A couple conversations I had at DjangoCon last week reminded me that I’d never gotten around to finishing this little post.
Since I started taking my first iOS development baby steps last year, I’ve become quite dependent on breakpoints and stepping as part of my Objective-C debugging workflow. …And yet, in Python/Django — the stack I spend most of my time working with — I’d stuck to the poor habit of throwing print statements around any found exceptions — for example, to figure out what lies in request.POST for a Django view.

While other Web frameworks can make similar claims, Django's unique asset is its built-in administration application — the admin. The admin provides advanced Create-Read-Update-Delete (CRUD) functionality out of the box, eliminating hours of repetitive work. This is key for many Web applications in development, when programmers can quickly explore their database models, and in deployment, when nontechnical end users can use the admin to add and edit site content. In the real world, there's always some customization to be performed.
