Rails spinoffs - Jun 2006 - AJAX data grid for Rails?

Has anyone used an AJAX data grid with Rails?
I am rebuilding a copy of the venture source web site as a first ruby/ 
rails exercise.  If anyone has used a javascript data grid with  
Rails, I would appreciate sample code, or notes on your experience.   
The controller action would presumably communicate with the data grid  
component running on the browser by extracting data from a relational  
DBMS into a model, and then serializing that into XML or JSON which  
the Javascript component could import.  However, if there was a way  
of bypassing the generation of an intermediate XML | JSON  
representation, by injecting data into a rails-compatible server-side  
component that sent the entire grid component (preloaded with data  
from the rails model) as javascript to the client, that might be  
simpler.

jSON vs Component:

It depends on what you want to do with the generated grid. If you need
to munge the data to put it into a grid (i.e. dates, timespan) for
display purposes, it is sometimes handy to have the raw json object
around so that you dont have to do a whole lot of un-munging in JS to
get at the data. It also depends on where alot of your UI logic is.
rails traditionally has alot of contoller logic on the server side. I
have gone down the route of having a more structured JS application,
where I need to massage the data more, the server being fairly dumb
(i.e. outputting json from DB mostly).

Hey Thomas, I''ve been working on a grid for awhile with the hope of
creating a Rails component of it - I really want to try to use the
clientside xslt approach for it, which I think could be done with XML,
JSON, or whatever with the rowdata. Some other info about the columns
would still need to come from somewhere. Right now, I''m extrapolating
that information from a skeleton of xhtml before the first
xslt transformation. Are you interested in developing this, or were you
just mostly wondering if something already existed?
Here''s a test page for the clientside xslt (Sarissa is fast):

Here''s the grid "working" better-

I apologize for being so behind on my reply to this, but I wrote an article 
earlier this year on just this:

Hopefully you find it useful.
