Topic: Anyone else following along reading Head First into Rails?

Hi I have a quick question - in the Making Connections chapter 6, pp230-231,  the author introduces partials. The new_seat code from the 'seats' view is copied into the partial '_new_seat.html.erb' under the 'flights' folder. The scaffold code bears no resemblance to that outlined in the book, instead using a "render :partial=>form" inline command. 

Is this way form views are generated in Rails 3? In the _form partial, there is some additional error checking generated by the scaffold in addition to the input fields.

Just curious!
