In my opinion the current crop of web frameworks still make it very easy to do the “bad” thing since to do PRG properly you need to think what kind of an interaction you want with users and not cop out saying its technically very difficult in <insert framework here>. If you resort to ActiveX controls, popups without navigation bars and/or weird javascript hacks to stop users from clicking refresh or back buttons then perhaps you should have written a better web application.

Whenever I play with Rails, or for that matter any other web framework, I get stuck on trying to find a problem to solve (or a set of requirements). Fortunately the Agile Development with Rails book from the Pragmatic Programmers has a nice little bookstore application that I can develop iteratively. I’ve put my latest adaptation of their depot application to use post-redirect-get (even works with ActiveResource scaffolds), UUIDs as ActiveRecord primary keys, HAML, SASS and RSpec on GitHub. Feedback is always welcome.

Easy to do in Java (with java.util.UUID) and in Python (using the uuid module). This has been a bit of a pain in Rails, until now – check out Ariejan de Vroom’s post. I especially like his solution as it plays well with RSpec, although to be picky I would have chosen UUID.random_create rather than UUID.timestamp_create.
