Carl,
Try the code below for plain json.
For pyjamas you can use jsonrpc it works well with web2py.
See the web2py book to learn how to use the @service annotation.
def call():
session.forget()
return service()
@service.json
def stockPrices(q):
sym = q
rows = db(db.stock_price).select()
prices = rows.find(lambda row: row.symbol in sym).as_list()
return dict(prices=prices)
then call it like:
http://127.0.0.1:8000/init/default/call/stockPrices?q=ABC
