Actually, there would be a real advantage to doing update in the DB rather than instantiating the model, changing it, and saving it, since sql update is a single transaction. If that's what queryset update does, then the only issue with your version is that you needed two asterisks, passing "some_dictionary" as keyword arguments. (We know from the error message that update doesn't take any positional arguments beyond self, but it could take keyword arguments.)
The trouble is that I don't see update as a documented queryset method at: http://docs.djangoproject.com/en/1.1/ref/models/querysets/#ref-models-querysets So I'd have to look at the code to see what it does. Also, if it's undocumented, it should probably be considered internal and subject to change. If you're seeing it documented somewhere, I'd appreciate a url. I guess that I could go look at the code, but I've got a sneaking suspicion that that it's a worker method used in the implementation of filter, exclude, etc. So, the only way that I know to run a SQL UPDATE is with custom SQL. (I'm pretty sure that you can't do it with extra().)
