Displaying the last 10 pages visited from a session

I wanted to store and display an array of the last 10 visited pages in a session. With the help of some folks in #rubyonrails (particularly aqua) this is what i've come up with:





class ApplicationController < ActionController::Base

	before_filter :add_to_history

	before_filter :page_title

	

	def add_to_history

	  session[:history] ||= []

	  session[:history].unshift ({"url" => @request.request_uri, "name" => page_title })

	  session[:history].pop while session[:history].length > 11

	end





# This bit came from Peter Cooper's snippets source and was moved into the application controller:



	def page_title

		case self.controller_name

			when 'tag' 

				title = "Tags » " + @params[:tags].join(" > ")

			when 'user'

				title = "Users » #{@params[:user]}"	 

			when 'features'

					case self.action_name

						when 'show' then title = "Feature » #{Feature.find(@params[:id]).title}"

						else title = APP_CONFIG["default_title"]

					end

			else 

				title = APP_CONFIG["default_title"] + self.controller_name + ":" + self.action_name

		end

	end

	helper_method :page_title



...

end

In your partial you might do something like this:





User History

<% for cur in session[:history][0..9] -%>

  "><%= cur["name"] %>

<% end -%>

Feedback and comments would be appreciated
