I have a review content type that (node) references a product content type. I'm using fivestar ratings for overall rating and specific ratings. With fivestar I can make the product the "vote target".
One of the ratings is a "yes/no" type rating where I want to show the aggregate on the product node (x% of users rated yes).
I tried to use fivestar with a "1 point" rating where 1=yes, 0=no but the problem is that 0 votes are not saved at all, therefore always resulting in a 100% result.
I could probably use a "2 point" rating and then have a custom display formatter to do the math and translate it to the correct %.
Are there any other solutions? I can't use the rate module because I already use it for "thumbs up/down" ratings.
