Zopistas, There seems to be a bug in the machinery for attribute assignement for pluggable brains with ZSQLmethods: I can use Pluggable Brains and their methods , but whenever i try to assign a value to an attribute, AttributeError is raised. i have narrowed my testcase down to the following: simplest ZSQLmethod possible : SELECT 'testBrain' AS t FROM DUAL When using the following class definition: class Test: def __init__(self): pass def __repr__(self): return "i am a pluggable brain" everything works as expected. if i do this : class Test: def __init__(self): self.teststring = "test" it raises an AttributeError Am i not supposed to use attribute assignment in brains , or is it a bug ? - i cannot seem to find much documentation on the subject.. All information appreciated :) traceback follows: Traceback (innermost last): File /usr/home/geir/zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /usr/home/geir/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/home/geir/zope/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: LockableItem) File /usr/home/geir/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/home/geir/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: te) File /usr/home/geir/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: te) File /usr/home/geir/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: te) File /usr/home/geir/zope/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: te) File /usr/home/geir/zope/lib/python/Products/PythonScripts/PythonScript.py, line 363, in _exec (Object: te) (Info: ({'script': <PythonScript instance at 8f81f60>, 'context': <Folder instance at 90c8f20>, 'container': <Folder instance at 90c8f20>, 'traverse_subpath': []}, (), {}, None)) File Script (Python), line 1, in te (Object: guarded_getitem) File /usr/home/geir/zope/lib/python/AccessControl/ZopeGuards.py, line 151, in guarded_getitem File /usr/home/geir/zope/lib/python/Shared/DC/ZRDB/Results.py, line 175, in __getitem__ File /usr/home/geir/zope/lib/python/Shared/DC/ZRDB/Results.py, line 158, in __init__ (Object: Test) File /usr/home/geir/zope/Extensions/test.py, line 5, in __init__ (Object: Test) AttributeError: (see above) -- Geir Bækholt web-developer geirh@funcom.com funcom oslo | webdev-team
