我想对数组中的散列进行排序

Question

a = [{"name"=> "ted","age"=>1}, 
    {"name"=> "mika","age"=>2}, 
    {"name"=> "bob","age"=>0}] 

如何使用ruby程序对年龄顺序（升序）的数组进行排序？

我想成为以下人员。

a = [{"name"=> "bob","age"=>0}, 
    {"name"=> "ted","age"=>1}, 
    {"name"=> "mika","age"=>2}] 

Answer 1

由于卡里Swoveland在评论说，

a.sort_by { |h| h["age"] } 

我能做的above.thanks。
