Rails - Nov 2005 - Dynamic forms

All,

   if I have an object defined as follows:

   class Fred
      attr_accessor :fields

      def initialize
         @fields = Hash.new
      end
   end

   If want to display the keys in Fred map in a form thus doing 
something
   like

   <%= text_field( ''myFred'', ''(?? WHAT DOES THIS
LOOK LIKE ??)'' ) %>

   The issue is what does the databinding expression look like and
can''t
this
   be achieve with Rails ?
   For instance if the hash contains a key ''name'' that is the
field I
want to
   interact with on the form. This would be the equiv of struts 
dynaforms..

   Any ideas ? Rails gods and goddesses, Please help....
