    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

    'advanced_filters',

    'semantics',
    'sites',

]

Urlpatterns

urlpatterns = [
    path('admin/', admin.site.urls),
    url(r'^advanced_filters/', include('advanced_filters.urls')), 
]

Admin

class SemanticsClusterAdmin(AdminAdvancedFiltersMixin, admin.ModelAdmin):
    raw_id_fields = ("page",)
    list_display = ["id", "detail_view", "page", "name", ]

    advanced_filter_fields = (
        'id',
        'page',
    )


    exclude = []


admin.site.register(SemanticsClusters, SemanticsClusterAdmin)

Documentation: https://github.com/modlinltd/django-advanced-filters/blob/develop/README.rst

Could you help me understand why it blows up? And how to cope with the problem?

>Solution :

After studying the documentation for Django and the Readme for Django Advance Filters. It looks like there is a typo or deprecated use of "url" in the Readme for Advance Filters

Instead of

urlpatterns = [
path('admin/', admin.site.urls),
url(r'^advanced_filters/', include('advanced_filters.urls')), 
]

Use:

urlpatterns = [
path('admin/', admin.site.urls),
re_path(r'^advanced_filters/', include('advanced_filters.urls')), 
]
