I've a problem to have a class which inherits from zope base classes (Role.RoleManager, Acquisition.Implicit, ObjectManager.ObjectManager and Persistent) and classes from another package. As soon as a class inherits from one of the zope base class, I get an exception when I try to instantiate an object of this class. This exception is raised when I try to call the ancestor constructor:
ZNodeImpl.__init__(self, id, title) TypeError: unbound method __init__() must be called with instance as first argument
this sounds like my class doesn't inherit from ZNodeImpl but it does !! If I remove the zope base class, everything works correctly...
it seems to have some python black magic here. Anybody can explain this to me or give some pointers ?
That's weird because I've used it a number of times. For instance: class PortalContentFolder(PortalFolder, PortalContent, DefaultDublinCoreImpl): #... def __init__(self, id, title='', **kw): DefaultDublinCoreImpl.__init__(self) self.id = id self.title = title Florent -- Florent Guillaume, Nuxeo (Paris, France) +33 1 40 33 79 87 http://nuxeo.com mailto:fg@nuxeo.com
