Undefined method `first' for :users:Symbol


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…
routing.rb:406:in initialize_components': undefined methodfirst’

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

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 =>


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’

Thanks a lot!
