def method_for_controller_entire app)one
render(:controller => 'controller_two', :action => 'rss')
end
but instead of using a view rss.rhtml, I want to use a Builder
template rss.rxml that's in the controller_two directory for display.
I hate to have the same rss.rxml file in multiple controller
directories, but can't figure out how to reuse the same template.
render :template takes a template path from your view root (ie /app/
views). render :partial is also able to do stuff like render :partial
=> 'somewhere_else/foo'
