undefined method `first' for :users:Symbol

Hello,

I am trying to move an existing fully functional Rails application 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' for :users:Symbol (NoMethodError)         from ./script/../config/../vendor/rails/actionpack/lib/ action_controller/routing.rb:340:in `initialize'         from ./script/../config/../vendor/rails/actionpack/lib/ action_controller/routing.rb:616:in `new'         from ./script/../config/../vendor/rails/actionpack/lib/ action_controller/routing.rb:616:in `connect'         from ./script/../config/../vendor/rails/actionpack/lib/ action_controller/routing.rb:645:in `named_route'         from ./script/../config/../vendor/rails/actionpack/lib/ action_controller/routing.rb:651:in `method_missing'         from ./script/../config/../config/routes.rb:3         from ./script/../config/../vendor/rails/actionpack/lib/ action_controller/routing.rb:625:in `draw'         from ./script/../config/../config/routes.rb:1          ... 14 levels...         from ./script/../config/../vendor/rails/activesupport/lib/ active_support/dependencies.rb:147:in `require'         from ./script/../config/../vendor/rails/railties/lib/commands/ server.rb:30         from script/server:3:in `require'         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! Amrita
