class Meta:
    verbose_name_plural = 'Car Records'

I output my objects using


but there are no property field added to it



The internal behavior of the Django ORM is to return fields on values() It does not include property as they are not fields that map database rows fields(column names). However, if you want all fields then just call all() or first()

Cars.objects.all() or .first()

all() is used to get all objects of the model and first() is used to get the first object from all of the objects of the model at DB level.
