Ok, I understand how to add ZClasses in both dtml and Python, thanks all. But my problem is that I need to add a nested ZClass to another ZClass. Let me explain: I have a ZClass called ProfileDirectory that extends ObjectManager. Inside ProfileDirectory, I have another ZClass called Profile. The idea is that ProfileDirectory is the folder for Profiles. Now, in zope I have added a ProfileDirectory (with id=directory) to a folder (with id=consultants) that looks like: /consultants/directory Now I need to Programatically (In a python script) add Profiles to /consultants/directory If anybody understands what I just said and can help me, I would be greatly appreative!!! I have tried the following with no luck in a python script: context.consultants.directory.manage_addProduct['Profile'].Profile_add(_.None,_,NoRedir=1) context.consultants.directory.manage_addProduct['ProfileDirectory'].Profile_add(_.None,_,NoRedir=1) context.consultants.directory.manage_addProduct['ProfileDirectory'].Profile.Profile_add(_.None,_,NoRedir=1) context.consultants.directory.manage_addProduct['ProfileDirectory']['Profile'].Profile_add(_.None,_,NoRedir=1) context.consultants.directory.manage_addProduct['ProfileDirectory'].manage_addProduct['Profile'].Profile_add(_.None,_,NoRedir=1) In all cases I get an error saying that Profile is not found.
