Voteable Mongoid

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.

Installation

Rails 3.0.x

To install the gem, add this to your Gemfile

gem 'voteable_mongoid'

After that, remember to run “bundle install”

Usage

Making Post and Comment voteable, User being the voter

post.rb

class Post
  include Mongoid::Document
  include Mongoid::Voteable

  # set points for each vote
  vote_point self, :up => +1, :down => -1

  references_many :comments
end

comment.rb

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

user.rb

class User
  include Mongoid::Document
  include Mongoid::Voter
end

Making a vote

@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)

Getting votes count and points

puts @post.votes_point
puts @post.votes_count
puts @post.up_votes_count
puts @post.down_votes_count

Getting the list of voted objects (votees) of a class

@user.votees(Post)

Undo a vote

@user.unvote(@comment)
