Hi there, I am just getting my feet wet with postmodern. It looks like I will be doing some heavy development with it for the next couple of weeks. Wish me luck! My (first?) issue is that I want to do something similar to the following example code. Here CIRCLE is an in-memory implementation of a circle, and it is desired to create a DAO object which moves storage to a postgres backend. (We have lots of circles...) Pretend CIRCLE has a host of useful functionality attached and I can't just point all the defmethods to DAO-CIRCLE. (defclass SHAPE () ()) (defclass CIRCLE (SHAPE) (radius)) (defclass DAO-CIRCLE (CIRCLE) ((radius :col-type real)) (:metaclass dao-class)) (dao-table-definition 'dao-circle) => ERROR: Slot RADIUS in class #<DAO-CLASS DAO-CIRCLE> is both a column slot and a regular slot. Why doesn't this work, and how can I make it work? It seems like this is useful functionality to have. I want the DAO-CIRCLE's radius to be a column slot. Cheers, -Luke
