Hey! There are a few things cleanup to be done before you continue working on these. Would you mind to address the feedback first, so it will be much easier for review.

In short:

• don't leave random commented code here and there
• no need to comment obvious things
• please install pre-commit
• please rebase on master
• remove docker-compose.override.local.yml changes

General comment:

• there are still archeological treasures from the initial development, please make sure you remove these and push them
• merge all the tests in one test_teams.py file
• the views can be a bit more django-rest-framework-like (DRF) , e.g. you can use RetrieveUpdateDestroyAPIView or similar for the views baseclasses for "teams" and "team members". This will greatly reduce your codebase and simplify maintainence.

1. cleanup the initial comments in this PR and push all the changes.
2. rebase to the latest master and push
3. run pre-commit and push
4. address most of the requests not related the the views.py or tests
5. try to automate views behavior with DRF
6. continue with tests
