Ruby Rails 튜토리얼 8.25

Question

Rails에 익숙하지 않고 Hartl 's Rails 튜토리얼에서 8.25에 도달하기 전에 테스트가 제대로되지 않는 이유를 알 수 없습니다. 다음은 오류 및 일부 코드입니다. 나는 그것이 아마도 내가 간과 할 수있는 사소한 것이라고 생각한다. 그러나 나는 그것을 여러 번 들여다 보았다. 그리고 나는 아직도 그것을 이해할 수 없다. 어떤 도움이라도 대단히 감사합니다! 또한, 나는 더 많은 코드를 추가해야하는지 알려 주시기 바랍니다

Answer 1

쿠키 Hash (HashWithIndifferentAccess, 정확하게하기)를 반환하는 방법입니다

@current_user ||= User.find_by_remember_token(:cookies[:remember_token]) 

cookies 때문에, 그것이 있어야 :

@current_user ||= User.find_by_remember_token(cookies[:remember_token])
