Active Model Translation

Provides integration between your object and the Rails internationalization (i18n) framework.

A minimal implementation could be:

class TranslatedPerson
  extend ActiveModel::Translation
end

TranslatedPerson.human_attribute_name('my_attribute')
# => "My attribute"

This also provides the required class methods for hooking into the Rails internationalization API, including being able to define a class-based i18n_scope and lookup_ancestors to find translations in parent classes.
