Rails 3 no longer auto loads the lib folder. We can make it auto load the lib folder by putting it in config/application.rb like thus: config.autoload_paths += %W(#{config.root}/lib)

All strings are HTML escaped by default in Rails 3. Need to call html_safe on strings which we know are sure to be safe to display the HTML properly.

Reserved words: "config", "process"

Specifying RailsEnv in Apache configuration (vhost/httpd.conf etc) for Passenger 3.0.0 does not work in Rails 3. Changing that to RakeEnv does the trick. This was fixed in Passenger 3.0.1.

To add the default integer primary key to a table which was created with :id => false setting, we can do add_column :table_name, :id, :primary_key
