Re: [Zope] deleting while iterating over ObjectManager

Is it safe to delete instances while iterating over the contents of an ObjectManager instance, as in:

for item in folder.objectValues(): if some_condition: folder.manage_delObjects(item.getId()) break do_something(item)

1. store the list beforehand, just to be sure. 2. use objectItems since it contains the (id, object) tuple you need item_list = folder.objectItems() for item in item_list: if some_condition: folder.manage_delObjects(item[0]) break do_something(item[1]) HTH, oliver
