我一直在尝试将UUID 4 ID传递到特定详细信息页面的URL中。
在浏览Stackoverflow和其他网站后，以下是我到目前为止的尝试：
1.将url路径作为path('car/<uuid:id>/', views.CarDetailView.as_view(), name='car-detail'),传递
但这就产生了一个错误：调用通用细节视图CarDetailView时，必须使用URLconf中的对象pk或slug。。
因为uuid字段由字母和数字组成，所以我不能使用int。
1.所以我用了这个：
path(r"^(?P<car_model>\w+)/$", views.CarDetailView.as_view(), name='car-detail'),
它返回混乱和破碎的URL：陈列室/ % 5E（% 3FP 09 c32 f72 -5863- 49 fa-a42 a-1d0fed274c4e% 5Cw+）/$
1.然后我尝试恢复到原来的样子，但是使用了View类中的一个def_object方法。

def get_object(self):
    object = get_object_or_404(CarInstance,title=self.kwargs['car_model'])
    return object

但这会返回错误：“在/展厅/汽车/09 c32 f72 -5863- 49 fa-a42 a-1d 0 fed 274 c4 e/ '汽车型号'处出现按键错误”

型号.py

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)

查看次数.py

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

    def get_queryset(self):
         return CarInstance.objects.all()

    def get_object(self):
           object = get_object_or_404(CarInstance,title=self.kwargs['car_model'])
           return object

    def get_absolute_url(self):
            return reverse('showroom:car-detail', args=[str(self.pk)])

URL的格式应该是showroom/car/09 c32 f72 -5863- 49 fa-a42 a-1d 0 fed 274 c4 e/，这将打开特定对象的详细视图。
有什么想法吗？

更新

根据下面的答案，我将get_object重写更改为

slug_field = 'title'
    slug_url_kwarg = 'car_detail'

但是我仍然得到相同的urlconf必须用slug或int错误调用。我应该在模型中定义slugh吗？

更新2

我已经修改了urlconf，但是它引发了相同的错误。

另一项更新

感谢@ruddra的帮助，我更改了路径以匹配slug_url_kwarg = 'car_detail'它现在看起来像这样：

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

但是，现在该页引发了404错误。
