Another Layer on Top of Rails
Streamlined "is a framework, on top of Rails, that allows you to quickly generate interfaces for your ActiveRecord models. It started as a way to generate Administrative backends, but has become more general purpose over time." Looks way classier than scaffolding, but it's also having a bit of code ferment right now as it switches from being a generator to being a plugin. Another one to dig in when I get the chance.
