hi , how can i deploy it to GAE , & should i conigure app,yaml & config.ru?

Yeah, I'm not sure but this seems a little incomplete.

Would appreciate a hand as I've tried a few times myself to get Rails 3 running using modifications (there were lots) to the Rails 2 on GAE gist you have. I got there but I was finding the app slower with every page load since deployment so I was going wrong somewhere.

However your method looks much more appealing if it uses ActiveRecord instead of DataMapper (I used ActiveRecord on my Rails applications before coming to the world of GAE).

Thanks.
