If you’ve waited until now before upgrading to Ruby on Rails 2.0 now you may be in for a little surprise. As of version 2.02 the default database in Rails is SQLite, arguably because there is no need to for grants or the creation of tables, meaning a simpler setup for n00bs. If you still want to use MySQL (or any other database for that matter) you have to provide the following:
rails -d mysql appname
SQLite3 and the necessary driver gems come preinstalled on OS X Leopard, but if you don’t have the Ruby bindings installed it’s as simple as:
sudo gem install sqlite3-ruby
You can always change which db your Rails app is using by changing your config/database.yml.
