Comment (by anonymous):
@jkocherhans: the admin-interface works fine. I´m not exactly sure if I
understand your question but I _do_ check form.is_valid(), resp.
formset.is_valid() ...
I´ve found another workaround (for my usecase):
{{{
if form.is_valid() and amount_formset.is_valid():
if len([fs_form.__getitem__('DELETE').data for fs_form in
formset.forms if fs_form.__getitem__('DELETE').data == 'on']) !=
len(formset.forms):
# save form, formsets, do stuff
else:
formset.non_form_errors = 'At least one item has to be saved.'
}}}
with this code example, the error won´t be thrown because it´s not allowed
to delete _all_ items from the formset. of course, it´d be much better to
use the formsets clean-method to perform this check (but that doesn´t
work, unfortunately).
please let me know if I can help with more details or testing.
