Hi Icodk
I would see exactly what is being submitted by the browser. Open the 'web
developer' section in your browser and look at the 'network' traffic. When
you click your submit button, see what variables etc are being sent.
If your function is really being called, then try some print statements to
see what is being received by the function (you seem to be doing that).
Or, I guess you can also call your function directly from the lambda.
...
selectable= (lambda ids: modify_price(ids, 100)),
...
def modify_price(ids, incr):
#print ids, incr
db(db.product.id.belongs(ids)).update(
product_price=db.product.product_price + incr)
