Rails - Feb 2008 - What to use in place of components using a "static" controller.

I''m working on a site that has a lot of static and semi-static pages.
I''m using a StaticController to keep everything DRY and allow for erb
code in the pages when necessary:

class StaticController < ApplicationController

  def display_page
    begin
      render(:template =>
"static/#{params[:path].join(''/'')}")
     rescue
      render(:template => "static/404", :status => 404)
    end
  end

  def index
    render(:template => "static/home")
  end

end

Some of these pages contain components (such as a news feed), which
I''ve been assured are Not A Good Thing. Instead, I''ve been
told to use
partials and :before_filter to get the same results. However, in this
case, a :before_filter is not an option because there is only one
action to render all static pages. The only alternative seems to be
grabbing the data in the partial itself, which does not seem to be
proper separation. What should I do?
