✅

You don’t need to override get_object() method. You can simply use slug_url_kwarg and slug_field. Like this:

class CarDetailView(generic.DetailView):
    model = CarInstance
    template_name = 'car_detail'
    slug_field = 'title'
    slug_url_kwarg = 'car_model'

More information can be found in get_object() documentation.

Although this is too late.However, someone could find it helpful.You can modify your modules as below:

Your models.py:

import uuid as uuid_lib
class CarInstance(models.Model):
    manufacturer = models.ForeignKey('Manufacturer', on_delete=models.SET_NULL, null=True)
    car_model = models.CharField('Model', max_length=50, null=True)
    uuid = models.UUIDField(
        db_index=True,
        default=uuid_lib.uuid4,
        editable=False, 
        unique=True,)

urls.py:

path('car/<uuid:uuid>/', views.CarDetailView.as_view(), name='car-detail'),

Lastly your views.py:

class CarDetailView(generic.DetailView):
    model = CarInstance
    template_name = 'car_detail'
    slug_field = 'uuid'
    slug_url_kwarg = 'uuid'

  1. Create get_absolute_url() in models.py:
def get_absolute_url(self):
    return reverse('car-detail', args=[str(self.<yourUUIDFieldName>)]) # self.car_model
  1. Set URL in urls.py:
urlpatterns = [
    path('car/<uuid:yourUUIDFieldName>/', # 'car:<uuid:car_model'>
    views.CarDetailView.as_view(), name='car-detail'),
]
  1. Try to change the views:
class CarDetailView(DetailView):
    model = CarInstance
    slug_field = '<uuid:yourUUIDFieldName>' # -> 'car_model'
    slug_url_kwarg = '<uuid:yourUUIDFieldName>' # -> 'car_model'
    template_name = 'car_detail.html'
  1. In addition try this if you like:
import uuid
car_model = models.UUIDField(default=uuid.uuid4, unique=True)

Replace yourUUIDFieldName with car_model check if this works,
in my way, i have no idea, i’m just a beginner like others, hope u get something out of it
