title: Allowing users to choose custom theme in Rails
body: <p>I want to give my users the ability to choose how their public page is displayed from 5 different layouts. I assume I'll need 5 different css files according to layout and then need to pass that into stylesheet_link_tag</p>
  
  <p>I know only how to do it using if then statements. I don't suppose that is the best way. Any help...also could it be done?</p>
  
  <p>Thanks</p>
