request.user returning abstract user (django-stubs)

Question

I am trying to type the following:

user: Final[CustomUser] = self.request.user

Where CustomUser is my custom user model defined in settings.py. My IDE complains that Expected type 'CustomUser', got 'AbstractBaseUser' instead. Looking at the documentation, it says that self.request.user returns an instance of AUTH_USER_MODEL however clearly this is not happening.

Also tried:

 def get(self, request: MyRequest, *args, **kwargs) -> HttpResponse:
    user: Final[CustomUser] = self.request.user

Where

from django.http import HttpRequest
from my_user_app.models import CustomUser

class MyRequest(HttpRequest):
    user: CustomUser

`request.user` returns an `AnonymousUser` for users that are not logged in. Does your `CustomUser` model subclass from `AbstractBaseUser`? — Iain Shelvington, May 10 '20 at 17:16
@IainShelvington It extends `AbstractUser`. Is that not enough ? — Bula, May 10 '20 at 17:21
Which IDE/plugin/framework are you using? I don't think Django has type annotations — Iain Shelvington, May 10 '20 at 17:43

There is an open issue regarding this error here https://github.com/typeddjango/django-stubs/issues/309

According to the docs for django-stubs you have to provide your own request type when using a custom user model. At the bottom of the page on PyPi How can I use HttpRequest with custom user model?

from django.http import HttpRequest
from my_user_app.models import CustomUser

class MyRequest(HttpRequest):
    user: CustomUser

Then you would have to use this to annotate self.request

 def get(self, request: MyRequest, *args, **kwargs) -> HttpResponse:
    user: Final[CustomUser] = request.user

Tried this but it still complains – Bula May 10 '20 at 17:56
Can you add where you have tried this to your question? – Iain Shelvington May 10 '20 at 17:57
Edited. Is this what you suggested means? – Bula May 10 '20 at 17:58
Shouldn't you use the `request` parameter passed to the method and not `self.request`? – Iain Shelvington May 10 '20 at 18:00
is self.request same as just using request there ? (because the annotations work like you've suggested now) - I'm just not sure if there are adverse effects – Bula May 10 '20 at 18:02
It's not the same as the class that your method is in has a different type for `self.request` https://github.com/typeddjango/django-stubs/blob/master/django-stubs/views/generic/base.pyi – Iain Shelvington May 10 '20 at 18:05
You need to either have a base view class that correctly annotates `request` or figure out how to override django-stubs – Iain Shelvington May 10 '20 at 18:07
