[Zope] Class property in object creation form

5 Dec 2002

      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 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...

Thanks for any help,

  Thierry
