[Catalyst] Catalyst::Helper::Controller::Scaffold::REST and corresponding ajax Class::DBI-like module

[Scotty Allen]

Hi all,

I've been doing some AJAX work with Catalyst recently, and realized I
wanted the ability to push the power of Class::DBI and Catalyst all the
way to the logical edge of my application, the browser.  Thus, I've put
together two modules to address this.

The first, Catalyst::Helper::Controller::Scaffold::REST provides a
simple REST interface for a CDBI class.  HTTP GET, POST, PUT, and DELETE
on a url endpoint are mapped onto retrieve, update, insert and delete in
the CDBI class.

You can download it at:
http://scottyallen.com/perl/Catalyst-Helper-Controller-Scaffold- 
REST-0.02.tar.gz

I've held out on uploading to CPAN until I got a bit of feedback,
particularly as this will be my first CPAN release.

Also, I've put together a nifty little javascript library, which
provides a Class::DBI-like AJAX interface to the REST interface.  It's
meant to dovetail with the REST scaffolding above.  You can do things
like:

// Basic class setup
Music.Artist = Class.create();
Music.Artist.extend(JSDBI);
Music.Artist.prototype = (new JSDBI()).extend( {
     initialize: function () {
     },
});

Music.Artist.fields(['artistid', 'name']);
Music.Artist.url('http://someserver/rest/artist');
Music.Artist.elementTag('artist'); //optional

// In the calling code

var artist = Music.Artist.insert({name: 'Billy'});
var artistid = artist.id();

artist = Music.Artist.retrieve(artistid);
document.write("name: "+artist.name());

artist.name('Fred');
artist.update();

artist.destroy();

It can be found at http://scottyallen.com/code/jsdbi.js

Feedback on either module would be more than welcome.
