Description

Storing ratings is a pretty common task when building web applications with a community-based focus. Ratings can have names and values associated with them. This plugin demonstrate a simple way to manage what ratings can be used and how they are persisted.

Usage

Note that this is a reference implementation and, most likely, should be modified for your own usage.

Example

  user = User.find(1)
  video = Video.find(1)

  video.ratings.create(:rater => user, :value => 'poor')
  video.ratings.average   # => 1.0

Assets

Included with the plugin are image/stylesheet assets for creating raters using css as described at www.komodomedia.com/blog/2007/01/css-star-rating-redux
