深红宝石不同哈希类型

Question

我这个问题挣扎合并，我无法弄清楚如何做到这一点。让我们假设我有两个散列：

hash1 = { "address" => "address", "phone" => "phone } 
hash2 = { "info" => { "address" => "x", "phone" => "y"}, 
      "contact_info" => { "info" => { "address" => "x", "phone" => "y"} }} 

我希望得到如下的输出：

{ "info" => { "address" => "address", "phone" => "phone"}, 
    "contact_info" => { "info" => { "address" => "address", "phone" => "phone"} }} 

我试过Hash#deep_merge但它并没有解决我的问题。我需要的是能够合并第二个散列表中任何位置的所有键和值的东西，无论它的结构如何。

我该怎么做？任何线索？

我想你想递归合并HASH1？也许这：

class Hash 

    def deep_merge_each_key(o) 
    self.keys.each do |k| 
     if o.has_key?(k) 
     self[k] = o[k] 
     elsif self[k].is_a?(Hash) 
     self[k].deep_merge_each_key(o) 
     end 
    end 
    self 
    end 
end 

h1 = {"address"=>"address", "phone"=>"phone"} 
h2 = { 
    "info" => { "address" => "x", "phone" => "y"}, 
    "contact_info" => { "info" => { "address" => "x", "phone" => "y"} } 
} 

puts h2.deep_merge_each_key(h1).inspect 

# => {"info"=>{"address"=>"address", "phone"=>"phone"}, "contact_info"=>{"info"=>{"address"=>"address", "phone"=>"phone"}}}
