How to use Rails URL helpers in any Ruby class

In Rails 3+, you can use:

Copy
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 Modularity Archive trait. It will give any Ruby class a method #url_writer, on which you can call URL helpers:

Copy
class Foo does 'write_urls' def self.class_method url_writer.session_path end def instance_method url_writer.project_path(5) end end

Your development team has a full backlog of feature requests, chores and refactoring coupled with deadlines? We are familiar with that. With our "DevOps as a Service" offering, we support developer teams with infrastructure and operations expertise.
