I switched from Django to Cake to ROR. There isn't much difference structurally, as all of them are after all MVC architecture, but there are little subtle things which bring about the difference in feel and usability. Cake is heavily inspired from Rails but it doesn't focus much on command line as Rails does. For any common command you have which will add files, there is a command to in Rails to bring about that change and generate ALL THE RECOMMENDED files at once. These include test files, migrations, css, js, helpers etc. This makes life much much easier. Plus, ruby feels much pleasant when compared to PHP and thus, you won't regret switching to here. It'll take 2 days to be able to create a workable app. Although you'll find a new concept in Coffee script (Which is basically using ruby syntax for JavaScript), but you can easily switch back to JS if you want by removing the extension. Come over to the dark side, you'll love it.
