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 returns an ActionDispatch::Request instance.
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
