Hi guys, Given a page that retrieves data from a 3rd party API, how would you then go about associating additional info in the application''s database with that record? Specifically, the page displays info on a product, and I''d like to store and display locally created reviews for that product. To display the product I''m using a route of the form /product/ <productid> where the productid is the barcode of the product. The barcode is used in the controller to look up the data via the 3rd party API. It''s the structure of the database / model and how to link one the other that I''m struggling with conceptually. (I''m a relatively newbie with Rails, Ruby & ActiveRecord, and programming in general (!) so please forgive me if this is painfully obvious!) Many thanks in advance for any advice or suggestions...

I''d keep it simple. Make the barcode value a uniquely-indexed attribute of your own product record (with it''s id field). Use the id field for all your rails coding - the product record and parent id of the child review records, and use the barcode value to access the external 3rd party API data. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

So: /products/<id>/reviews/<id> with <id> referencing the database id field. All fine so far. However, now I have a model-less /products/<barcode> that can display any item, for which all data is coming from the API, and for which there''s no product record, may or may not have reviews, ie. It''s possible to search for and display data for _any_ product that the API has data for, with no local database involved, hence I don''t have a product_id field to code around. That''s where I''m struggling (and probably mostly because I''m coding by example and haven''t found a suitable example to borrow from).
