= rankles

Rankles is a collection of ranking algorithms (technically only one at the moment) implemented in Ruby.

The idea is simple. Give Rankles some data, and it will give you a number. You probably want to sort based on this number.

Quick example:

    reddit = Rankles::Reddit.new :date => entry.published_at,

                                 :upvotes => entry.cached_upvotes_count,

                                 :downvotes => entry.cached_downvotes_count

    reddit.to_f

If you're dealing with ActiveRecord objects, you can actually assign the Rankles object to a float field, and it will handle converstion:

    class Entry < ActiveRecord::Base

      # ommitted

      def calculate_ranking

        reddit_ranking = Rankles::Reddit.new :date => entry.published_at,

                                     :upvotes => entry.cached_upvotes_count,

                                     :downvotes => entry.cached_downvotes_count

        update_attributes! :ranking => reddit_ranking

      end

    end
