Any chance of getting an updated version of the complex forms example that will take advantage of accepts_nested_attributes_for?
I have sent an email to the author (Ryan Bates) some times ago and got the answer:
The solution I show in that episode is out of date and I don’t recommend using it in Rails 2.3. Instead you can use the new accepts_nested_attributes_for method. I have an example online here. http://github.com/ryanb/complex-form-examples/tree/master I hope to do an episode on this feature soon.
