Class Table Inheritance implementation
I know that Rails uses the Single-Table Inheritance as mentioned in the
wiki (http://wiki.rubyonrails.com/rails/pages/SingleTableInheritance). I
was wondering if there was an easy way of implementing Class Table

Did DHH have a suit on?

the like in Rails.
I''ve always thought that perhaps DHH found himself in a suit one day
(maybe he had to attend a friend''s wedding or something), and as long as
he had the suit on, decided to lapse into a one of the barely lucid
frenzies that Marketing people are prone to when

Table Inheritance based on a function
Hello,
we have a problem in a CMS project that we believe is basic for RoR
developement and could concern others as well - or have already:
RoR implements the ''Single Table Inheritance'' (STI) Pattern:
http://www.martinfowler.com/eaaCatalog/singleTableInheritance.html
.. through its ''ActiveRecord'' ORM.
The Fowler example mentions a ''type'' column and RoR implements this
directly - which we consider inconsistent with DB abastraction:
It forces a ''type'' column in the database followi...
