sorry for being so annoying with this issue, but I´m asking this one
more time.
- with using inlineformset_factory, my problem is that limiting the
choices to the currently logged-in user seems impossible. I´ve just
tried to write a custom manger with "use_for_related_fields = True",
but it´s also not possible to limit the basic queryset to the current
user.
so - before going back to pure forms and re-writing the main part of
my application, I´m just asking this question for the last time ...
thanks,
patrick
