12. class Event < ActiveRecord::Base include I18n::Alchemy localize :starts_at, :ends_at, :price end I18nAlchemy
13. class Event < ActiveRecord::Base include I18n::Alchemy localize :starts_at, :ends_at, :price end I18nAlchemy
14. I18n.with_locale :pt do @event.localized.starts_at = '30/08/2012' @event.starts_at # => Date.new(2012, 08, 30) @event.localized.starts_at # => '30/08/2012' @event.localized.price = '150,00' @event.localized.starts_at = 3.days.ago @event.save! end I18nAlchemy
15. .localized?
16. .localized? • I18n::Alchemy::Proxy
17. .localized? • I18n::Alchemy::Proxy • Nada de sobreescrever acessores
18. .localized? • I18n::Alchemy::Proxy • Nada de sobreescrever acessores • Manipula apenas os atributos configurados
19. I18nAlchemy class Product < ActiveRecord::Base include I18n::Alchemy localize :total, :using => :number def total quantity * price end end
20. I18nAlchemy • Configurações através do i18n • Não é dependente do ActiveRecord • Escreva os seus próprios parsers!
21. module MyParser def self.parse(value) # ... end def self.localize(value) # ... end end class Product < ActiveRecord::Base include I18n::Alchemy localize :total, :using => MyParser end
