module ActionController::UrlFor
Includes url_for into the host class. The class has to provide
a RouteSet by implementing the _routes method.
Otherwise, an exception will be raised.
In addition to AbstractController::UrlFor, this module
accesses the HTTP layer to define url options like the host.
In order to do so, this module requires the host class to implement
env and request, which need to be a
Rack-compatible.
class RootUrl include ActionController::UrlFor include Rails.application.routes.url_helpers delegate :env, :request, to: :controller def initialize(controller) @controller = controller @url = root_path # named route from the application. end end
