from external files/network endpoints. When Input instances are created, we
perform normal Django validation processing, involving
form.is_valid()/form.errors. As we know, Django 5.x does something like:

One other approach you could consider is using Django's built-in form and
model validation. You could create a custom form class that inherits from
the built-in Django `ModelForm` and override the `clean` method to perform
your tenant check.
For example:

The over-ride of save_model() achieves nothing functional but is merely an
