I have the need to "update" some persistent objects in a ZODB to change their class.
One use case comparable to the one I have would be to change all objects of type Folder to OrderedFolder. To do that, I envisionned finding all thoses objects and doing
ob.__class__ = OrderedFolder ob._p_changed = 1
Would this work ?
See the thread "Renaming a product" just a few days ago. The conclusion was that this would not work.
If not, what other hack could I do ? The idea being that I don't want to recreate all the objects.
You might not have a choice. A conversion script might take a while to run and your ZODB might get a bit more bloated, but otherwise, it'll work fine. -- Paul Winkler http://www.slinkp.com Look! Up in the sky! It's ULTRA BULLET FROGMAN! (random hero from isometric.spaceninja.com)
