Trying to trace a circular import error in Django

Question

I understand circular import error has been asked about a lot but after going through these questions I haven\'t been able to solve my issue. When I try to run my server in Djan

Answer 1

Those habitual with CamelCased names may face the error as well.

urlpatterns has to be typed exactly as 'urlpatterns'

This will show you error -

urlPatterns = [
    path('', views.index, name='index'),

Error -

django.core.exceptions.ImproperlyConfigured: The included URLconf '<module 'polls.urls' from '...\\polls\\urls.py'>' 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.

However, fixing the CamelCase will work -

urlpatterns = [
    path('', views.index, name='index'),
]

Answer 2

In my case I was getting error because I was giving wrong path of dir containing urls. So I changed this

urlpatterns = [
    url(r'^user/', include('core.urls'))
]

to this

urlpatterns = [
    url(r'^user/', include('core.urls.api'))
]

Answer 3

After 1 hour search it appears that it's wrong speelling it should be : urlpatterns

urlpatterns = [
   path('', views.index, name="index")
]

Answer 4

This error also appears if SomeView doesn't exist in views.py and you do this:

from someapp import views

urlpatterns = [
    path('api/someurl/', views.SomeView.as_view(), name="someview"),
]

So make sure all Views you use in urls.py exist in views.py
