I''m going back to your original message. The answer that you got from Craig had you changing the view, but ALL that you needed to do was fix the line in the create action to replace :product with :sfile (since the class of the object in the form is Sfile) -Rob On Jul 31, 2009, at 10:46 AM, Gabriel Bianconi wrote:> Hello.

Just another "cut and paste" effect...<br>
I agree about "Agile Development with Rails" is a great
book....<br>
...but you shoud not cut all of the examples in it...and paste them to
your application...<br>
