在ruby中合并一些复杂的哈希值

Question

我想将以下哈希合并在一起.

 h1 = {"201201" => {:received => 2},   "201202" => {:received => 4 }}
 h2 = {"201201" => {:closed => 1},  "201202" => {:closed => 1 }}

特别是,我的预期结果是:

h1 = {"201201" => {:received => 2, :closed => 1},  "201202" => {:received => 4, :closed => 1 }}

我尝试过各种方式:

h = h1.merge(h2){|key, first, second| {first , second} }

不幸的是,似乎对我来说都没有好处.任何建议都会非常感激.

Answer 1

这应该适合你:

h = h1.merge(h2){|key, first, second| first.merge(second)}
