The property isn't a Django field thus there's no way to guess what type it should be.
Please note that the discussion group is the best place to take this discussion and other usage questions. Thanks!

Well yes you cannot guess it if it's on class level, but you can guess it on instance level?

>>> OrderItem.objects.last().unit_price
Decimal('78.00')
>>> OrderItem.objects.last().unit_price.__class__
<class 'decimal.Decimal'>
