I use Engine. How to get access to url_helpers, such as <name>_path or _<name>_url, in a separate class? In application it simple: Rails.application.routes.url_helpers.<name>_path
But how to get access to url_helpers in Engine? When I use Rails.application.routes.url_helpers.root_path, then I get '/', root of Application. Other helpers for Engine aren't not defined. Also Rails.my_engine.routes.url_helpers.root_path fails.
