[Django]-Trying to trace a circular import error in Django

for those who have the same error but still hasn’t debugged their code, also check how you typed “urlpatterns”

having it mistyped or with dash/underscore will result to the same error

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'),
]

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

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

In my case, I got this error because I called the reverse function for a url that required a slug parameter without placing the correct parameter in it.

Once I fixed the reverse function, it was resolved.

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'))
]

In my case i was getting this error because i was typing urlpatterns in urls.py to urlpattern.

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

In my case, I was getting

/SLMS_APP1/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.

I made a typo in ‘urlpatter’

urlpatter = [
path(”,views.index, name=’index’),

]

where in correct spelling has to be ‘urlpatterns’

urlpatterns = [
path(”,views.profile, name=’profile’),

]

this error basically occurs when you have, include the app in the main urls.py file and haven’t declared urlpattern= [] in-app file.

In my case I changed "reverse" for "reverse_lazy" on my success_url and magially it works.

I changed this…

app_name='users'
urlpatterns=(
    path('signup/', SignupView.as_view(),name='signup')
)

to this…

app_name='users'
urlpatterns=(
    path('signup/', SignupView.as_view(),name='signup'),
)

notice the last COMMA
