First of all, you don't need to use "end" with Haml. You can use indentation
instead to delineate the structure of blocks and statements. for example:
!!! XML
!!! 1.1
%html{ html_attrs('fr-fr') }
%head
%title= yield :title
%body
- [:notice, :error, :message].each do |key|
- unless flash[key].blank?
%p{ :class => "flash flash_#{key}" }= flash[key]
#contents
= yield
I'm not sure what's wrong with the second example. You'll have to give more
information about the erroneous output.
