I've never done it, but now that you say it, it makes a lot of sense. Using Django just to manage the database and do migrations, even behind other language stacks.
You also get the Django admin interface for free.
I once tried using SqlAlchemy but I couldn't help asking myself why it felt so complicated compared to Django.
Running your API in Rust/Go/etc and then doing the admin and migrations via Django is a hidden superpower. I’ve said this on HN in the past few years.
People who hate ORMs have just never tried Django :D
Or Laravel's Eloquent
