django The STATICFILES_DIRS setting should not contain the STATIC_ROOT setting

Question

I'm deploying a Django application on heroku.

In my settings module, I have configured to host static files like

STATIC_ROOT = os.path.join(BASE_DIR, 'static_my_project')
STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static_my_project')
]
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'static_cdn', 'media_root')

and urls.py

urlpatterns = urlpatterns + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns = urlpatterns + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

But on deployment to heroku, it gives error as

SystemCheckError: System check identified some issues:
ERRORS:
?: (staticfiles.E002) The STATICFILES_DIRS setting should not contain the STATIC_ROOT setting.

Solution

may be help this.

STATIC_URL = '/static/'
    if not DEBUG:
        STATIC_ROOT = ''
    STATICFILES_DIRS = [
        os.path.join(BASE_DIR, 'static/'),
    ]

if the static root is the same with static_dirs, no need to set it in your settings. STATICFILES_DIRS is the list of folders where Django will search for additional static files, in addition to each static folder of each app installed. STATIC_ROOT is the folder where every static files will be stored after a manage.py collectstatic
