You started a plain Python shell with the command "python". You should have used "python manage.py shell" instead, as was introduced in Part 2 of the tutorial: Now, let’s hop into the interactive Python shell and play around with the > free API Django gives you. To invoke the Python shell, use this command: $ python manage.py shell We’re using this instead of simply typing “python”, because manage.py sets > the DJANGO_SETTINGS_MODULE environment variable, which gives Django the > Python import path to your mysite/settings.py file. > See https://docs.djangoproject.com/en/2.0/intro/tutorial02/#playing-with-the-api Hope that helps, Daniel On Wed, May 9, 2018 at 5:13 PM, James Farris <[email protected]> wrote: > Instead of giving the answer, I suggest looking at the Traceback section > you posted below because the answer is there.
