OK, so I've somewhat answered my own question here and gotten things figured out.
I do, however, have another question. What would be the proper/clean way to do inline editing with newforms? In the end I did some extremely hackish things to get the multiwidget/ multivaluefields to render with each item in a row being in a separate <td>. Basically I want to have tables like the following: Name AttendingEvent1 AttendingEvent2 AttendingEvent3 Name1 X X Name2 X etc.. This table is made up of model instances that are tied via foreign key to a parent group, so this means the form also ends up with items that don't belong in a tabular format. What should I be subclassing to do this? I don't want everything in each row in a single <td> or <p>, this way it's difficult to associate the fields with meaning. Might it make sense to have a different way to display fields in inline editing mode with labels in a header row, and then instances of a model showing up in the following rows? I won't post any of the hacky code I just put together because it is rather evil, and I'd like to replace it :-) It does, however, work quite well!
