Rails 3 Notes
From Rory.wiki
Security
In application.rb there's a parameter config.filter_parameters which is an array containing paramters which shouldn't be logged. By default the only element getting added to it in this file is :password. Wonder if other fields like :confirm_password get logged then?
Setting the home page
Modify config/routes.rb add a line root :to => "<modelnameplurak>#index" . eg if you want the root page a model called posts root :to => "posts#index" . Also remove the index.html file from /public.
