I'm using Django 2.0.3 on Ubuntu 16.04. Any idea what would cause a model
formset to return None when calling save()? Here is the relevant code:
RepairFormSet = modelformset_factory(Repair, form=RepairForm, exclude=[])
form = RepairFormSet(request.POST)
if form.is_valid():
form.save()
return render(request, 'message-loggedin', {
'title': 'Success',
'message': 'A repair request has been made successfully.'
})
else:
return render(request, 'message-loggedin', {
'title': 'Error',
'message': format_html(str(form.errors))
})
I checked the database and nothing is added to it, form.save() just always
returns None. When I try to debug within django/forms/models.py it seems that
form.has_changed() always returns False, causing nothing to be saved. However I
do not understand why it thinks nothing has been changed. Any help would be
greatly appreciated.
