2003-06-11 Thread Christian Scholz
Hi list! :) I am just playing around with Ape (very cool, btw :) and wondering how it can be used from the outside, e.g. not controlled by transactions. Main idea is to manually copy parts of the ZODB to the filesystem (from a product). I first tried the transaction based process, as I found it

Hi! I actually now have a (as it seems) working version of my first approach, just using _setObject() etc. which even works recursively. Has this some drawbacks except it looks a bit like a hack due to the call of commit()? I also have the deserialization working and basically it's just a

Yo, I have an error in this code fragment: - fragment -- for childObject in container.objectValues(): id=childObject.getId() childObject2=container[id] # sometimes gives a KeyError #... - /fragment -- So it means that there are contained

This is definitely possible. You probably have a faulty factory method. In Zope, construction is a two step process that looks something like def addSomething(self, id, title=''): ob = Something(id, title) self._setObject(id, ob) An ObjectManager must know the ids of its subobjects
