Describe the bug?

I am trying to reproduce the examples given in the description. With a books/views.py like this,

...
class BookListView(ListBreadcrumbMixin, ListView):
    model = Books
...

a books/urls.py like this,

...
urlpatterns = [
    ...
    path("", BookListView.as_view(), name=BookListView.list_view_name),
    ]
...

and an urls.py:

...
urlpatterns = [
    path('books/', include('books.urls')),
    ]
...

I get an error message: NoReverseMatch at /books/ 'books' is not a registered namespace

Reversing the inherited classes in books/views.py,

...
class BookListView(ListView, ListBreadcrumbMixin):
    model = Books
...

fixes the error. However, the code doesn't produce any breadcrumbs.

Apologies, but I am not getting any further. I need some help.

To Reproduce

create empty django project
create app 'books'
write "urls.py", "books/urls.py", "books/views.py", "templates/books/base.html", "templates/books/app_list.html" ... according to example code in description.

What OS are you seeing the problem on?

Ubuntu

Expected behavior?

I would like to see breadcrumbs.
