Voteable Mongoid allows you to make your Mongoid::Document objects voteable (up or down)
For instance, in a Q&A site, a user can vote up (or down) on a post or a comment.
When user provided enough information, voteable_mongoid will use only one update-in-place operation per collection.
To install the gem, add this to your Gemfile
After that, remember to run “bundle install”
class Post include Mongoid::Document include Mongoid::Voteable # set points for each vote vote_point self, :up => +1, :down => -1 references_many :comments end
require 'post' class Comment include Mongoid::Document include Mongoid::Voteable referenced_in :post vote_point self, :up => +1, :down => -3 # each vote on a comment can affect votes count and point of the related post as well vote_point Post, :up => +2, :down => -1 end
class User include Mongoid::Document include Mongoid::Voter end
@user.vote(@post, :up) # is equivalent to @post.vote(:voter_id => @user.id, :value => :up) # this will affect @post.votes_count and @post.votes_point as well @user.vote(@comment, :down)
puts @post.votes_point puts @post.votes_count puts @post.up_votes_count puts @post.down_votes_count
