Bonjour,

Je suis actuellement un cours de ror. J'ai créé un projet ror, via la commande rails project sur ubuntu.
Puis, j'ai créé un controleur:

sudo script/generate controller about
exists app/controllers/
exists app/helpers/
create app/views/about
exists test/functional/
create app/controllers/about_controller.rb
create test/functional/about_controller_test.rb
create app/helpers/about_helper.rb

Lorsque je lance firefox avec l url :

http://localhost:3000/about

J'obtiens une erreur 500:

script/server
=> Booting WEBrick...
=> Rails application started on http://0.0.0.0:3000

Est que cela pourrait venir de mon ficheir route.rb:

more routes.rb
ActionController::Routing::Routes.draw do |map|
# The priority is based upon order of creation: first created -> highest prior
ity.

# Sample of regular route:
# map.connect 'products/:id', :controller => 'catalog', :action => 'view'
# Keep in mind you can assign values other than :controller and :action

# Sample of named route:
# map.purchase 'products/:id/purchase', :controller => 'catalog', :action => '
purchase'
# This route can be invoked with purchase_url(:id => product.id)

# You can have the root of your site routed by hooking up ''
# -- just remember to delete public/index.html.
# map.connect '', :controller => "welcome"

# Allow downloading Web Service WSDL as a file with an extension
# instead of a file named 'wsdl'
map.connect ':controller/service.wsdl', :action => 'wsdl'

# Install the default route as the lowest priority.
map.connect ':controller/:action/:id.:format'
map.connect ':controller/:action/:id'
end

Merci d'avance pour votre aide.
