试试这个：

  my_array.find {| X | x.some_test}
 

或者这里是一个快捷方式（感谢@LarsHaugseth提醒一下吧）

  my_array.find（安培;：some_test）
 

Is there a shorter way to find the first element in an array meeting some conditions than this:

my_array[ my_array.index {|x| x.some_test} ]

Try this:

my_array.find{|x| x.some_test }

Or here's a shortcut (thanks @LarsHaugseth for reminding about it)

my_array.find(&:some_test)
