Rails3 and Datamapper quick start May 21st, 2010



Rails3 is almost released and I decided to try it out with Datamapper to see how things work. Things work AWESOME!

Here's a rundown of the steps I used: 


gem update --system # you need rubygems >= 1.3.6
git clone http://github.com/rails/rails.git
cd rails
rake install
cd ..
rails my_dm_rails3_app -m http://github.com/jeremyd/rails-templates/raw/master/dm_rails_master.rb
cd my_dm_rails3_app
bundle install
Note: I cloned snusnu's repository here and modified to install a Gemfile that uses prerelease rubygems instead of git repository checkouts. This seems much faster and there were less dependency problems for me..
