“Rails” is still at the point that it blows my mind, but it was amazing to watch this guy create a complicated Ajax DHTML form application in 5 minutes!
How simple? Watch this video (20 MB) to see for yourself—I convert an existing form on my latest project Elements into an Ajax form in under five minutes. No view duplication. No XML, no DOM. And for common tasks like observing changes to fields and invoking CRUD actions, it’s entirely possible to avoid writing any Javascript at all! Point the helper methods to an element ID and that element’s innerHTML will be set to the remote result.
Hey, how about that? OS X.
