@pomegranited Updated this PR. I think we are ready to review here!

Hi @rpenido this is looking really good!

I've suggested two really minor changes, but this is ready for upstream review once they're addressed.

👍

• I tested this by running the dev server:

  # Run migrations
  python3 manage.py migrate
  # Create a superuser
  python3 manage.py createsuperuser # and used the shell to create non-superusers
  # Run the dev server
  python3 manage.py runserver
  # Login using Django Admin (non-staff users can login, they just can't see Django Admin)
  # http://127.0.0.1:8000/admin/
  # REST API is here:
  # http://127.0.0.1:8000/tagging/rest_api/v1/
  

• I read through the code
• I checked for accessibility issues N/A
• Includes documentation
• Commit structure follows OEP-0051

Thanks for applying those changes @rpenido ! This is ready for @ormsbee and/or @bradenmacdonald 's review now.

From a quick look, this looks fine. Just had two questions. I don't need to review this again; @pomegranited can give final approval and merge.

[rpenido]

@pomegranited I made the changes with new commits: 2ccae75 and cec362d. That way, I think it is easier to review.

Let me know if I should squash the commits, or you can do it yourself.

Thank you!
