Mongoid::Voteable¶ ↑

Dead simple voting functionality for Mongoid models

Add to Gemfile:

gem 'mongoid_voteable'

Include the module in models where you want it:

class Post
  include Mongoid::Document
  include Mongoid::Voteable
  ...
end

You can vote by passing an integer and a voter model to the “vote” method:

@post = Post.first
@user = User.where(:name => 'Bill') # or more likely, current_user

@post.vote 1, @user     # I like this!
@post.vote -1, @user    # I don't like this!

Votes don’t have to be up or down, they can include emphasis:

@post.vote 5, @user     # I LOVE this!
@post.vote -10, @user   # Delete it from the Interwebs

You’ll often want to know if a user can vote. Simple:

@post.voted? @user      # True if they've voted

You can also get a tally of the number of votes cast:

@post.vote_count        # Just one so far!

You can get the average vote:

@post.vote_average      # votes / voters.count
