在正确排序的情况下从Firebase中检索数据 [英] Retrieving data from firebase while sorting it correctly

问题描述

在我的firebase数据库中有这样的结构

I have this structure in my firebase database

"metadata" : {
    "2017" : {
      "Februari" : {
        "-Kc3BF0V1iLgtnI65LuR" : {
          "date" : "2017-02-03T13:36:38.311Z",
          "price" : 90
        },
        "-Kc3BF0V1xxfrtnI65OlS" : {
          "date" : "2017-02-03T13:36:38.311Z",
          "price" : 90
        }
      },
      "Januari" : {
        "-Kc3E5bpxpo3RpSHH3fn" : {
          "date" : "2017-01-11T13:50:12.264Z",
          "price" : 45
        }
      }
    }
  }

我试图在我的应用程序中实现的是显示一个像这样的列表

What I am trying to achieve in my app is to show a list like this

> Januari
>   - 45 (=price)
> 
> Februari
>   - 90 ()
>   - 240

事情是我可以显示月份，但我无法联系到孩子因为Firebase创建的唯一ID。

The thing is I am able to show the months, but I can't reach the children because of the unique ID created by firebase.

这是我从firebase返回的对象

This is the object I am getting back from firebase

e{
    $$conf: Object
    $id: "2017"
    $priority: null
    Februari: Object
        -Kc3BF0V1iLgtnI65LuR: Object
        date: "2017-02-03T13:36:38.311Z"
        price: 90
    Januari: Object
        -Kc3E5bpxpo3RpSHH3fn: Object
        date: "2017-01-11T13:50:12.264Z"
        price: 45
}

我会如何处理这个问题？ p>

How would I approach this?

推荐答案

您是否正在尝试使用ng-repeat？这样的工作会对你有用：

Are you trying to use an ng-repeat? Would something like this work for you:

<div ng-repeat="(name, month) in months">
    {{ name }}
    <div ng-repeat="entry in month">
        {{ entry.price }}
    </div>
</div>

其中months是 database.ref（） metaData'）。child（'2017'）;
