Hi Zope,
I've been using pluggable brains in some zSQL classes. I have some
questions!
a) It seems if I initialize a variable in the __init__ method that
variable, say self.callCount = 1 is not retained across calls, eg
#python mod
res = context.sql.brainySQL()
for rec in res:
For ZSQL Methods it is possible to bind a ZClass to the records.
These can be selected from te combo box labeled 'ZClass' in the
'advanced' tab of the SQLMethod's management screen,
but there is always listed just one ZClass.
My question:
Why is there just one ZClass selectable, even if
I already found the answer myself:
one can only use ZClasses as pluggable brains that are NOT
persistent!!

You wrap via the "Advanced Tab" of a Z SQL method.

Is there a place where pluggable brains mechanism is described ?
I am beginning a Zope site project. With the few I have read
about pluggable brains, I feel that more info could help me in
deciding which part of data has to stay in ZODB and which should
go inside RDBM.
Thanks.

I forgot where I saw a description.
But it is incredibly simple:
You can wrap an arbitrary class instance around your database rows.
This transforms your rows into full featured objects with
