Accessing Route helpers in rails 3.2

I'm migrating a rails 2.3 app to rails 3.2. I have an object used to manage the caching of a few stats I collect from different sources. As the collection process is quite long, It couldn't be done with the traditional fragment caching. I had to fill the cache asynchronously. the AsynchCache object, get data from Google Analytics and stores the content of a partial in the cache. ``` include Rails.application.routes.url_helpers class AsynchCache def self.get_popular_races_from_google_analytics(lang='en') # getting info form GA using Garb. end def self.set_popular_races(language=nil) av = ActionView::Base.new(Rails.configuration.paths['app/views']) language_list = Global.instance.languages_UI.map{|a| a[0]} for lang in language.nil? ? language_list : [language] output = av.render( :partial => "home/popular_races", :locals => {:lang => lang} ) Rails.cache.delete("popular_races_#{lang}") Rails.cache.write("popular_races_#{lang}",output) end end def self.get_popular_races(lang='en') Rails.cache.read("popular_races_#{lang}") end end ``` The partial I used for the display is as follows - "> tmp_race.name -%> When I want to display the content, I just have to use : ``` <div id="popular_races"> <%# AsynchCache.get_popular_races(params[:locale])-%> </div> ``` It works fine when I first load the page, or in irb, but if I try to reload the page or set in development.rb config.cache_classes = true, I get an error : ``` stack level too deep Rails.root: /Users/macbook/Sites/marathons Application Trace | Framework Trace | Full Trace actionpack (3.2.1) lib/action_dispatch/middleware/reloader.rb:70 ``` If I remove include Rails.application.routes.url_helpers, i don't get the error, but of course, I don't have acccess to the routes. Is there a new way to get the route methods from a model in rails 3.2?
