Question

I have a condition where if action_name contains “index” then the second class should return “index” only, otherwise, set it to action_name.

I was trying something along these lines:

  - if action_name =~ /.*index.*/
    %body{ :class => "#{controller_name} index" }
  - else
    %body{ :class => "#{controller_name} #{action_name}" }

Unfortunately I have the remainder of my body in the layout that follows these and it is only displayed for the else clause.

I figure there is a more readable one liner that I could use here as well that would perform an if within the line vs the more verbose multiline if statement, but I could use some help here in terms of gettin this to work as expected in HAML.

Well, here’s a one liner:

%body{ :class => "#{controller_name} #{(action_name =~ /.*index.*/) ? 'index' : action_name}" }

Not that readable though!
