Hi, I'm trying to get some filter for my admin page on a ManyToManyField. When I add it to the list_filter of the model admin, the filtering works like a charm. But this is not what I want: I'd like to invert the results, i.e. I want that only those list entries remain that do NOT have this external key in their ManyToManyField. How can I do this? I guess I could subclass ChoicesFilterSpec and register it, but I do not really know how to invert the selection...
I hope I explained sufficiently well what I want. Thanks in advance for your help.
