metodo non definito `cache 'per nil: NilClass dopo l'aggiornamento alle guide 4.2.5.1

Question

Durante l'aggiornamento da rotaie 4.2.5 allo 4.2.5.1 recentemente rilasciato, ho riscontrato questo errore. Questo errore esiste solo per le specifiche con un before_filter che esegue il rendering di uno stato non valido, ad esempio render file: "public/422", status: :unauthorized. Ottengo questo errore sia per Ruby-2.2.2 che per Ruby-2.3.0

L'errore esiste nel metodo resolver action_view, il che implica che il valore @cache è nullo. Tuttavia, nel metodo initialize dovrebbe essere istanziato: @cache = Cache.new

sto ancora lavorando su un campione riproducibili, ma sto finora perso su come @cache potrebbe essere pari a zero.

Queste sono le variabili di configurazione stabiliti nel mio ambiente 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 

dello stack:

Answer 1

Questo è un RSpec/RSpec-rails issue.

È possibile eseguire l'aggiornamento a rspec-rails-3.4.1 per risolverlo. A meno che non hard-coded la versione di RSpec-rail nel vostro Gemfile, in esecuzione:

bundle update rspec-rails rspec 

dovrebbe risolvere il problema.
