I'm probably misunderstanding something, but surely business logic is the province of your application, and not of Django itself. Furthermore, in the general case, business logic is too complex to be implemented simply in the database layer - significant business logic would need stored procedures, triggers etc. which are inherently non- portable across RDBMS platforms. Also, in some scenarios, business logic encompasses things which are not easily embeddable in the database layer (e.g. sending out notification emails in a workflow process). While Django is more focused on a model-driven approach from which it works out and executes the SQL you need, there's no reason you can't just use the urls and views part of Django and use e.g. DB- API directly and provide complex business logic via code called from your views. If you are using Django models, the model managers seem to be the right place to put this kind of logic. Although Django does not yet provide all the hooks that are desirable for some business needs - (e.g. support for views and stored procedures and schema migration, a more generic authorization scheme) it looks as if there is work in various branches towards providing more functionality in at least some of these areas.
