Category: Ruby on Rails tutorials > Routes - Difficulty:

I'm a ruby and rails newcomer, and for my wordpress blog "nubyonrails" decided to work through David Heinemeier Hansson's famous "blog site" Rails demo movie, from the FISL 6.0 conference in Brazil, 2005. It's written for fellow ruby/rails newcomers but covers quite a lot of ground.
