Comment (by chad.lyon@…):
That work around doesn't work but is really close. I think you want to
avoid using the query set altogether when list editing because it could
possibly return different results than it did when the list to be edited
was POSTed. This actually works as a work around:
{{{
def _existing_object(self, pk):
return self.model._default_manager.get_query_set().get(pk = pk)
}}}
...but has side effects. For example, what if another user deletes one of
the items in the list to be edited? This workaround will raise
{{{DoesNotExist}}}. Django committers need to get busy on the solution
talked about in #11313 because this bug is really ugly.
