How to use Rails URL helpers in any Ruby class
In Rails 3+, you can use:
class Project delegate :url_helpers, to: 'Rails.application.routes' def project_path url_helpers.project_path(self) end end
For Rails 2, use the attached
#url_writer, on which you can call URL helpers:
class Foo does 'write_urls' def self.class_method url_writer.session_path end def instance_method url_writer.project_path(5) end end
