Setting a variable dynamically in rails

Question

Is it possible for me to dynamically determine a field name or variable, e.g.

module ApplicationHelper
def current_week
  1
end

Controller
def @player = Player.find(params[:id]) 

/item/show.html.erb
<%= @player.total_for_week_{current_week} %>

This way I can update the current_week variable, either manually or based on a formula, and have it flow to all of my views. Is there a way to do this?

Thanks!

<%= @player.send("total_for_week_#{current_week}") %>

This will work, but it strikes me as hackish and probably more complicated than it needs to be. Can't you just have a method on player called total_for_current_week? Then have that method reference your current_week variable directly? Part of it is a question of who should keep track of the current_week.
