配列をカスタム形式のハッシュに変換する

Question

誰かが次の配列を次の形式のハッシュに変換する手助けができますか？

アレイ

[["0", {"checkbox_2"=>"on"}], ["2", {"checkbox_1"=>"on"}]]

ハッシュ

search=>{"checkbox_2"=>"on", "checkbox_1"=>"on"} 

Answer 1

arr = [["0", {"checkbox_2"=>"on"}], ["2", {"checkbox_1"=>"on"}]] 
hash = Hash[arr.flatten.select{|e| e.is_a? Hash}.collect{|e| e.to_a.flatten}] 
=> {"checkbox_2"=>"on", "checkbox_1"=>"on"} 

Answer 2

xs = [["0", {"checkbox_2"=>"on"}], ["2", {"checkbox_1"=>"on"}]] 
search = {:search => xs.map { |n, h| h }.inject(:merge)} 
# {:search=>{"checkbox_2"=>"on", "checkbox_1"=>"on"}}
