I'm pretty new to databases and googles app engine, and I'm having a hard time getting saved data and averaging it. So basically we have a comments and ratings system where they can type comments and add ratings, but I can't figure out how to get all the ratings, and average them. I just simply do not know how to do it.
Is there any way I can pull saved data and average? So say "rating" is in database, and there were 5 ratings currently. How would I get all ratings, add them together, and divide by the number of ratings. Is this even possible? Sorry if this is confusing. - Thanks in advance -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
