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

Question

Cuando un nuevo usuario envía un nuevo formulario de registro de usuario obtiene el siguiente mensaje de error. Lo sospecho porque el dispositivo/registrations_controller.rb no existe.

¿Necesito crear esta estructura de carpetas y controlador o puedo modificar routes.rb para evitar buscar un controlador inexistente?

error:

ArgumentError in Devise::RegistrationsController#create 

wrong number of arguments (0 for 1)

Answer 1

Devise::RegistrationsController existe within the Devise gem, por lo que no necesita crearla.

actualización: El error se produce porque está utilizando has_secure_password, que es para soluciones de autenticación de fabricación casera. No lo necesita con Devise (maneja el cifrado de la contraseña). ¡Deshazte de esa línea!

La razón por la que hace que su aplicación explote es que espera que password_digest sea un atributo en su modelo, y validates its presence. Cuando realiza la validación, intenta leer el atributo, pero lo que obtiene en su lugar es el método password_digest de Devise (que espera recibir la contraseña como argumento, por lo que plantea un ArgumentError cuando no obtiene uno).
