Salut Im obtenir une erreur de base qui est vraiment standard je suppose en Ruby, mais ne sais pas quoi en faire. J'ai un programme que j'ai écrit. Son but est d'inscrire les invités à un camping. Vous avez un menu avec 5 options différentes. 1. Checkin. Quand je fais cela, j'obtiens une méthode non définie generateParkingLot' for #<Camping:0x10030a768> (NoMethodError) When I choose Checkout I get a undefined local variable or method départ 'pour Menu: Class (NameError). Donc, s'il vous plaît je quelqu'un a la moindre idée de mon problème ce serait génial. Je vais coller ici tout mon code. Le code est séparé dans différents fichiers et j'ai utilisé require pour les différents fichiers. Ici, bien que je vais coller tout le code dans une trace. Merci pour toute aide.Aide! check_in ': méthode non définie `push' pour nil: NilClass (NoMethodError)
