ruby on rails - método no definido ''caché'' para nil: NilClass después de actualizar a los rieles 4.2.5.1

ruby-on-rails ruby-on-rails-4.2

Question

Al actualizar desde los rieles 4.2.5 a los 4.2.5.1 recientemente lanzados, me he encontrado con este error. Este error existe solo para las especificaciones con un before_filter que representa un estado no válido, como el render file: "public/422", status: :unauthorized . Me sale este error para ruby-2.2.2 y ruby-2.3.0

El error existe en el método de resolución action_view, lo que implica que el valor @cache es nil. Sin embargo, en el método de initialize se debe crear una instancia: @cache = Cache.new

Todavía estoy trabajando en una muestra reproducible, pero hasta ahora estoy perdido en cuanto a cómo @cache podría ser nulo.

Estas son las variables de configuración establecidas en mi entorno test.rb

config.cache_classes = true
config.eager_load = false

config.serve_static_files   = true
config.static_cache_control = ''public, max-age=3600''

config.consider_all_requests_local       = true
config.action_controller.perform_caching = false

config.action_dispatch.show_exceptions = false
config.action_controller.allow_forgery_protection = false  

config.action_mailer.default_url_options = {
  :host => ''127.0.0.1'',
  :port => 3000
}

config.action_mailer.delivery_method = :test
config.active_support.test_order = :random
config.active_support.deprecation = :stderr

Answer 1

Este es un problema de rspec / rspec-rails.

Puede actualizar a rspec-rails-3.4.1 para solucionarlo. A menos que haya codificado la versión de rspec-rails en su Gemfile, ejecute:

bundle update rspec-rails rspec

debe solucionar el problema.
