rake aborted! 

el modelo de usuario se puede encontrar here Ahora, ya he comparado la fuente con el original, pero parece que me falta algo. No sé qué es

¿Alguien me puede decir por qué viene este error?

Answer 1

Añadir:

attr_accessor :password, :password_confirmation 

El tutorial a continuación, le hará ahorrar un digesto en password_digest

Answer 2

Sólo tiene que añadir has_secure_password en un archivo de modelo de usuario si no lo ha hecho todavía.

class User < ActiveRecord::Base 
attr_accessible :email, :name, :password, :password_confirmation 
has_secure_password 
# .. 
end 

Answer 3

Se produce estos errores debido a que el primer bloque de before {} está tratando de agregar dos atributos que el modelo de usuario no especifica - password y password_confirmation.

Dado que este bloque before {} se ejecuta antes de cada prueba (ese es el punto), se obtiene un error en cada prueba y todas fallan. No es que la prueba está fallando, per se, sino más bien ActiveRecord no sabe qué hacer con esos atributos y está produciendo un error antes de cada prueba es realmente incluso ejecutar:

ActiveRecord::UnknownAttributeError: 
unknown attribute: password 

como dice la respuesta de codeneko, este se soluciona simplemente avanzando en el tutorial y poniendo has_secure_password en el archivo del modelo de usuario. Esto indica ActiveRecord para aceptar los atributos password y password confirmation y pasarán todas las pruebas.

Desafortunadamente, el tutorial le dice que haga un comentario has_secure_password, por lo que utilizar la respuesta de buceo como suplente probablemente no sea una mala idea hasta que el tutorial lo haya eliminado.

Answer 4

Acabo de tener el mismo problema. Estaba haciendo esto en Cloud9.

Me di cuenta de que mis pruebas tampoco funcionaban todas.

Al actualizar mi árbol de archivos se corrigieron estos dos problemas.

no necesitaba poner: contraseña o: password_confirmation directamente en el modelo (o hacer cualquier cambio de codificación en absoluto de la clase particular

Answer 5

terminé de pasar unas horas y no podía encontrar ninguna respuesta. . Mi problema terminó siendo en la línea downcase:.

before_save { self.email = email.downcase } 

se especifica que se puede hacer esta línea de una manera diferente que hice Ver abajo

https://www.railstutorial.org/book/_single-page#sec-creating_and_authenticating_a_user

.

En el Listado 6.31, podríamos haber escrito la asignación como self.email = self.email.downcase (donde self se refiere al usuario actual), pero dentro del modelo de usuario la palabra clave self es opcional en el lado derecho: self. email = email.downcase

No lo hagas de esta manera. Me dio mensajes de error cada vez hasta que invirtió a before_save { self.email = email.downcase }

y quité: self.email = self.email.downcase

soy un novato así que no está completamente seguro de por qué esto hizo que la diferencia pero lo hizo.

Answer 6

Creo que la respuesta aceptada, para agregar attr_accessor :password, :password_confirmation para el modelo de usuario es incorrecto. Porque si has_secure_password crea esos atributos de manera virtual, eso significa que lo hace por algún motivo (seguridad). Así solución podría ser solicitar la Bcrypt donde se crea un objeto de prueba del usuario:

require 'bcrypt' 

    @user = User.new(name: 'test', password: BCrypt::Password.create("my password"), password_confirmation: 'my password') 

escribí sobre esto en este post:

Rails - Unknown attribute password

Por favor, corríjanme si estoy equivocado.
