The dutchify plugin deals with:

• ActiveRecord model names and columns can easily be translated in the model class.
• The default validation messages in ActiveRecord have been translated.
• Dynamic scaffolding is in dutch.
• Date and Time, both will display and parse dutch formatted dates.
• Integer#ordinalize and String methods pluralize, camelize, underscore and titleize have been dutchified. Although the plugin doesn’t do real pluralization since it is quite hard in dutch.
• View helpers for numbers and dates are translated to dutch.
