Hi, I'm trying to deploy my Django website here in pythonanywhere, but got the following error:

I followed these tutorials to make the deploy: <ul> <li>https://help.pythonanywhere.com/pages/DebuggingImportError/</li> <li>https://help.pythonanywhere.com/pages/DeployExistingDjangoProject/</li> <li>https://help.pythonanywhere.com/pages/environment-variables-for-web-apps</li> <li>https://help.pythonanywhere.com/pages/DjangoStaticFiles</li> </ul>

Any help will be appreciated, thank you!

It looks like you're trying to run code that was written for one version of Django in a different version of Django. Make sure that the version of Django that you're using in your web app is the same as the one that the code was intended for.

Hi, thanks for replying so quickly! I already checked and I have installed the same Django version in both (2.2.8).

Any ideas???

Since Django 2.0 you have to provide the on_delete argument for ForeignKey and OneToOneField.

Take a look at https://docs.djangoproject.com/en/2.2/ref/models/fields/#django.db.models.ForeignKey.on_delete
