Ruby 从一个哈希元素具有最高值的数组中选择单个哈希

从下面的哈希数组中，如何选择

timestamp

具有最高值的单个哈希

data = [
  {"id" => 1, "timestamp" => 1383314276, "data" => "bea7c82f-f4b2-492a-aba3-033b1a54d9d0"},
  {"id" => 2, "timestamp" => 1383314386, "data" => "64ed2ed9-763d-443f-a74e-e7f10cbe783e"},
  {"id" => 3, "timestamp" => 1383314331, "data" => "f8cfaa99-ffe0-4d88-8fac-37e4ce462d3a"}
]

在这里你可以看到：

 data.max_by{|e| e["timestamp"] }
 # >> {"id"=>2, "timestamp"=>1383314386, "data"=>"64ed2ed9-763d-443f-a74e-e7f10cbe783e"}
