I do beleive new-style classes are not currently supported in Zope 2.7.x, due to issues with ExtensionClass. Zope 2.8 should do away with that issue, allowing you to use new-style classes. This, mind you, might not be applicable to you, as PluggableBrains might not be wrapped by ExtensionClass?? J.F. -----Original Message----- From: zope-bounces@zope.org [mailto:zope-bounces@zope.org]On Behalf Of Michael Ekstrand Sent: July 23, 2004 10:42 AM To: zope@zope.org Subject: [Zope] New-style classes and PluggableBrains I'm working on developing a PluggableBrains class for some SQL methods in my application in Zope 2.7.1 (running Python 2.3.3 as shipped in the Windows Zope installer), and I've got a couple quick questions. First, if my class inherits from object, does that break anything? It's also inheriting from Acquisition.Implicit and has security information (as an external method creates one and passes it off to protected code in a place or two). Second, if I have some property objects as members, will code accessing them elsewhere behave in a sane and reasonable manner? Will Zope recognize them properly? Most importantly, can I have some or all of the members that the Z SQL Method will be populating defined as properties in the class?
