ModuleNotFoundError: No module named 'my_app.urls' in django

Question

after deploying site on heroku,it's showing Internal server error. for debug I made "debug=true" and I found this error:
"ModuleNotFoundError: No module named 'my_app.urls' "

I've added my app in installed app list

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'my_app',
]

my_project urls:

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

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

my_app urls:

from django.urls import path
from . import views
urlpatterns = [
    path('',views.home ),
    
]

views.py:

from django.shortcuts import render

def home(request):
    return render(request,'index.html')

site running on local server while debug = true but not running while debug=false (showing server error )

so how to fix this error "ModuleNotFoundError: No module named 'my_app.urls' "

What did I miss. Any help/suggestion will be highly appreciated. Thanks

Answer 1

you have to include your app information inside of your installed app section

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'my_app.apps.YOURAPPCONFIG NAME',
]

YOURAPPCONFIG NAME is in your apps.py, and copy the name of class and paste it.
