Re: WANTED: Demonstration of good FK & M2M form creation
You could do this pretty easily using your own forms ( not NewForms
and not Add/Change Manipulators ) along with the Django DB objects.
It's pretty easy to do a CustomChangeManipulator with fields from two
tables if it's just a one to one relationship, but for M2M, I usually
either roll my own or I display a list of the rentals with an 'edit'
link next to each item in the list.

The real answer is that there's no real promise we can make here. We're all volunteers and most of us have lives of some extent or another. If you really wanted to do something now, grab formsets.py from the newforms-admin branch and start playing with (and extending, if necessary) that. Then when it is merged into trunk, you'll already have a start, even if you have to customise your code.

Is this patience measured in days and short weeks, or in long weeks turning to months? I need to decide whether I do it all by hand right-this-moment, or delay until I can use the new newforms capabilities...

It sounds like you want the django.newforms.formsets capability that
isn't on trunk yet. There is an initial implementation in the
newforms-admin branch because they need it to implement edit-inline
equivalence in the new admin stuff, but it hasn't been completed yet
(based on the FIXMEs at the end of the file), so it isn't worth
committing it to trunk anyway.
A little more patience will be required.

Malcolm
