If you're trying to import your product into the interpreter, you have to load the Zope framework first. The Zope initialization is where the Persistent module is populated.

From $zopedir/lib/python:

import Zope import Products.MyProduct etc... -jfarr ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Hi! I'm a signature virus.

Hi,

I'm trying to make my own pyhton classes and use them with zope, so I tried to subclass the class Persistent. However, no matter what I try I get always an error like: *** Bobo-Exception-Value: (<class exceptions.ImportError at 80a9d98>, 'cannot import name Persistent') ***

I have read "The (old) Product API Tutorial", "Create a Boring Product in Python" and "ZODB" HowTos but I didn't find the exact way to do it. Even reading the Persistence module doesn't enlighten me too much: it's just the license and a string.

So I would appreciate if someone could give a clue about how to subclass Persistent and to which module it belong?

Oscar
