mm-friendable¶ ↑

A simple MongoMapper plugin to add friendship functionality to your application

v1.1 is a mongomapper 0.9.0 update to support the new plugin system if you are using mongomapper 0.8.x please use version 1.0.1 of the gem

Install the gem

gem install mm-friendable

Or add it to your Gemfile

gem 'mm-friendable'

Then add the friendable plugin to you MongoMapper::Document

class User
  include MongoMapper::Document
  plugin MongoMapper::Plugins::Friendable

  def on_add_friend(friend)
    do something when a friend is added...
  end

  def on_remove_friend(friend)
    do something when a friend is removed...
  end
end

You must implement the on_add_friend and on_remove_friend callbacks! - however they can be empty implementations

@user_1 = User.create
@user_2 = User.create

@user_1.add_friend!(@user_2)

@user_1.following_count #=> 1
@user_1.following #=> [<User>]
@user_1.following.first == @user_2 #=> true

@user_2.followers_count #=> 1
@user_2.followers #=> [<User>]
@user_2.followers.first == @user_1 #=> true

@user_1.following(@user_2) #=> true
@user_2.following(@user_1) #=> false

• Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet

• Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it

• Fork the project

• Start a feature/bugfix branch

• Commit and push until you are happy with your contribution

• Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.

• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
