使用Ruby将2个哈希值合并为1个

Question

我有2个哈希值，需要使用Ruby对值进行合并

hoh = Hash.new
hoh = {"bob::params::search_vol_grp"=>{2=>{"search_group_id"=>2, "vol_ids"=>"2,627,628", "num_shards"=>32, "num_replicas"=>1}, 3=>{"search_group_id"=>3, "vol_ids"=>"3,629,630", "num_shards"=>32, "num_replicas"=>1}, 4=>{"search_group_id"=>4, "vol_ids"=>"4,631,632", "num_shards"=>32, "num_replicas"=>1}}
hob = Hash.new
hob = {"bob::params::search_q_broker"=>{2=>{"master_host"=>"hq01p1", "master_port"=>"61616", "slave_host"=>"hq01p2", "slave_port"=>"61616"}, 3=>{"master_host"=>"hq01p1", "master_port"=>"61616", "slave_host"=>"hq01p2", "slave_port"=>"61616"}, 4=>{"master_host"=>"hq01p1", "master_port"=>"61616", "slave_host"=>"hsq01p2", "slave_port"=>"61616"}}

我要结束的是以下内容-

hon = Hash.new
hon = {"bob::params::search"=>{2=>{"master_host"=>"hq01p1", "master_port"=>"61616", "slave_host"=>"hq01p2", "slave_port"=>"61616", "search_group_id"=>2, "vol_ids"=>"2,627,628", "num_shards"=>32, "num_replicas"=>1}, 3=>{"master_host"=>"hq01p1", "master_port"=>"61616", "slave_host"=>"hq01p2", "slave_port"=>"61616", "search_group_id"=>3, "vol_ids"=>"3,629,630", "num_shards"=>32, "num_replicas"=>1}, 4=>{"master_host"=>"hq01p1", "master_port"=>"61616", "slave_host"=>"hq01p2", "slave_port"=>"61616", "search_group_id"=>4, "vol_ids"=>"4,631,632", "num_shards"=>32, "num_replicas"=>1}}

我已经尝试了各种使用合并和合并的尝试！ 但都没有产生我想要的最终结果。

有小费吗？

编辑根据拉里的建议，我可以通过以下方法实现我想要的功能

hon = Hash.new
hon['bob::params::search'] = Hash.new
hoh.each do |key,value|
  value.each do |k, v|
    hon['bob::params::search'][k] = hoh['bob::params::search_vol_grp'][k].merge! (hob['bob::params::search_q_broker'][k])
  end
end

我还更新了第二个哈希，以使用一个Fixnum而不是Darshan指示的字符串。

感谢所有的指针家伙！

Answer 1

为您的哈希提供有效的变量名，关闭哈希，并使第二个哈希使用Fixnum而不是String作为顶级键，这似乎可以满足您的要求：

h1 = {2=>{"search_group_id"=>2, "vol_ids"=>"2,627,628", "num_shards"=>32,
          "num_replicas"=>1}}
h2 = {2=>{"master_host"=>"hsrchq01p1", "master_port"=>"61616",
           "slave_host"=>"hsrchq01p2", "slave_port"=>"61616"}}

h1.merge(h2){|key, first, second| first.merge(second)}
# => {2=>{"search_group_id"=>2, "vol_ids"=>"2,627,628", "num_shards"=>32,
#         "num_replicas"=>1, "master_host"=>"hsrchq01p1", "master_port"=>"61616",
#         "slave_host"=>"hsrchq01p2", "slave_port"=>"61616"}}

Answer 2

像这样

1[2].merge(2[2])

您需要合并内部哈希。
