python manage.py rename djecommerce

usage: manage.py rename [-h] [--version] [-v {0,1,2,3}] [--settings SETTINGS] [--pythonpath PYTHONPATH] [--traceback] [--no-color] [--force-color] current [current ...] new [new ...] manage.py rename: error: the following arguments are required: new

can anyone help me with this.

Just run this:

python manage.py rename demo djecommerce

Ultimately what you're doing is referring to which name you want to change and then supplying the new name

python manage.py rename old_name new_name
