error: "HttpRequest" has no attribute "user"

[snoepkast]

Hi there,

I have the following code:

class MyView(RedirectView):
    def get_redirect_url(self, *args: Any, **kwargs: Any) -> Optional(str):
        if self.request.user.is_authenticated():
            do_something_with_user()

Which results in:

$ mypy
> api/users/authentication/views.py:28: error: "HttpRequest" has no attribute "user"

Which is probably because the HttpRequest class doesn't really have the user but it is almost always added through the authentication middleware (either User or AnonymousUser).

So how do I fix this?

It would be great to have a general solution for this -- Django has several things which are added by middleware (the other one which immediately springs to mind is the session attribute).

I don't know if it makes sense to do, but I tried changing my request type to WSGIRequest, which subclasses HTTPRequest and adds a user attribute (as AbstractUser).
It silenced the error at least....

It could be added as a plugin, like, "if some AuthenticationMiddleware", add user to some HttpRequest". We need some way to describe this fact in the middleware class.
