Can't get this code work on challenge 2

Build a custom validator that ensures that no Contact’s last_name is Evil.

contact.rb 
 class Contact < ActiveRecord::Base

  validate :evil_in_last_name
    if last_name.include?("Evil")
      errors.add(:last_name, " name already taken")
    end
  end

Quite closed, but you need to define a method for the validator; so wrap this block of code

    if last_name.include?("Evil")
      errors.add(:last_name, " name already taken")
    end

into a method named evil_in_last_name.

Final code should be like this

class Contact < ActiveRecord::Base
  validate :evil_in_last_name
  def evil_in_last_name
    if last_name.include?("Evil")
      errors.add(:last_name, " name already taken")
    end
  end
end
