Mapper instances are used to build routes. The object passed to the draw block in config/routes.rb is a Mapper instance.
Mapper instances have relatively few instance methods, in order to avoid clashes with named routes.
Create an unnamed route with the provided path and options. See ActionController::Routing for an introduction to routes.

Enables the use of resources in a module by setting the name_prefix, path_prefix, and namespace for the model. Example:
map.namespace(:admin) do |admin|
admin.resources :products,
:has_many => [ :tags, :images, :variants ]
end
This will create admin_products_url pointing to "admin/products", which will look for an Admin::ProductsController. It‘ll also create admin_product_tags_url pointing to "admin/products/#{product_id}/tags", which will look for Admin::TagsController.
