Note that you can have multiple associations into the same table using
and :class_name option.  So for example
class Something
  belongs_to :give, :foreign_key => "give_id", :classname => "Widget"
  belongs_to :take, :foreign_key => "take_id", :classname => "Widget"

Have a look at the Rails Guide on ActiveRecord Associations for more
information.
