If you’re creating a new Engine in Rails 3 (or upgrading one from Rails 2), you’re probably wondering how to do the routing. This is how:

Rails.application.routes.draw do
  namespace :admin do
    resources     :users
    resource      :session
    match         'login'  => 'admin/sessions#new', :as => 'login'
    match         'logout' => 'admin/sessions#destroy', :as => 'logout'
    root          :to => 'admin/home#index'
  end
end

Note that in Rails 3, non-resource routes (like root, login and logout above) don’t obey the namespace context when selecting the controller. This requires you to match specifically to admin/sessions rather than simply sessions.
