Overview

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
