Let''s say you''re building a movie rental website. You have customers, movies, and rentals to manage. REST style urls might look like this: /customers/4 /movies/15 /rentals You''d probably also want administrators to be able to view all of the rentals done by a particular customer, and other similar details: /customers/4/rentals /movies/15/rentals /rentals/529/customers Except you can''t, at least not as far as I understand route generation. Looking at routes.rb for the example: map.resources :movies do |movies| movies.resources :rentals end map.resources :rentals do | rentals| rentals.resources :customers end map.resources :customers do |customers| customers.resources :rentals end These map blocks introduce ambiguity about what rental_url(1,5) should generate - /movies/1/rentals/5 or /customers/1/movies/5. The error message pointing this out sucks (rentals_url failed to generate from {:controller=>"rentals", :action=>"index"}, expected: {:controller=>"rentals", :action=>"index"}, diff: {}), but I digress. Instead of throwing an error in this kind of situation (which I imagine would be relatively common), why not take a named route like customer_rentals_url(1,5) or new_movie_rental_url(1)? There may be a very good reason why not, and I''m new here, so bear with me. :) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
