Thank you, that's very helpful.
Do I understand correctly that the REST component uses 2 different data structures? schemas.py for the incoming JSON and serializers.py for the return data?
Yes, according to the way I did it. You could put DRF serializers and Pydantic schema into the same file and call that "serializers.py", or you could just use DRF for incoming form validation.
Similarly, you could collapse "selectors.py" into "services.py". I put read-only operations into "selectors.py" and write operations into "services.py", but you don't have to. I got that idea from this styleguide: https://github.com/HackSoftware/Django-Styleguide which is in the Appendix of the Django Domain API docs.
