ActsAsLiked

Add like feature to any Active Record models through polymorphic association. Designate any models to act as a Liker or Likeable.

Add this line to your application's Gemfile:

gem 'acts_as_liked'

And then execute:

$ bundle

Run generator:

$ rails generate acts_as_liked

And don't forget to migrate your database

$ rake db:migrate

Add acts_as_likeable to any models, and its instances can be liked by other models.

class Post < ActiveRecord::Base
  acts_as_likeable
end

Add acts_as_liker to any models, and it can like instances of other models.

class User < ActiveRecord::Base
  acts_as_liker
end

It is not necessary to use both acts_as_liker and acts_as_likeable. You can simply drop in one of them into your model and you will be good to go.

Following APIs will be provided to Likeable and Liker.

Likeable

# Count the number of likes of @post
@post.like_count

# Check if @post is liked by @user
@post.liked_by?(@user)

# Create a new Like record for @user, and @post
@post.liked_by(@user)

# Destroy the Like record
@post.unliked_by(@user)

Liker

# Create a new Like record for @user, and @post
@user.like(@post)

# Destroy the Like record
@user.unlike(@post)

# Check if @user has liked @post
@user.liked?(@post)
