使用自定义格式将数组转换为哈希

Question

有人可以帮我将以下数组转换为具有以下格式的哈希吗？

阵列

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

哈希

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"}
