Question

I ve got a yaml file document which have similar keys :-

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

在编造新档案之后。 key 钥匙按字母顺序分类:

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

开放式样本-档案和制作新档案的代码如下:

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 ]))

I m using "ya2yaml" gem for generating yaml file. In order to get the same order as it s in sample_file.yml i ve used hash_order here `@new_file.syswrite(@file.ya2yaml(:hash_order => [ title , department , input_formats ]))`, but it s not working. How can i retain the order?

Answer 1

Finally i got the solution of the ordering issue.

The :hash_order only work for top level hash.
so it works only when i remove "line" key from my sample_file.yml. Then the order is preserved. :-

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

您能否改变阿盟档案的格式? 你们的《马列》档案中专门有一只带有重复钥匙的散射。这是无。

如果有的话,阿盟档案也使用一个清单。

line:
    title: line-name
    department: transcription

    formats:
        - input_format:
          name: company
          required: true
          valid_type: general

        - input_format:
          name: website
          required: false
          valid_type: url
....

这些额外的 da子将解决你的问题。

YAML意在储存关键价值乳制品,因此其定购单对YA马尤其重要。

</em>解决你的问题,是用1.9.2鲁比语解决的,这符合在海螺中插入顺序(在Rub.1.8.7中是一例)。

sample_file.yml

new_file.yml

I m using "ya2yaml" gem for generating yaml file. In order to get the same order as it s in sample_file.yml i ve used hash_order here @new_file.syswrite(@file.ya2yaml(:hash_order => [ title , department , input_formats ])), but it s not working. How can i retain the order?
