[ANN] New rails plugin: acts_as_rated

I just released on RubyForge (http://acts-as-rated.rubyforge.org) a
new rails plugin for rating ActiveRecord objects. Though there are two
other plugins with similar functionality, they didn’t provide
everything I wanted, so I rolled my own.

The main difference from the other plugins is the ability to store the
statistics of the rating for each object (total/count/average) in the
model itself or in an external statistics table. This eliminates the
need to issue count/sum/avg calls on the ratings table itself, making
it a lot faster to display, and especially to search for objects by
rating.

The plugin has lots of configuration options, include all needed
methods to include in migrations, and has a very extensive test suite.
The migration has methods for creating the ratings table, the rating
statistics table and to add extra fields to the model that we want to
add ratings to. Whichever way is chosen, the plugin will adjust itself
accordingly.

Usage example:

class Book < ActiveRecord::Base
acts_as_rated
end

u = User.find_by_name “guy”
b = Book.find “Catch 22”
b.rate 5, u
u = User.find_by_name “john”
b.rate 3, u

b.rating_average # => 4
Book.find_by_rating 2…3 # => [<Book:“Catch 22”>]

b.find_rated_by User.find_by_name(“guy”) # => [<Book:“Catch 22”>]

Bye,

Guy N.
