如何将类似于此｛｛｝｝的哈希转换为类似于此{｛[]｝}的哈希

Question

所以这是我正在使用的代码：

  @department_hash = {}
  department.css('li').each do | department |
    department_title = department.css('.refinementLink').text
    department_count = department.css('.narrowValue').text[/[d,]+/]
    @department_hash[:department] ||= {}
    @department_hash[:department]["Pet Supplies"] ||= {}
    @department_hash[:department]["Pet Supplies"][department_title] = department_count
  end 

它产生了这样的东西：

｛：department=>｛"宠物用品"=>｛"=>零，"Birds"=>"15863"，"猫"=>"243396"，"狗"=>"512965"，《鱼类和水生宠物》=>"46428"，"马"=>"14738"，"昆虫"=>"360"，"爬行动物&两栖动物"=>"5843"，"小动物"=>"19871"｝｝

但我想要的是生产这样的东西：

{：部门=>{"宠物用品"=>["=>零，"鸟类"=>"15863"，"猫"=>"243396"，"狗"=>"512965"，《鱼类和水生宠物》=>"46428"，"马"=>"14738"，"昆虫"=>"360"，"爬行动物&两栖动物"=>"5843"，"小动物"=>"19871"]}｝

我该如何做到这一点？

编辑：

这个怎么样？这是有效的ruby代码吗？

departments: { "Pet Supplies": [ "Birds" : 16651, "Cats" : 242910, etc ] }

Answer 1

你不能。

你能做的最好的事情是这样的：

{ foo: [ { key: :value }, { key: :value } ] }

为此：

@department_hash = {}
  department.css('li').each do | department |
    department_title = department.css('.refinementLink').text
    department_count = department.css('.narrowValue').text[/[d,]+/]
    @department_hash[:department] ||= {}
    @department_hash[:department]["Pet Supplies"] ||= []
    @department_hash[:department]["Pet Supplies"] << { key: :value } # replace with your own hash
  end 
end
