Django's approach leads to ugly code (order_line__variant__product__name__icontains=... etc.), does not allow for explicit aliasing and breaks things like static type checking and autocomplete (PyCharm has tons of Django-specific code to get basic autocomplete to work).

I think it should be possible to use the Alechemy's query builder given that it works in GINO:
