Rspec and Devise: Не ўдалося знайсці сапраўднае адлюстраванне для # <Карыстальніка

з дапамогай RSpec і Devise, я атрымліваю памылку адлюстравання.

  1) BusinessesController GET index sets @new_vacation
     Failure/Error: sign_in @user
     RuntimeError:
       Could not find a valid mapping for #
     # ./spec/controllers/businesses_controller_spec.rb:10:in `block (2 levels) in '

Падобна, адказ можа быць тут Тэсты RSpec з devise: не ўдалося знайсці сапраўднае адлюстраванне , але я не магу яго атрымаць.

Любыя ідэі, я сапраўды сапсаваны! Дзякуй.
