Hi Collin,

save_model() happens first, then save_related() which
calls save_formset() on each formset.
It might end up being easier to save the parent model _again_, instead
of doing something before it's saved.
Thank you very much for your reply, that helped a lot!
_has_changed() / has_changed() may come in handy in your case.
https://docs.djangoproject.com/en/dev/ref/forms/fields/#has-changed
In Django 1.7, it seems that _has_changed() takes several parameters
that I had not readily available, so I eventually looked this up in the
Django 1.7 source code (django/forms/forms.py), and now instead of, for
example (probably valid Django 1.8 code):
if form.fields['birthday'].has_changed(): ...
with Django 1.7 I use:
if "birthday" in form.changed_data: ...
which works very well!
Thanks again for your help!
:-)
Best regards,
Carsten
