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
