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
.
