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.

Installation

has_ratings requires additional database tables to work. You can generate a migration for these tables like so:

script/generate has_ratings

Then simply migrate your database:

rake db:migrate

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
