ruby on rails - Error al cambiar a Rails 4.1-`method_missing '': método no definido` whitelist_attributes='' para ActiveRecord:: Base: Class(NoMethodError)

ruby-on-rails ruby-on-rails-3

Question

Al cambiar de Rails 4.0 a Rails 4.1, aparece este error:

activerecord-4.1.8/lib/active_record/dynamic_matchers.rb:26:in `method_missing'': undefined method `whitelist_attributes='' for ActiveRecord::Base:Class (NoMethodError)

No estoy usando attr_accessible o attr_protected ninguna parte de mi aplicación, así que me pregunto por qué tengo un problema.

Cuando me mudé a Rails 4.0 ya había puesto en mi application.rb:

config / application.rb:

config.active_record.whitelist_attributes = false

Estoy realmente perdido aquí, ya que la mayoría de las personas que tienen errores relacionados con el mío sugieren usar gema ''protected_attributes but I don''t want to use it as I don''t have any attr_accessible nor attr_protected`.

¿Alguna idea de dónde viene este error?

Answer 1

Puede eliminar de forma segura config.active_record.whitelist_attributes = false

Desde su archivo de configuración de la aplicación.

Y elimine todos los atributos de lista blanca en sus clases de modelo.
