Devise und Rails - ArgumentError in Devise :: RegistrationsController # create

Question

Wenn ein neuer Benutzer ein neues Benutzerregistrierungsformular einreicht, erhalten sie die folgende Fehlermeldung. Ich vermute es, weil das devise/registrations_controller.rb nicht existiert.

Muss ich diese Ordnerstruktur und den Controller erstellen oder kann ich routes.rb ändern, um die Suche nach einem nicht vorhandenen Controller zu vermeiden?

Fehler:

ArgumentError in Devise::RegistrationsController#create 

wrong number of arguments (0 for 1) 
Rails.root: C:/Users/COMPAQ/Documents/NetBeansProjects/RailsBlog 

Parameters:

Trace zurück - ich habe einen Blick hatte, aber nicht bestimmen kann, wo Problem liegt:

Answer 1

Die Devise::RegistrationsController existiert within the Devise gem, so dass Sie es nicht erstellen müssen.

aktualisieren: Der Fehler tritt auf, weil Sie has_secure_password verwenden, die für hausgemachte Authentifizierungslösungen. Sie brauchen es nicht mit Devise (es behandelt die Verschlüsselung des Passworts selbst). Werde diese Linie los!

Der Grund, warum Ihre App explodiert, ist, dass sie password_digest als Attribut in Ihrem Modell erwartet und validates its presence. Wenn es die Validierung durchführt, versucht es das Attribut zu lesen, aber was es stattdessen erhält, ist Devices password_digest-Methode (die erwartet, das Kennwort als ein Argument zu erhalten, so löst ein ArgumentError aus, wenn es einen nicht erhält).
