Hi, I'm currently building several Zope products working quite well but with which I have a problem : how can I define class properties (most often defined as lists actually) and use them in my creation forms written in DTML. For example, I've tried to use: in file MyProduct.py : class MyProduct(...): MyProductProperty = [ 'item1', 'item2', 'item3' ] def getMyProductProperty(self): return MyProduct.MyProductProperty in file __init__.py : import MyProduct ... def initialize(context): context.registerClass (MyProduct.MyProduct,...) ... methods={'myproduct_property':MyProduct.MyProduct.getMyProductProperty} and finally in my DTML file : <dtml-in myproduct_property> ... </dtml-in> But when I call my creation script from the ZMI, I get an error: Traceback (innermost last): * Module ZPublisher.Publish, line 150, in publish_module * Module ZPublisher.Publish, line 114, in publish * Module Zope, line 171, in zpublisher_exception_hook * Module ZPublisher.Publish, line 98, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Shared.DC.Scripts.Bindings, line 252, in __call__ * Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec * Module App.special_dtml, line 174, in _exec * Module DocumentTemplate.DT_In, line 628, in renderwob * Module DocumentTemplate.DT_Util, line 201, in eval __traceback_info__: myproduct_property * Module <string>, line 0, in ? * Module None, line 58, in getMyProductProperty ImportError: No module named MyProduct I forgot to tell you that I use Zope-2.6.0 with Python-2.1.3, and that I didn't found any good example or documentation about this point anywhere...
