But, in my case, different fields are needed at different times, so I

Cool.
So I guess we have a doc bug against the queryset API reference.
Sim, if you're still reading this, and updating stuff in the database is
what you were trying to do, then turn you computes collection of
changes into a dictionary (if it isn't one already), "d" below, and do:

Any reason why you wouldn't Django itself? I do use the ORM to
multiple projects that have no relation to web. Works very well

I'd like to clean up the cache when an updated model instance is

Let's assume that I have a model "Person", and the user can view the

collected for this webpage, so it's a costly operation and
Django is great and I've writing quite a lot with it but my projects

There's SQLAlchemy, but it's not nearly as simple as the Django ORM. However,
nobody's stopping you from using the Django ORM (or the templates) in other
projects that don't use the rest of Django. You will have to make a minimum
settings.py or make certain values available in the scope of your
