Ruby 抓取信息并将其显示在密钥中=>；嵌套哈希中的值样式？

我有以下资料：

  department = data.css('#ref_2619534011')

  @department_hash = Hash.new {|h,k| h[k]=[]}
  department.css('.narrowValue').each do | department |
    @department_hash["department"] << department.text
  end 

现在我想抓住这些总数的标题

 department.css('.refinementLink').each do

其输出如下：

{"department"=>["15,721", "243,247", "510,260", "46,007", "14,106", "358", "5,787", "19,808"]}

{"department"=>["Bird", "Cats", etc ]}

{departments: { "Pet Supplies": [ "Birds" : 15,721, "Cats" : 243,247, etc ] }}

我想混合这两种方法来生成一个嵌套哈希，如下所示：

{"department"=>["15,721", "243,247", "510,260", "46,007", "14,106", "358", "5,787", "19,808"]}

{"department"=>["Bird", "Cats", etc ]}

{departments: { "Pet Supplies": [ "Birds" : 15,721, "Cats" : 243,247, etc ] }}

如何做到这一点

编辑：

我试过了，但没有成功：

 @department_hash = Hash.new {|h,k| h[k]=[]}
  department.css('li').each do | department |
    department_title = department.css('.refinementLink').text
    department_count = department.css('.narrowValue').text[/[\d,]+/]
  end 

  @department_hash["department"] = Hash[department_title.zip(department_count)]

您可以使用组合两个阵列：

numbers = ["15,721", "243,247"]
animals = ["Birds", "Cats"]

Hash[animals.zip(numbers)]
#=> {"Birds"=>"15,721", "Cats"=>"243,247"}

关于您的编辑：

由于您已经准备好了

部门标题

和

部门计数

，在您的循环中类似的内容应该可以工作：

@department_hash = {}
department.css('li').each do |department|
  department_title = ...
  department_count = ...
  @department_hash["department"] ||= {}   # ensure empty hash
  @department_hash["department"][department_title] = department_count
end

我试着将它合并到我的代码中，但没有成功。请看我的EDIT@alexchenco

department\u title

和

department\u count

在您的循环之外不可用。我已经更新了我的答案。非常感谢！顺便问一下，我如何添加“宠物用品”部分（只是作为嵌套哈希的标题？）我认为

@department\u hash[“department”][“Pet Supplies”]=…

是您要寻找的语法。
