Defined in:
lib/i18n_accessors/methods.rb

Overview

Defines methods for a set of locales to access translated attributes in those locales directly with a method call, using a suffix including the locale:

article.title_pt_br

If no locales are passed as an option to the initializer, I18n.available_locales will be used by default.

Examples:

class Post
  def title
    "title in #{I18n.locale}"
  end
  include I18nAccessors::Methods.new("title", locales: [:en, :fr])
end

I18n.locale = :en
post = Post.new
post.title
#=> "title in en"
post.title_fr
#=> "title in fr"
