Recently there has been a lot of buzz about Streamlined for Rails apps. Basically it’s smart scaffolding that understands table relationships. Again, that’s the most basic way of talking about it, but it will suffice for what we’re doing right now.
One of the things that I don’t think people understand about Streamlined is that it is designed for “back end” interfaces. The screens that only a few people see and use to administer an application. For those situations it seems to be pretty nice. I cranked out a small app in an hour and a half this morning that deals with a HABTM situation and it worked out quite well.
In other words it seems to be designed to deal with a very limited scope of a rails app. It will not solve all of your user interface problems. It will just make some of them a lot easier to deal with.
