I don't have time to offer specific suggestions or help, other than to
say that while persistence classes are powerful, these are wildly
advanced. I steer clear of them myself.

All,
Quick question.
I'm trying to make one of my classes persistent. The class
itself has only simple attributes of general types like
int,string,timestamp, no lists etc. It seems to work just fine
without subclassing Persistent, but causes an error when I do. Do I
always need to subclass persistent?
There error i receive seems to have a problem with my __eq__ method.
Here's the error I get when I do subclass persistent:
.......No handlers could be found for logger "ZODB.Connection"
