Question

Using Rails 3, but I guess doesn’t matter. I put this in the template helper.

It always goes to the last case badge-warning when I for whatever value I put for rating, such as rating_badge(4):

  def rating_badge(rating)
    case rating
    when rating > 3
      'badge-success'
    when rating < 3
      'badge-important'
    else
      'badge-warning'
    end
  end

What went wrong?

Answer 1

You have a stray rating variable at the top of your case statement. The correct syntax is:

case
when rating > 3
  'badge-success'
when rating < 3
  'badge-important'
else
  'badge-warning'
end

This works for me at the REPL using pry and irb.
