mongoid_followable¶ ↑

Please refer to mongo_followable for latest version.

In console:

gem install mongoid_followable

or in Gemfile:

gem 'mongoid_followable', "~> 0.1.9"

To make model followable you need to include Mongoid::Followable into your document;Meanwhile, you also need to include Mongoid::Follower in your follower model:

class User
  include Mongoid::Document
  include Mongoid::Followable
  include Mongoid::Follower
end

class Group
  include Mongoid::Document
  include Mongoid::Followable
end

Now you can set authorization:

current_user.set_authorization('user', 'game') # now current_user cannot follow User and Game model
current_user.unset_authorization('User', 'Game')

And then you can follow a model:

@group = Group.new
@group.save

current_user.follow(@group)
current_user.unfollow(@group)

You can also judge whether a model is a follower of another model or a model is a followee of another model:

	
current_user.follower_of?(@group)
current_user.followee_of?(@group)

Moreover, it’s easy to get a model’s follower/followee count:

current_user.followers_count
current_user.followees_count

Of course, you can get a list of followers/followees:

	
User.followers_of(@group)
User.followees_of(@group)

@group.all_followers
@user.all_followees

Getting a model’s followers/followees by type is also possible:

@group.followers_by_type("user")
@user.followees_by_type("group")

And their count:

@group.followers_by_type("user")
@group.followers_count_by_type("user")
@user.followees_by_type("group")
@user.followees_count_by_type("group")

You can also get a model’s follow/followed history:

@user.ever_follow
@group.ever_followed

Another feature is to get a list of models which has the most followers/followees:

User.with_max_followees
User.with_min_followees
User.with_max_followees_by_type('group')
User.with_min_followees_by_type('group')
Group.with_max_followers
Group.with_min_followers
Group.with_max_followers_by_type('user')
Group.with_min_followers_by_type('user')

Now you can tell if two models have some common followers/followees by following methods:

@user.common_followees?(@another_user)
@user.common_followers?(@group)

And see what the common followers/followees are:

@user.common_followees_with(@another_user)
@user.common_followers_with(@group)
