Question

I have a model in rails, lets say User, which i want to have a relation to another user.

User A, can be the boss of User B and User B can be the boss of User C and D.

This relation is a one-to-many. One user can stand above multiple users.

How would i do this.
My user model has currently an ID with the name boss_id, which will be nil if the user is in the top of the food chain.

My active record class looks like this:

class User < ActiveRecord::Base

  has_many :users #People beneath the user
  belongs_to :user
end

But now I want to use relation with a name. Lets say boss and followers.

How can I achieve this?

Answer 1

Here’s how it would look like:

class User < ActiveRecord::Base

    belongs_to :boss, :class_name => 'User'
    has_many :followers, :class_name => 'User', :foreign_key => :boss_id

end
