If you change the class of an object, you have to make sure its
container is also re-persisted, because in the ZODB the container of
a persistent object has a reference to its child that includes the
class.

Salut Jean-Marc,

I'm about to migrate a couple of documents from "documentish" to
folderish (FolderishProxyDocument)
CPS uses isinstance(ProxyFolderishDocument) in some places, so
changing
to portal type to folderish is not enough.
instances must be changed too.
the current script does:
for brain in brains:
ob = brain.getObject()
if ob is None:
continue
if isinstance(ob, ProxyFolderishDocument):
continue
ob.__class__ = ProxyFolderishDocument
ob._p_changed = 1 # trigger persistence
ob.proxyChanged()
# + some workflow history stuff omitted here
anything more to think about ?
You may need to update the workflow related annotations on the
object as
well and ensure it's compatible with the folferish workflow your
objects
are gonna follow after this migration. I guess you will need to
update
your workflow associations as well to specify a folderish workflow
instead of the former one.
Keep us posted about the result.
J.
sorry, I sent the one that didn't work. here is the correct one.
ciao.
