Navbar Partial Werfen ActionView :: Template :: Fehler Ausnahme für Benachrichtigung Gem

Question

Ich benutze die Benachrichtigung gem von Schienen-Motorhttps://github.com/rails-engine/notifications. Es scheint zu versagen, wenn ich auf die Controller-Index-Seite dafür traverse. Es behauptet, dass die Links in meiner Navigation teilweise undefiniert sind, wenn sie eindeutig sind. Der NotificationController ist der einzige, der dieses Problem gerade hat. Ich habe dieses Juwel nie vor heute benutzt. Mein Code ist unten

     post :share

     get 'like', to: 'posts#like'

    get 'users/:username' => 'users#show' 
    patch 'users/:username', to: 'users#update' 
    resources :follows, :only => [:create, :destroy]

    controller :favorites do 
    get 'favorites/index' 
    end 

    resource :user_profile, :only => [:edit, :update], path: 'profile' 
    root 'home#index' 
end 

Ich habe versucht, das Benachrichtigungsmodul einzuschließen, anstatt den Controller darin zu verpacken. Es funktioniert nicht so gut.

Answer 1

Ändern Sie Ihre Routen, wie folgend:

resource :user_dashboard, as: 'dashboard', only: :show 

Und Ihr Link sieht wie folgt aus

<%= active_link_to dashboard_path, class_active: 'nav-link active', :class_inactive => 'inactive' do %>
