I think it has to do with the route to the pylons controller/function
from the javascript file. Is your javascript located in /public/
javascripts/? Mine is located here and my controller is in /
controllers/player.py. Can i refer to the controller/function from the
javacript file by using "/player/get_data" or must I do something
else? It seems in the YUI documentation they say to use a local URL or
local Proxy, but I would think Pylons Routes would handle this.
@jsonify seems to work fine for the output of the function if I load /
player/get_data in my browser.
