I'm wondering on how I can access a UpdateView by using a uuid as slug. So my goal is an URL like

http://myapp.example.de/edit/7efdbb03-bdcf-4b8a-85dd-eb96ac9954fd

I have defined the the view like this:

class DeviceEventUploadView(UpdateView):

    model = Event
    slug_url_kwarg = 'uuid_slug'
    slug_field = 'unique_id' 

and urls.py like this:

urlpatterns = [
    path('admin/', admin.site.urls),
    path('edit/<uuid:uuid_slug>',
        DeviceEventUploadView.as_view(),
        name='event_update'),
]

Here I'm getting:

Using the URLconf defined in myproject.urls, Django tried these URL patterns, in this order:

    admin/
    ^edit/<uuid:uuid_slug> [name='event_update']

The current path, edit/7efdbb03-bdcf-4b8a-85dd-eb96ac9954fd/, didn’t match any of these.

Where is my failure in thinking?
