class relationship < activerecord::base belongs_to :follower, class_name: "user" belongs_to :followed, class_name: "user" validates :follower_id, presence: true validates :followed_id, presence: true end user.rb

rails.application.routes.draw 'users/index' 'users/show' devise_for :users member :following, :followers end end 'users/:id' => 'users#show', as: :user end relationships | migration
class createrelationships < activerecord::migration def change create_table :relationships |t| t.integer :follower_id, index: true t.integer :followed_id, index: true t.timestamps null: false end add_index :relationships, [:follower_id, :followed_id], unique: true end end
as per route.rb, don't have required route i.e. post /relationships. add route.rb:
resources :relationships
