Hello,

I am trying to move an existing fully functional Rails application  
from my laptop (Running Leopard) to my Desktop (Running Debian). I  
created a new Rails application on the Debian desktop and installed  
the restful\_authentication plugin. I also changed the routes.db file  
to include maps for users and sessions. Now, when I try to start the  
WeBrick server, I get the following error:

=\> Booting WEBrick…  
./script/…/config/…/vendor/rails/actionpack/lib/action\_controller/  
routing.rb:406:in `initialize_components': undefined method`first’

from script/server:3

When I had not altered the routes.rb file, I was able to start the web  
server, but clicking on “About your application’s environment” said  
that it could not find rails/info/properties.

Could someone please help me out with these errors? I guess the first  
one is because of what I added to routes.rb. My routes.rb file is  
below:

ActionController::Routing::Routes.draw do |map|

map.resources :users  
map.resource :session

map.resource :session, :controller =\> ‘session’

map.signup ‘/signup’, :controller =\> ‘users’, :action =\> ‘new’  
map.login ‘/login’, :controller =\> ‘session’, :action =\> ‘new’  
map.logout ‘/logout’, :controller =\> ‘session’, :action =\> ‘destroy’

# The priority is based upon order of creation: first created -\>

highest priority.

# 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’  
end

Thanks a lot!
