Rails 3 ready.
Acts_as_rateable is a rails plugin providing a rating interface for ActiveRecord models. It is released under the MIT license. The original plugin is used on cotcot.hu for article rating, sponsored quizzes, etc.
-
Rating scores are recorded by user
-
Users can update previous ratings
-
Uses a polymorphic association to your model, so no changes to your existing models in the database are required
-
Stores computed score and number of ratings for efficient data access
-
Possibility to change range of the ratings (1..5 is default)
To install as a plugin, use:
$ rails plugin install git://github.com/josei/acts_as_rateable.git
Install the plugin, insert ‘acts_as_rateable’ into your model, then restart your application.
class Post < ActiveRecord::Base acts_as_rateable end
Now your model is extended by the plugin, you can rate it (1-#) or calculate the average rating.
@post.rate_it(4, current_user) @post.average_rating #=> 4.0 @post.average_rating_round #=> 4 @post.average_rating_percent #=> 80 @post.rated_by?(current_user) #=> true @post.rating_by(current_user) #=> 4 @post.ratings_couunt #=> 1 Post.find_top_rated #=> top rated records
Optional you can specify the highest score using the :max_rating paramter as follows. The default for :max_rating is 5.
class Comment < ActiveRecord::Base acts_as_rateable :max_rating => 10 end
