FakeAssociations

Enables association DSL in classes that don't inherit from ActiveRecord.

Installation

Add this line to your application's Gemfile:

gem 'fake_associations'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fake_associations

Usage

class User
  include FakeAssociations

  # Need
  attr_accessor :id
	
  has_many :tweets
  has_many :favorites
	
  has_many :friendships, foreign_key: 'follower_id'
  has_many :followed_user, through: :friendships, source: :followed
	
  has_many :reverse_friendships, foreign_key: 'followed_id', class_name: 'Friendship'
  has_many :followers, through: :reverse_friendships, source: :follower
	
  has_many :favorite_tweets, through: :favorites, source: :tweet
end

class Friendship < ActiveRecord::Base
  #  Table name: friendships
  #
  #  id          :integer  not null, primary key
  #  follower_id :integer
  #  followed_id :integer

  belongs_to :follower, class_name: 'User'
  belongs_to :followed, class_name: 'User'
end

class Tweet < ActiveRecord::Base
  #  Table name: tweets
  #
  #  id          :integer  not null, primary key
  #  user_id     :integer
end

class Favorite < ActiveRecord::Base
  #  Table name: favorites
  #
  #  id          :integer  not null, primary key
  #  user_id     :integer
  #  tweet_id    :integer

  belongs_to :post
  belongs_to :user
end

Limitation

Support associations is only has_many and limited options.

In the future, will support more association.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake false to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
