I agree with Fred and adding overhead to view helpers is generally not good. There is also another problem with doing that. The example you chose happens to have only one method mapped to the URI pattern. This frequently isn't the case. For example, suppose you have the following in your routes.db file: resources :products That's going to generate four routes for product_path, all having the url '/products/:id(.:format)'. product_path/method:GET maps to one action. product_path/method:PATCH maps to a different action, and so on (the other two are PUT and DELETE). If you do as you suggest and have the following statement: <%= link_to "my example", product_path(1) %> There would be no way the program could assign a method from the routes.db file since it would have four to choose from. mike -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
