Question

I’m working on a project that has almost the same user relations as Twitter. User can be a fan of another user (following) and a user has many fans (followers).

How can I write this using Mongoid and Rails 3.1?

Is it enough with the User model?

class User
  inc...
  inc...

  has_many :following, class_name: 'User'
  has_many :followers, class_name: 'User'

end

Anyone done this before? I found some old posts about this issue but they were old and outdated.

Answer 1

has_and_belongs_to_many :followers, :class_name => 'User', :inverse_of => :following
has_and_belongs_to_many :following, :class_name => 'User', :inverse_of => :followers
