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
which needs to be Rack-compatible and request
which is either an instance of ActionDispatch::Request
or an object that responds to the host
, optional_port
, protocol
and symbolized_path_parameter
methods.
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
