I'm primarily a Java Developer, I tried Rails recently for the first time on a project without a SQL datastore and found that it was difficult to get a foothold as a beginner. Switched to Scala Play and the more flexible framework allowed what I needed easily even without a lot of knowledge on Play. Rails seems like it would be great if your doing a typical CRUD app but if you need something a little outside that box it gets in the way. That said it seems like apps aren't always just CRUD anymore and that may be why its falling in popularity.
