Once the plugin is installed, dumping a fixture is a simple matter of invoking a new rake task called rake db:fixtures:dump. Unlike the built-in loading rake task, this one takes a MODEL parameter with the name of the ActiveRecord class that you want to dump data for:
$ rake db:fixtures:dump MODEL=BillingCode
