All type checkers other than mypy (e.g. pyright, intellij) have ignored the level of plugin support necessary to make django work well, and so they are DOA for any large existing django codebase. Unless ruff decides to support such a dynamic interface as mypy's, it'll fare no better.
There was an effort to create a typechecking plugin interface for dataclass-style transforms for python type checkers, but what was merged was so lacking that one couldn't even make something close to django-stubs with it.

We use mypy with [django-stubs](https://github.com/typeddjango/django-stubs) which works ok nowadays.
