Hi again;
Looking at the source code I realised that form.save_m2m() must be
called.
def save_related(self, request, form, formsets, change):
form.save_m2m()
for formset in formsets:
self.save_formset(request, form, formset, change=change)
if not change:
# Generate and send report only if creating for first time
(insert)
parent_obj = form.instance
generate_pdf(parent_obj)
I think the above does what I wanted; so far so good anyway.
