NEVER DO THAT!  Product.first does a database call.  Therefore, it 
should *never* be used in the view.  The view should never, ever touch 
the database under any circumstances.  Instead, make the database call 
in the controller and set an @instance variable.

What error?

You''ll probably need to include ActionController::UrlWriter in your 
helper.

Best,
