ruby - 在 ruby​​ 中合并一些复杂的哈希

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 }}

我已经尝试了各种方法：

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

不幸的是，对我来说，两者似乎都不是很好。任何建议将不胜感激。

Answer 1

这应该适合你：

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