在RABL中删除子根节点 [英] Removing child root nodes in RABL

问题描述

我正在尝试使用RABL渲染一个非常简单的数据结构，但是我不知道如何正确删除子根节点.这是我的两个模板.

I'm trying to render a pretty simple data structure using RABL, but I can't figure out how to remove the child root nodes properly. Here are my two templates.

首先是集合索引模板.

collection @groups, :object_root => false

attributes :id, :name
child :files do
  extends 'groups/_file'
end

然后是文件部分模板.

object @file

attributes :id

这两个模板最终产生以下JSON:

Those two templates end up producing the following JSON:

[
   {
      "id":"4f57bf67f85544e620000001",
      "name":"Some Group",
      "files":[
         {
            "file":{
               "id":"4f5aa3fef855441009000007"
            }
         }
      ]
   }
]

我想找到一种方法来删除文件集合中的根文件"键.像这样:

I want to find a way to remove the root "file" key inside of the files collection. Something like:

[
   {
      "id":"4f57bf67f85544e620000001",
      "name":"Some Group",
      "files":[
         {
            "id":"4f5aa3fef855441009000007"
         }
      ]
   }
]

推荐答案

在最新版本的Rabl中，如果希望所有级别的include_root_json都为false，则必须设置此配置.

On latest versions of Rabl, you have to set this configuration if you want include_root_json to be false in all levels.

Rabl.configure do |config|
  config.include_json_root = false
  config.include_child_root = false
end
