Rails - Apr 2006 - how to map one-to-one relation to two tables

hi. iv got a problem with one-to-one relation with AR. let''s say I need
this classes:

class ContentObject < ActiveRecord::Base
class BlogEntry < ContentObject
class FotoEntry < ContentObject

i.e. Blog and Foto entries must extend ContentObject. Also they must be 
mapped to separate tables. I can not figure out how to map this kind of 
association better?

The most dumb and straitforward way is actually NOT to extend 
ContentObject and associate it as regular has-one and belongs-to, but 
that way all beauty will b gone, since i''ll need manually treat object 
instantiation etc., maybe there are much more elegant ways to solve this 
kind of problems?

How about:

module ContentBehaviour
   #whatever behaviour is shared
end

class BlogEntry < ActiveRecord::Base
   include ContentBehaviour
end

class FotoEntry < ActiveRecord::Base
   include ContentBehaviour
end
