我想从Array / Hash构造以下YAML格式：
Name:
gender:
- female
nationality:
- german
- danish
现在我有一个像这样的数组： names = ["Abbie","Abeline","Abelone"] 从这个数组到YAML最简单的方法是什么？ 我尝试将其转换为哈希,同时添加性别和国籍的值： names.each do |name|
(META_HASH ||= Hash.new) = name => { gender: 'female',nationality: ['german','danish'] }
end
但是,这只会给我一个语法错误.任何帮助转换这将非常感谢！ 解决方法> require 'yaml'
> names = ["Abbie","Abelone"]
=> ["Abbie","Abelone"]
> puts names.to_yaml
---
- Abbie
- Abeline
- Abelone
=> nil
> h = {:name => { gender: 'female','danish'] }}
=> {:name=>{:gender=>"female",:nationality=>["german","danish"]}}
> puts h.to_yaml
---
:name:
:gender: female
:nationality:
- german
- danish
=> nil
> a = names.map { |n| { n => { gender: 'female','danish'] } } }
> puts a.to_yaml
---
- Abbie:
:gender: female
:nationality:
- german
- danish
- Abeline:
:gender: female
:nationality:
- german
- danish
- Abelone:
:gender: female
:nationality:
- german
- danish
=> nil
