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.
# File lib/action_controller/routing/route_set.rb, line 18 def connect(path, options = {}) @set.add_route(path, options) end
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.
# File lib/action_controller/routing/route_set.rb, line 47 def namespace(name, options = {}, &block) if options[:namespace] with_options({:path_prefix => "#{options.delete(:path_prefix)}/#{name}", :name_prefix => "#{options.delete(:name_prefix)}#{name}_", :namespace => "#{options.delete(:namespace)}#{name}/" }.merge(options), &block) else with_options({:path_prefix => name, :name_prefix => "#{name}_", :namespace => "#{name}/" }.merge(options), &block) end end
Creates a named route called “root” for matching the root level request.
# File lib/action_controller/routing/route_set.rb, line 23 def root(options = {}) if options.is_a?(Symbol) if source_route = @set.named_routes.routes[options] options = source_route.defaults.merge({ :conditions => source_route.conditions }) end end named_route("root", '', options) end
