Rails - Mar 2014 - Use a module for this?

Hi,

I have some code that has to be used by more than one method in the same
class.  Would I create a module for this or is there a better way?

eg.
module QuestionSequencer
   class Sequence

 def sequence_questions
      initial_now_playing_length = play_list[0].length
      now_playing = play_list[0]
      clone_number = 3
      order = "random"  # $$$Variable
      if order == "random"
        now_playing_temp = Array.new
        for i in 1..clone_number
          now_playing = now_playing.dup.shuffle
          now_playing_temp = now_playing_temp + now_playing
        end
        now_playing = now_playing_temp
        for d in 1..clone_number  # Check for sequential duplicates:
         if now_playing[(initial_now_playing_length * d) -1 ]
=now_playing[initial_now_playing_length * d]
            value = now_playing.delete_at(initial_now_playing_length *
d)
            now_playing.insert(now_playing.length, value)  # Reinsert
the item in a new position
          end
        end
      else # Sequential
        now_playing = now_playing.dup * clone_number
      end
      now_playing

    end
  end
end

in method:
     now_playing = play_list.sequence_questions
in model:
    include QuestionSequencer

This is not working but would like to know if I'm at least going in the
correct direction.

Thanks,
Dave
