Reading back over my original question, I realized I should probably
explain the desired outcome in more detail. What I'm trying to do is simply
attach the commenting functionality to the existing product ratings. So a
customer who purchased a product can come back to the website, enter their
rating, and also enter their own personalized review. This is a different
use case than the comments themselves having ratings. The ratings and
"reviews" (comments) will belong to the product object, so that
rating_average() and rating_count() still work as expected.
Ideally this would be atomic, so a user would have to enter both a rating
and a "review" in order to save to the db.
Hope that helps clarify. Again, I'm grateful for any help/nudges in the
right direction.
