Dear list, I create a product form WMI, and have a Python to call ZSQL Method Inside methods folder. But I can call the Python Script when I am in this Zclass folder, but couldn't call it from the Instance which inherited from this Zclass. I did anything wrong ? Thanks for any reply :o) ##### Python Script in My Zclass folder # Update the data to database # id: update_to_db #request = container.REQUEST #RESPONSE = request.RESPONSE print container.absolute_url() print container['sql_Update'] return printed #### ZSQL Method in My Zclass folder # id : sql_Update #### The method just for test UPDATE tt_hold_ar SET ar_head='Permission' WHERE ar_id='0000114415' ## The result when I call update_to_db in the Zclass folder <SQL instance at 8cd88a0> ## The result when I call update_to_db from inherited instance, Zope just logout me ! ?_? <!-- Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 114, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 158, in zpublisher_exception_hook (Object: 0000114415) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 98, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: update_to_db) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: update_to_db) File /usr/lib/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 252, in __call__ (Object: update_to_db) File /usr/lib/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 283, in _bindAndExec (Object: update_to_db) File /usr/lib/zope/lib/python/Products/PythonScripts/PythonScript.py, line 291, in _exec (Object: update_to_db) (Info: ({'script': <PythonScript instance at 8d03ea0>, 'context': <TTNews instance at 8cade68>, 'container': <TTNews instance at 8cade68>, '_': <TemplateDict object at 0x8d3b970>, 'traverse_subpath': []}, (), {}, None)) File Script (Python), line 18, in update_to_db File /usr/lib/zope/lib/python/AccessControl/ZopeGuards.py, line 94, in guarded_getitem (Object: 0000114415) Unauthorized: (see above) --> Best Regard, Terry
