So lets say I have a class like below

class List
  include DataMapper::Resource
  property :id, Serial  
  property :username, String

  def self.my_username
    return self[:username]
  end
end

list=List.create(:username=>,'jim')
list.my_username

When I run this it tells me that the method cannot be found, and on more investigation that you can only define class methods(not object methods) and that class methods don't have access to objects data.

Is there any way to have these methods included as object methods and get access to object data? I'm using Ruby 1.8.6 and the latest version of datamapper.
