so for me it works, when I do this :

python manage.py migrate
python manage.py makemigrations todolist
python manage.py migrate todolist
python -m webbrowser -t "http://127.0.0.1:7000/"
python manage.py runserver 7000

You just need to create your tables...

That error is usually caused by a missing database migration after creating a new model. Simply running the following commands fixes it most of the time: python3 manage.py makemigrations python3 manage.py migrate

Now you can restart your server.
