Thanks Matt, Your observations are exactly what I was running into. Good to know I should focus on class instance variables. Inheritance is a bit of mixed bag- I want it for all subclasses of my models whose superclass is not AR::Base.
The link is very helpful, wish I would have seen it earlier. A couple followups- can you comment on whether some of the approach therein has been replaced with the use of 'class_attribute'? Also, do you forsee any issues with using a Concern rather than the extend approach described there? At present I've fallen back to just extending individual models (this in retrospect might be safer in the long run, albeit not as magikal).
