TypeError (superclass mismatch for class SessionsController)

Question

I do authorization through "login" and because of this there is such an error:

Started POST "/auth/sign_in" for 10.12.4.5 at 2018-08-07 10:20:55 +0500

Have you tried class Overrides::SessionsController? It looks like it should be namespaced. — jvillian

Actually the error message says what needs to be done:

Unable to autoload constant Overrides::SessionsController, expected /home/admin/Рабочий стол/demo/backend/app/controllers/overrides/sessions_controller.rb to define it)

Rails expects app/controllers/overrides/sessions_controller.rb to define Overrides::SessionsController, but can't find it.

Change your controller class definition to:

class Overrides::SessionsController < DeviseTokenAuth::ApplicationController
  ...
end
