Can't wait for Rails 2.3
So much that we’re blogging about it on Sunday evening! Our favorite feature in the upcoming Rails 2.3 (RC2 seems to be days away) are nested attributes, a unified solution to the nested model (complex) forms problem. There’s a lot of information available already on how to use them.
On Friday, DHH applied Eloy Duran’s patch which seems to be the final push towards completing this feature. It also fixed the little bug we spotted.
