Où dois-je placer les fichiers Sinatra destinés à être intégrés dans une application Rails3?

Question

Je veux utiliser la nouvelle fonctionnalité Rails3 qui vous permet d'intégrer une application Sinatra dans les rails.

Dans mon fichier itinéraires, je:

# app names changed to protect the (not so) innocent 
MyApp::Application.routes.draw do 
    match "/service", :to => MyService 
    ... 
end 

Et /lib/my_service.rb je

class MyService < Sinatra::Base 
    get "/" do 
    "Hello World" 
    end 
end 

Lorsque je tente de démarrer le serveur Rails je reçois Uninitialized MyService constante (NameError), que je soupçonne signifie que mon fichier Sinatra est dans le mauvais répertoire. Où suis-je censé le mettre?

J'ai trouvé une bonne réponse à cette question, grâce à this article.

je manque le tout important exige en-tête en haut de mes routes fichier:

require 'my_service.rb' 

# app names changed to protect the (not so) innocent 
MyApp::Application.routes.draw do 
    match "/service", :to => MyService 
    ... 
end
