Update Django to Version 5.2 LTS

[afuetterer]

Rationale / Begründung

After updating to Django 4.2 just recently, there is already an alpha release of Django 5.0. The official release is scheduled for 2023-12-04. We could add another test case to catch breaking changes early on. Dependabot would also send us a PR in December, but it might be nice to be prepared for this update, with Django being rdmo's main dependency.

Affected

Admins, Devs

Notes

In GitHub Actions:

• add django5 matrix entry, using include
• in tests step add pip install django ~5 at the end

Django 5.0 is in beta now. It only supports Python >= 3.10.
https://docs.djangoproject.com/en/dev/releases/5.0/#python-compatibility

What does this mean for rdmo? Stick with Django 4.2 to be Python 3.8 and 3.9 compatible?

[jochenklar]

Yes please, for as long as possible.

5.2.7 is the latest version as of today.

PR is welcome? Or you want to stay with 4.2?

I would see this more as part of RDMO 3.0 (or 3.1), it is currently under development with many changes to the backend as well, probably it will take some months for the release.
However, with the end of support for 4.2 LTS in April 2026, it may be sensible to include this upgrade to Django 5.2 in the RDMO 3.0 already as well??
