Rails - Apr 2006 - Using Paginator outside of controllers

I am doing this in _messages.rthml:
<% shout_pages = Paginator.new self,
							   Shout.length,
							   30,
							   @params[''page''] %>
<% shouts = Shout.find :all,
					   :order => "timestamp desc",
                        :limit => @story_pages.items_per_page,
                        :offset => @story_pages.current.offset %>



I am calling the _messages.rhtml with:
<%= render :partial => ''/shout/messages'' %>

However, I keep getting "uninitialized constant Paginator"

Is this normal? Are you supposed to be able to use Paginator outside  
of controllers?
