This gem is thread safe.

Usage

Include the Mongoid::Likeable module into your models you want to like.

class Story
  include Mongoid::Document
  include Mongoid::Likeable

  # ...
end

You can then like by simply using the like method on the model.

@story.like @user   # @user likes @story
@story.unlike @user # @user doesn't like @story anymore

You also have access to a helpful method.

@story.liked? @user # true if @user likes @story

Like count is stored in a field called likes, so you can sort models by that field.

Note if your users are not stored in a Mongo collection or the ID field is not called _id you can still pass the ID in as the second parameter instead.

@story.like @user.id

@story.liked? @user.id
