With Rails 3 you can! Check out this post on Rubyinside.com

Answer 2

Yes, for example, using checks:

require 'active_model' class Cat include ActiveModel::Validations attr_accessor :id, :name validates_presence_of :name puts "meow!" end 

Testing the class above:

 $ irb -r ./cat.rb meow! irb(main):002:0> cat = Cat.new => #<Cat:0xb99e44> irb(main):003:0> cat.valid? [deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message. => false irb(main):004:0> cat.name = "puss" => "puss" irb(main):005:0> cat.valid? => true
