To start with, I have seen a bit of active scaffold stuff and was very impressed with it originally already. In the meantime, rails 2 have arrived. Quite a few things have changed and I was thinking that it might have an effect on the overall picture of active scaffold also.
However, checking up on railsforum etc brought out that not much effect has gone down to active scaffold kind of plugins from rails 2.
Starting up active scaffold is really easy as they say on its website also...
try it here... www.activescaffold.com It turned out to be really simple to initialize yourself with it.
Searching a bit more I came across a few tutorials -
