This is a functional example for the plugin Ajaxful Rating:
github.com/edgarjs/ajaxful-rating
To run the app (each line is a single command):
git clone git://github.com/edgarjs/ajaxful-rating_demo_app.git rake gems:install rake db:migrate script/server
And that’s all. Point your browser to localhost:3000 and see it works.
