Class based views have really helped me get rid of ugly, complex, and deeply nested form handling views. I recommend looking at the source for the form wizard views mentioned in the article as well as all the views and mixins in django.views.generic.edit. As the article mentions, their features aren't always completely documented, but the code is very easy to follow.
Yeah, I'm (the author) a giant fan of CBVs in Django. Sadly, the form wizard views, although class-based and fairly sprawling, don't seem to be very friendly to experimentation. It seems to be a pretty locked-in workflow that's horribly undocumented. Hence the post.
Django is a solid framework with tons of real-world example of that very fact. Rails is a fine framework, too, but it's in a language I don't enjoy and is, to me, no where near as elegant as Django (usually) is.
I'm also not sure I see the point is commenting on a post about a feature of a framework with, essentially "swap your entire stack over to my favorite language". Maybe you have some way to backup your statement?
