AngularJS 使用唯一 ID 链接多 JSON

Question

我在 mongoDB 中有 2 个集合：

消息：

{
        "_id" : ObjectId("542e65368a1cec1227ae2bac"),
        "message" : "hello"
 }

分类：

{
        "_id" : ObjectId("542e65368a1cec1227ae2bac"),
        "result" : {
                "full" : "voyage",
                "others" : "voyage"
        }
}

我可以显示集合中的 ID 消息：

 "542e65368a1cec1227ae2bac, hello":

与：

{{image._id}}，{{image.message}}

来自我的 JSON：

{ "images" : 
   [ 
      { 
       "_id" : "542e65368a1cec1227ae2bac",
       "message" : "hello"
      } 
   ] 
}

但我还想显示“航程”。

感谢您的帮助

var app = angular.module('app', []);

app.controller('fCtrl', function($scope) {


  $scope.messages = {
    "images": [{
      "_id": "542e65368a1cec1227ae2bac",
      "message": "hello"
    }]
  }

  $scope.categories = [{
    "_id": "542e65368a1cec1227ae2bac",
    "result": {
      "full": "voyage",
      "others": "voyage"
    }
  }]


});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
  <div ng-controller="fCtrl">
    <div ng-repeat="message in messages.images">
      <p>{{message._id}} - {{message.message}}
        <p ng-repeat="cat in categories | filter: {'_id':message._id}">{{cat.result.others}}</p>
    </div>
  </div>
</div>
