I happened to have an issue with PyLance in VS Code. See the line below.
from django.shortcuts import reverse
Even though you can import reverse function like this, PyLance starts complaining
"reverse" is unknown import symbol
It kept bugging me, so I have decided to open an issue on Github.
Since I was importing reverse from django.shortcuts instead of django.urls, the type stubs did not work correctly.
To correct the unpleasant situation, I was only required to change the import statement like this:
from django.urls import reverse
Thanks to Eric Traut I learned what the problem was.
It looks like you have type checking enabled and the django-stubs type stubs installed.
These stubs indicate that ObjectDoesNotExist is exported from django.core.exceptions, not from django.db.models. And reverse is exported from djago.urls, not from django.shortcuts.
If you import these symbols from the modules where they are exported, these errors will go away.
It is likely that these other modules happen to also import (and implicitly re-export) these symbols at runtime, but you shouldn't rely on this behavior because it could change as the library evolves. The type stubs should indicate the proper (intended) import locations for these symbols as intended by the library authors.
