When I try to run my website via localhost:8000 , it work well , but now , when I tryed to deploy on Heroku , this error occur. My db is build using django. Please help me ,thx!!

CodePudding user response：

From the error traceback STATIC_ROOT url isn't configured.

You need to configure the static files dir url at your django app settings.py script for example as follows: STATIC_ROOT = BASE_DIR "../your-static-dir"

After that you can add run the collect static command on Heroku heroku run python manage.py collectstatic --dry-run --noinput

Also consider checking this question's statement for more info about configuring your static & media urls. Django 301 and 403 forbidden errors on my static files in production
