generating an acquisition wrapper from generated code
Hi all, ====Aclass.py==== class Aclass(ZSI.TCcompound.Struct): def __init__: self._attr = "Attribute" def getAttr(): return self.attr ====myTool.py==== from Aclass import Aclass from Globals import InitializeClass from OFS.SimpleItem import SimpleItem from AccessControl import ClassSecurityInfo from Products.CMFCore.utils import getToolByName, UniqueObject from Products.CMFCore import CMFCorePermissions class myTool(SimpleTool,UniqueObject): meta_type="myTool" id="myTool" def getAclass(self): inter = [base.Aclass(),] return inter Now I want to myTool.getAclass().getAttr() What's by importing myTool from unrestricted python, there's no problem. When I access the tool from a (restricted) script or ZPT, it gives me: Insufficient Privileges or AccessControl.unauthorized.Unauthorized: You are not allowed to access 'getAttr' in this context. I gather (thanks kosh@freenode#zope) that I need to wrap the objects in inter in an acquisition wrapper. But I can't inherit from SimpleItem as well as ZSI.TCcompound.Struct: File "/usr/lib/python2.3/site-packages/ZSI/TCcompound.py", line 65, in __init__ raise TypeError('pyclass must be None or a class, not <extension class ExtensionClass at f6b..> Any Suggestions? Thanks... And sorry for my bad python. This pseudocode should be an accurate representation of what I get from ZSI's wsdl2py from Amazon's Web Services 3.0 WSDL. Complex stuff, so try to not suggest something that would require I change Aclass -- been down that road already.

Aclass needs to be inherited from Acquisition.Explcitit or Implicit and and in myTool: def getAclass(self): inter = [base.Aclass().__of__(self),] return inter hope this helps maybe you need to add security declarations to your class

Thanks Bernard. Finally figured it out... Check out http://plone.org/documentation/howto/import-soap-client-object for details On Sun, Jan 16, 2005 at 11:45:48AM +0100, Bernd Dorn wrote:

this is a extension class problem
try to get the __init__ of the superclass via __dict__
instead of:
ZSI.TCcompound.Array.__init__(self,...)
use:
