Chapter 09 - parler TypeError when running "migrate shop"

[jesusnunezpro]

After updating models for the shop app, makemigrations runs successfully, but migrate fails with this error:

TypeError: Translatable model <class 'fake.Product'> does not appear to inherit from TranslatableModel

Found this post with a fix that works. It does require a change to the migration file 0002_translations.py

I copied the models from the git repo. Is it my environment or does this happens to everyone?

I'm running my dev environment on Windows 10. Here's my pip freeze:

I've been trying to install the latest versions to confirm these libraries are still usable.

Any pointers would be appreciated.

Thanks.
