I agree with this thread that a good method for handling the 80% case
where the Many-to-Many just has the mapping fields would be really
useful:

Massimo, I know that you're not much into including this in SQLFORM
(since 20% of the time people wish to store extra fields in the M2M
table such as 'Quantity'), but for me this would be really useful.

I guess the implementation would end up looking something like this:
http://code.google.com/p/django-ajax-filtered-fields/
Another option is the one previously mentioned:
http://marinhobrandao.com/blog/p/ajax-many2manyfield-widget-screenshot_152/
(from
http://translate.google.com/translate?hl=en&u=http%3A%2F%2Fmarinhobrandao.com%2Fblog%2Fp%2Fajax-manytomanyfield-widget%2F&sl=pt&tl=en&swap=1)

Does anyone have samples of work they've done on this?
- ideally by extending SQLFORM (or t2.create() / t2.update()) but even
manual HTML examples would be great
- code ideal but even screenshots or a demo app to play with to se how
it should look would be useful

For me, I'm more interested in UUID links than ID ones, so an
implementation that handles that nicely would be perfect :)

Many thanks,
Fran.
