The "view" in Django isn't the View in Model-View-Controller (MVC). The V is more like the template, which, you're correct, should not have business logic in it.
As a simple (very simple, please don't jump on me) analogy from MVC to Django, the M does correspond to the database models, the C corresponds to the view functions (in that the views are used to pull stuff from the database and package them for the templates or to get information from web forms and send it to the database), and the V corresponds to the template, properly initialized and populated by view functions. So, while you shouldn't stick business login in Views, it's okay to stick it in views, because they're really more like part of the Controllers. Todd P.S. When I started that, I thought I would be explicating, not obfuscating, something. Now, I'm not sure. On Wed, 2006-12-27 at 17:44 -0800, Jason C. Leach wrote:
Hi: Specifically, I'm curious how you do it without putting SQL in the view. From what I understand about the methodology of MVC this should not be done. J.
