Ruby and Rails and Haml - putting ruby code into the haml page

Question

I am trying to figure out how to put Ruby code into a HAML file so I can determine which controller the request came through, and set some appropriate settings.

I added this code to the top of the file:

ruby:
  active_is = "#{request[:controller]}/#{action_name}"

But it crashed with the error saying:

Illegal nesting: nesting within plain text is illegal.

Does that mean that my syntax is off? How do I fix this?

Thanks!

Language filters are preceded by the colon, not the reverse:

:ruby
  active_is = "#{request[:controller]}/#{action_name}"

More often than not, though, it's easier to just use - :

- active_is = "#{request[:controller]}/#{action_name}"
