I’ve looked at these methods using PostgreSQL, and they seem fine for

Something to think about…

An ORM that I’ve seen able to implement CTI and polymorphic object calls
SQLObject v7 by Ian B… It’s written in Python.

I really miss CTI in RoR. Expecially for the ‘CMSish’ scenarios
described in
this thread, where STI doesn’t make sense at all.

Is anybody developing CTI for Rails?!?
