Seems reasonable. As long as you're sure your cache will expire the old entries and not keep piling them up until you run out of ram/disk space. I would consider adding a generic method to all your models named say "fragment_key" that does whatever is necessary to generate a unique key. That way in your controllers/views you never have to think what fields to put in there to get the right version. It's always just @instance.fragment_key. And you can hash that if you want to shorten it down and avoid any key length issues or invalid characters, etc. You might also find this interesting... http://blog.plataformatec.com.br/2009/09/how-to-avoid-dog-pile-effect-rails-app/ -philip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
