child('players');
 $scope.players = $firebaseArray(ref);
  console.log ($scope.players); 

当每个用户挑选他们想要的玩家时，它会被发布到名为“gameweek 1”的“用户”节点下的子节点，并根据每个玩家的性能/统计数据分配相应的分数

我的问题

我的问题是如何更新数据库中“玩家”节点中的玩家统计信息，使其在“用户”节点中每个用户选择下的“游戏周”子节点中更新。

由于要同时更新多个路径的路径，您正在查找firebase.database（）.ref（）.update（），可在此处找到（）@user7814783我想更像是在firebase控制台中手动更新它。这是不可能的吗？没有手动是不可能的，你必须随时随地改变它，否则你可以考虑使用云函数来触发一个函数，当数据库中的一个节点被改变并在你想要的节点中应用更改时。
