But the above code is throwing error:

yeah I got that. Can you tell me what is the way to implement it?

Well you say you've got it, but you're just not doing it.

def update
@quantity = request.parameters[:quantity]
@product = request.parameters[:productid]

you're just setting @product to a string rather than using Product.find

Ruchita, I guess you might find rails irc channel a lot more useful
than this mailing list, as it's real time.
