Answer 2

Yes, for example using the validations:

require 'active_model'

class Cat
  include ActiveModel::Validations

  attr_accessor :id, :name

  validates_presence_of :name
  puts "meow!"

end

Testing out 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
