Rails Restful Routing and Subdomains

Question

I wondered if there were any plugins or methods which allow me to convert resource routes which allow me to place the controller name as a subdomain.

Examples:

Answer 1

This is possible without using plugins.

Given the directory structure app/controllers/portal/customers_controller.rb And I want to be able to call URL helpers prefixed with portal, i.e new_portal_customer_url. And the URL will only be accessible via http://portal.domain.com/customers. Then... use this:

constraints :subdomain => 'portal' do
  scope :module => 'portal', :as => 'portal', :subdomain => 'portal' do
    resources :customers
  end
end
