Instance Method Details

#translatable_attribute_accessor(*attributes) ⇒ Object

Adds a reader and writer for each available locale for each of the given attributes. For example (and assuming that the available locales are :en and :de):

I18n.available_locales                            # => [:en, :de]

class Post < ActiveModel::Base
  translatable_attribute_accessor :title, :body
end

This creates the methods ‘title_en`, `title_en=`, `title_de`, `title_de=`, `body_en`, `body_en=`, `body_de` and `body_de=`
