ruby - カスタム形式で配列を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のを手伝ってもらえますか？

配列

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

ハッシュ

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

Answer 1

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"}}

Answer 2

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"}
