django.core.exceptions.ImproperlyConfigured: error is coming

Question

I am new to Django and hence don't have much idea about it. I am trying to create an app having the following contents in my view.py file:

from django.shortcuts import render
from fusioncharts.models import City

def pie_chart(request):
    labels = []
    data = []

    queryset = City.objects.order_by('-population')[:3]
    for city in queryset:
        labels.append(city.name)
        data.append(city.population)

    return render(request, 'pie_chart.html', {
        'labels': labels,
        'data': data,
    })

The content of my urls.py file inside the app is as follows:

from django.urls import path
from fusioncharts import views

urlpatterns = [
    path('pie-chart/', views.pie_chart, name='pie-chart'),
]

and the content of my urls.py file inside the main project folder is as follows:

from django.contrib import admin
from django.urls import path

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('fusioncharts.urls'))
]

In the settings.py file, I have added the following:

ROOT_URLCONF = 'Piechart.urls'

and under the TEMPLATES, added the following:

'DIRS': ['Piechart/fusioncharts/templates'], 

Now while running my app, I am getting the following error:

django.core.exceptions.ImproperlyConfigured: The included URLconf 'Piechart.urls' 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.

Can anyone please say what's going wrong?

Answer 1

you forgot to import include in the project urls.py, i was about to comment this but can't in my current reputation level.

from django.urls import path,include
