Different url path than pk in Django Generic View

Question

I am using DetailView to display a template with the information about my object from my model. I used int:pk as the path for my object, but now I want to access the view from something like detail/XX-ABC (where XX-ABC stands for a unique field from my model). I didn't find a way to pass this slug and display the object.

path(r'detail/<int:pk>/', views.DetailClientsView.as_view(template_name='clients/clients_details.html',
                                                           context_object_name='client'),name='details_client'),

And this is my View.

class DetailClientsView(DetailView, UpdateView):
model = Clients
form_class = InspectionForm
def get_success_url(self):
    return reverse('search:search')

You can specify a slug in the url named slug:

path(
    'detail/<slug:slug>/',
    views.DetailClientsView.as_view(
        template_name='clients/clients_details.html',
        context_object_name='client'
    ),
    name='details_client'
),

or you can give it another name, for example:

path(
    'detail/<slug:client_slug>/',
    views.DetailClientsView.as_view(
        template_name='clients/clients_details.html',
        context_object_name='client'
    ),
    name='details_client'
),

and specify the slug_url_kwarg parameter [Django-doc] in the view:

class DetailClientsView(UpdateView):
    model = Clients
    slug_url_kwarg = 'client_slug'

    # …

In case the name of the SlugField in your model is not slug, you can set the slug_field attribute [Django-doc]:

class DetailClientsView(UpdateView):
    model = Clients
    slug_url_kwarg = 'client_slug'
    slug_field = 'slugfield_from_model'

    # …

You normally do not have to use a DetailView, since the UpdateView will pass the object to the template as well. You thus can probably implement this as a "pure" UpdateView.
