Opened up my python shell to test my models. First tested my CarMake model for output

for car_make in CarMake.objects.all():
print(car_make.name, car_make.description, car_make.country)

which returns data appropriately. Then tried on my CarModel model

for car_model in CarModel.objects.all():
print(car_model.name, car_model.type, car_model.year)

which returns empty.

Also launched my app on the browser and returns an empty list.
