Problème de routage des rails personnalisés avec 2.3.8 et Mongrel

Question

J'ai un contrôleur appelé 'Exposures' que j'ai créé automatiquement avec le script/générer un appel d'échafaudage. Les pages d'échafaudage fonctionnent bien. J'ai créé une action personnalisée appelée 'test' dans le contrôleur d'expositions. Lorsque j'essaie d'appeler la page (http://127.0.0.1:3000/exposures/test/1), j'obtiens un écran blanc et vierge, sans aucun texte dans la source. J'utilise Rails 2.3.8 et mongrel dans l'environnement de développement. Il n'y a pas d'entrées dans development.log et la console qui a été utilisé pour ouvrir bâtarde a l'erreur suivante:

lecteurs Clever remarqueront le « graphique » action. C'est ce que je veux vraiment travailler, mais si je n'arrive même pas à faire fonctionner le test, alors je suis sûr que je n'ai aucune chance.

Des idées? J'ai redémarré le bâtard quelques fois sans changement.

Answer 1

problème semble être résolu. Il y avait un petit bug dans rack:

http://github.com/rack/rack/commit/f6f3c60938ea3b08f3292a2480e6753c293584e5

J'ai changé le fichier sur mon système comme indiqué parce que je ne savais pas comment bien udpate de ce GitHub.

ruby gems update rack (?) 

Vous connaissez celui-ci?
