Kontinuierlicher ApplicationController (alle Controller) konnte nicht automatisch geladen werden

Question

Ich habe gerade angefangen, diesen Fehler für alle Controller zu erhalten. Nicht sicher, was passiert ist, weil ich auf der Benutzeroberfläche so CSS, ERB-Dateien arbeitete und dann lade ich die Seite neu und beginne diesen Fehler zu bekommen.

Vielen Dank für Rat und Hilfe.

Controller: (app/Controller/...)

home_controller.rb 
application_controller.rb 

In home_controller:

class HomeController < ApplicationController 
    def index 
    end 
end 

In application_controller:

class ApplicationController < ActionController::Base 
    protect_from_forgery with: :exception 
end 

Routen:

Rails.application.routes.draw do 
    devise_for :admins, path: '', path_names: { sign_in: 'login', sign_out: 'logout'} 

    # HOME 
    root to: 'home#index' 

    # MESSENGER 
    match '/webhook', :controller => 'messenger', :action => 'callback', :via => :post 
    get '/webhook' => 'messenger#verify_callback' 
end 

Fehler: (für alle Regler gleiche Fehler außer konstant und Pfad)

Answer 1

Ich benutze C9 und SSH für AWS-Server .. Das Problem war in C9, weil es die Dateien nicht gut synchronisiert, so, wenn ich die Datei schließe und öffnen Sie es erneut, die Dateien waren leer.

Falls jemand C9 benutzt und das selbe Problem hat wie ich.

Answer 2

Dies ist keine Routen Problem. Das Problem ist ein Problem mit konstanter Auflösung (plus Autoloading), weil es sagt, dass es die HomeController Klasse in home_controller.rb nicht findet, trotz der Tatsache, dass es dort definiert ist.

Versuchen Sie, den Serverprozess neu zu starten. Obwohl Autoloading alle Änderungen an Klassen behandeln sollte, habe ich manchmal gesehen, dass es fehlschlägt. Ich habe auch das gleiche Problem mit dem spring Preloader passiert.

Wenn dies nicht funktioniert, können Sie uns wissen lassen, ob Sie eine IDE verwenden und was passiert, wenn Sie versuchen, mit der Klasse ApplicationController innerhalb der Konsole zu interagieren.

Answer 3

Wie Sie erwähnt, dass alle Controller diesen Fehler geben, weil einige Änderung überprüfen Sie bitte in der Datei application.rb und fügen Sie diese Zeile oder ein ähnlich wie unter

config.autoload_paths += %W(#{config.root}/controllers) 

Die oben sein kann in Ihrem application.rb Ihre bekommen diese Fehler, der es verhindert automatisches Laden aller Controller
