I need a field that will allow content editors to enter a rating while editing a node, with the options 'yes', 'no', 'maybe' and 'unknown'. I then want to be able to display those ratings in a view, as images (tick, cross, fence, ?). I need to be able to have more than one on each node.
I can't do this with the rate module, because it doesn't do fields (there is a rate field issue, but it's not moving very fast). Fivestar only does five-star ratings, so that's out.
Optionally, I would also like to be able to give each result a numerical value, so that I can do calculations across fields (e.g. median).
Are there any options out there that can do this kind of rating?
