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.

Instance Public methods
human_attribute_name(attribute, options = {}) Link
Transforms attribute names into a more human format, such as “First name” instead of “first_name”.
Person.human_attribute_name("first_name") # => "First name"
Specify options with additional translating options.

i18n_scope() Link
Returns the i18n_scope for the class. Override if you want custom lookup.
lookup_ancestors() Link
When localizing a string, it goes through the lookup returned by this method, which is used in ActiveModel::Name#human, ActiveModel::Errors#full_messages and ActiveModel::Translation#human_attribute_name.
