Hi there,

I am working on a module which will generate YUI widgets.

For now, I am using the YUI DataTable, which takes YUI Datasource as  
source to  
populate an html table. I wonder if someone has tried to populate a  
YUI Datasource  
with JSON generated by a rails controller? (So to dynamicly updating a  
table, with a model  
represented in JSON format).

Thanks, Christophe

Perhaps YUI4Rails does this?

Hi, it’s using JSON inside the library, but I doesn’t seem to be able  
to query a server and get JSON back, which then populates the  
widgets.
