使用类似的键加载和生成Yaml文件

Question

我有一个yaml文件文件有类似的键: -

sample_file.yml

line:
  title: line-name
  department: transcription

  input_formats:
    - input_format:
        name: company
        required: true
        valid_type: general
    - input_format:
        name: website
        required: false
        valid_type: url

生成new_file.yml后,键按字母顺序排序: -

new_file.yml

line: 
  department: transcription
  input_formats: 
    - 
      input_format: 
      name: company
      required: true
      valid_type: general
    - 
      input_format: 
      name: website
      required: false
      valid_type: url

  title: line-name

打开sample_file并生成new_file的代码如下: -

require 'yaml'
require 'ya2yaml'


@file = YAML::load(File.open("/Users/manish/Desktop/yaml/sample_file.yml"))
@new_file = File.new("/Users/manish/Desktop/yaml/new_file.yml", "w+") 
@new_file.syswrite(@file.ya2yaml(:hash_order => ['title','department','input_formats']))

我正在使用"ya2yaml"gem生成yaml文件.为了获得与sample_file.yml中相同的顺序,我在这里使用了hash_order @new_file.syswrite(@file.ya2yaml(:hash_order => ['title','department','input_formats'])),但它不起作用.我如何保留订单？

最后我得到了订购问题的解决方案.

:hash_order仅适用于顶级哈希.
所以只有当我从sample_file.yml中删除"line"键时它才有用.然后保留订单.: -

title: line-name
department: transcription

input_formats:
  - input_format:
      name: company
      required: true
      valid_type: general
  - input_format:
      name: website
      required: false
      valid_type: url
