hello, again,
I have rearranged in my product now, so that I pass along dictionaries
to populate the classes and using a cmf-tool to provide the interface
for the various methods of the classes.
I am returning objects wrapped in __of__(self), ie.
class Person(Acquisition.Implicit):
def __init__(self data):
...
PersonObject = Person(data).__of__(self)
return PersonObject
If I want to pickle, store and later reuse PersonObject, I suspect that
this also creates a similar to my original one, where I wanted to store
ZODB-references in the PersonObject.
So should I, when pickling and storing the PersonObject, store
PersonObject.aq_base
rather than just PersonObject?
Thanks,
