ActiveModel::Translation (original) (raw)

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.

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.

translation = I18n.translate(defaults.shift, count: 1, raise: raise_on_missing, **options, default: defaults) if translation == MISSING_TRANSLATION translation = attribute.present? ? attribute.humanize : namespace.humanize end translation end

i18n_scope()Link

Returns the i18n_scope for the class. Override if you want custom lookup.

def lookup_ancestors ancestors.select { |x| x.respond_to?(:model_name) } end
