I have built real applications in rails and django, and find them to be fairly similar in philosophy and power. What would be an example of something you encountered with django that required getting creative quickly, that rails handles more routinely? For me, the trickiest thing in either ecosystem to get a handle on was probably rspec. I tried to learn it by osmosis and that was probably the wrong way to go. In the end, it's worth having a DSL for writing tests and leads to nice clean readable code. When people are trying to learn rails, I point them to Rails 3 in Action and Michael Hartl's online tutorial, but still need a better reference for learning rspec. suggestions are appreciated.
