Mongoid::Followit Build Status Code Climate Test Coverage

Add social capabilities to your models.

Prerequisites

  • Ruby >= 2.1
  • Mongoid >= 4.0

Installation

Add this line to your application's Gemfile:

gem 'mongoid_followit'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mongoid_followit

Usage

Take as an example the following model:

  class Person
    include Mongoid::Document

    field :name, type: String
  end

When including the module Mongoid::Followit::Follower

The model starts working like this:

=> jedi = Profile.create(name: 'Jedi')
=> padawan = Profile.create(name: '')
=> person = Person.create(name: 'Obi Wan')
=> person.follow(jedi, padawan)
=> person.unfollow(padawan)
=> person.followees

The model to be followed MUST include the Mongoid::Followit::Followee module

  class Profile
    include Mongoid::Document
    include Mongoid::Followit::Followee

    field :name, type: String
  end

And the followee model starts working like this:

=> jedi.followers

Callbacks

Every model that includes Mongoid::Followit::Follower can define callbacks for the #follow and #unfollow methods:

  class MyModel
    include Mongoid::Document
    include Mongoid::Followit::Follower

    before_follow   :do_something_before
    before_unfollow :do_otherthing_before

    after_follow   :do_something_after
    after_unfollow :do_otherthing_after
  end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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.
