urls.py в папке проекта
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('bboard/', include('bboard.urls'))
]
Вот urls.py приложения
from django.urls import path
from . import views
urlspatterns = [
path('', views.index)
]
Ошибка
django.core.exceptions.ImproperlyConfigured: The included URLconf '' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.
