Loop of Properties

I'm starting in RoR, sorry if this question seems too basic.

See the code below. The second parameter of the method Rails3AMF:
IntermediateModel.new must pass ALL properties "field". How do I
implement a loop that does this?

Thanks,

Saulo

class User
  include Mongoid::Document
  include ActiveRecord::Serialization

  field :name, :type => String
  field :email, :type => String
  field :username, :type => String
  field :password, :type => String

  def to_amf options=nil
    Rails3AMF::IntermediateModel.new(self, {"name" => self[:name],
"email" => self[:email], ... } )
  end

Can't you just use Rails' validations for this? Am I missing something?

end

Best,
