Django is open-source, so you can read the source and find out by yourself why your code doesn't work as expected (I just did, and took me about 2 minutes). FWIW, you want to have a look at how Manager.none is implemented (in / django/db/manager.py) HTH. -- You received this message because you are subscribed to the Google Groups "Django users" group.
