I would like include the ability for people to rate posts on my site
from 1 to 5. I would like to then display the average rating for each
post. To compute the average each time is obviously database and cpu
intensive. I have been thinking about the best solution. I could
certainly use a cache and expire it every x minutes. However, I don’t
want to reinvent the wheel. Is there already a ROR plugin solution out
there that I don’t know about? If not, does anyone have any good links
on this subject?
Thanks for all of your time and effort on this great project.
