Hello,

i try to follow this video  
[http://www.illanti.com/files/locomotive101.mov](http://www.illanti.com/files/locomotive101.mov)

After change my routes  
routes.db  
ActionController::Routing::Routes.draw do |map|

# Add your own custom routes here.

# The priority is based upon order of creation: first created →

highest priority.

# Here’s a sample route:

# map.connect ‘products/:id’, :controller =\> ‘catalog’, :action =\>

‘view’

# Keep in mind you can assign values other than :controller and :action

# You can have the root of your site routed by hooking up ‘’

# – just remember to delete public/index.html.

map.connect ‘’, :controller =\> ‘notes’

# 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’  
end

and deleted index.html. I launch my browser

[http://localhost:3000/](http://localhost:3000/)

i have this error message  
NameError in #

uninitialized constant NoteController  
RAILS\_ROOT:  
/Users/bolomichelin/Documents/Creation\_Perso/Developement/monApp/public/…/config/…

Does your note\_controller.rb have an “index” method? If it calls the  
list action (as scaffoling generates), is your views/note/list.rhtml in  
place? If not and you defined an index action of your own, do you have a  
matching view?

If none of this sheds any light, try changing your route so that it  
calls not just the controller but also a specific action that you know  
works.

What is the name of your controller ?  
Did [http://localhost:3000/notes](http://localhost:3000/notes) was ok ?  
the name in the the route.rb must be the same as the controller you  
want to map. In this case , you must have a notes\_controller.rb
