In Rails 2.3.14 your link to is eventually calling url_for, which calls polymorphic_url (through polymorphic_path) since you're not passing it a String, Hash or the symbol :back ( https://github.com/rails/rails/blob/v2.3.14/actionpack/lib/action_view/helpers/url_helper.rb#L76). In turn that eventually calls build_named_route_call, which uses RecordIdentifier.plural_class_name(current_user), which is returning the class name ( https://github.com/rails/rails/blob/v2.3.14/actionpack/lib/action_controller/polymorphic_routes.rb#L154). And finally that in turn eventually calls current_user.model_name ( https://github.com/rails/rails/blob/v2.3.14/actionpack/lib/action_controller/record_identifier.rb#L100 )
You could look into overriding what model name returns for those classes, but that seems really far reaching and dangerous. I'd just use the path helper since that best represents what you want to do, which is send an Owner or Member object not to /owners/:id or /members/:id but to /users/:id instead; ergo the verbosity doesn't seem bad to me, it helps clarify. As an alternative, you could also define the /owners/:id and /members/:id routes and point them at UsersController; not sure if that's okay to have the extra routes, but that allows you to keep your shorthand notation, has that map to the expected URL, but lets you DRY the underlying controller class. \Peter -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
