= MakeVoteable

MakeVoteable is an extension for building a user-centric voting system for Rails 3 applications.
It currently supports ActiveRecord models.

* This repository is unfortunately no longer maintained. If this library is still relevant and you want to maintain it, I am happy to hand this repository over.

== Installation

add MakeVoteable to your Gemfile

gem 'make_voteable'

afterwards execute

bundle install

generate the required migration file

rails generate make_voteable

also add +up_votes+ and +down_votes+ columns to the voter (e.g. User) and voteable (e.g. Question) model migrations

add_column :users, :up_votes, :integer, :null => false, :default => 0
add_column :users, :down_votes, :integer, :null => false, :default => 0
add_column :questions, :up_votes, :integer, :null => false, :default => 0
add_column :questions, :down_votes, :integer, :null => false, :default => 0

migrate the database

rake db:migrate

== Usage

# Specify a voteable model.
class Question < ActiveRecord::Base
make_voteable
end

# Specify a voter model.
class User < ActiveRecord::Base
make_voter
end

# Votes up the question by the user.
# If the user already voted the question up then an AlreadyVotedError is raised.
# If the same user already voted the question down then the vote is changed to an up vote.
user.up_vote(question)

# Votes the question up, but without raising an AlreadyVotedError when the user
# already voted the question up (it just ignores the vote).
user.up_vote!(question)

# Votes down the question by the user.
# If the user already voted the question down then an AlreadyVotedError is raised.
# If the same user already voted the question up then the vote is changed to an down vote.
user.down_vote(question)

# Votes the question down, but without raising an AlreadyVotedError when the user
# already voted the question down (it just ignores the vote).
user.down_vote!(question)

# Clears a already done vote by an user.
# If the user didn't vote for the question then a NotVotedError is raised.
user.unvote(question)

# Does not raise a NotVotedError if the user didn't vote for the question
# (it just ignores the unvote).
user.unvote!(question)

# The number of up votes for this question.
question.up_votes

# The number of down votes for this question.
question.down_votes

# The number of up votes the user did.
user.up_votes

# The number of down votes the user did.
user.down_votes

# up votes - down votes (may also be negative if there are more down votes than up votes)
question.votes

# Returns true if the question was voted by the user
user.voted?(question)

# Returns true if the question was up voted by the user, false otherwise
user.up_voted?(question)

# Returns true if the question was down voted by the user, false otherwise
user.down_voted?(question)

# Access votings through voter
voting = user.votings.first
voting.up_vote? # true if up vote, false if down vote

# Access votings through voteable
voting = question.votings.first
voting.up_vote? # true if up vote, false if down vote

== Testing
