You can certainly write complex applications in Rails that go beyond CRUD. But in my experience (which may be outdated, I haven't written Rails in years), it requires a lot of discipline and going beyond what Rails itself offers. Sometimes you may even have to fight some of Rails's conventions. There are some people who have tried to abstract such things into yet another framework on top of Rails, e.g. I recall Trailblazer[0], but I have no idea if anyone still uses it.
