I need to remove an attribute from most any object in my zodb. I suspect that I will need to do partial commits to not slow down the process to much.
Has anybody got an example?
Have a look at how the catalog_object function in ZCatalog.py uses subtransactions.
It was actually quite simple, except that Zope plays a trick. The key to the problem is that "get_transaction()" by magic is a "built in" function in Zope. Also in external methods. It kind of fazed me that I could not see where get_transaction() was imported from. Well it wasn't :-s so I just did something like: i = 1 transaction = get_transaction() for obj in aLotOfObjects: update(obj) if not i % 200: transaction.commit(1) # partial transaction i += 1 regards Max M "Skeptic Effect" or the "Randi Effect" When a skeptic is near, supernatural effects seem to disappear.
