According to docs and testing (in the interpreter) I can make a read-only calculated attribute using property() (I know that setters do not work w/ non-new-style classes). So I tried the following:
class CMixin: def getter(self): return 'test' prop = property(getter)
and when I try to mix in this object w/ a Folder object, the instance returns <property object at 0x8b45edc> for the 'prop' attribute. Is this an issue with pickling or something else?
In Zope 2, the ExtensionClass that is the C base class used for Persistent classes, doesn't work with python 2.2 properties.
But, you can use a ComputedAttribute to get much the same effect. -- Steve Alexander
