App written in CakePHP that makes it easy to rate conf talk submissions.
Talk selection committee simply rate each talk from 1 to 5 stars, but cannot edit talks.
At some point would like to refactor this, or perhaps include functionality into OpenCfp.
The export in the app contains ALL entries. Here is a SQL query to get just the overall ratings:
SELECT AVG(tr.rating) as rating, t.id, t.name, t.first_name, t.last_name, t.email, t.bio, t.location, t.talk_type, t.talk_level, t.talk_category, t.abstract, t.is_most_desired, t.other_info, t.slides, t.is_sponsor FROM talk_ratings tr LEFT JOIN talks t ON tr.talk_id = t.id GROUP BY talk_id ORDER BY rating DESC
