I haven't been able to find any documentation about this, but would be happy to be pointed in the right direction.
When you use null=True in a field, and then use that model in the admin, it will not save NULL to the database, but will instead save an empty string (or attempt to). I think this is broken behaviour: NULL values are semantically different to empty strings, and in certain cases (I think it was IPAddressField, but I will have another look later), it would fail to write to the database. Is there a reason that the admin interface saves what should be a NULL value as an empty string? Do I report this as a bug?
