# Refactor if function in ruby/rails [closed]

working on a rails app that doesn't seem to want to run 'Until' or 'While' functions. Having to do the following:

<% if q == 2 or q == 5 or q == 8 or q == 11 or q == 14 or q == 17 or q ==20 %>

Any suggestions for how I can improve this?

Try something like <% if q in [2,5,8,11,14,17,20] %> - not sure if ERB allows this though. –  Ash Dec 11 '12 at 21:07
OK that doesn't work. Try: <% if [2,5,8,11,14,17,20].include? q %> –  Ash Dec 11 '12 at 21:10
What are you trying to accomplish? A loop with a step of 3? In that case try (2..20).step(3) do ... end –  Flambino Dec 11 '12 at 22:22

if (q % 3 == 2) && (q <= 20)
