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?
