Django has a community stubs project, are you using it?

the stubs can only do so much. There's so much magic and inferred properties that a type checker will never be able to fill in alone

Does django-stubs work with other type checkers than Pyright?

Stubs are a standard python feature (PEP 561) so I'd expect them to work with any type checker which supports stubs, which should be all of them (as much of the ecosystem is typed via stubs).
