error: "HttpRequest" has no attribute "query_params"

[sobolevn]

This code produces a false-positive mypy error:

class MyViewset(
    mixins.ListModelMixin,
    GenericViewSet,
):
    def get_queryset(self):
        office_id = int(self.request.query_params['office_id'])  # here
        ...

Output:

» mypy server
server/rest_app/views.py:144: error: "HttpRequest" has no attribute "query_params"
Found 1 errors in 1 files (checked 199 source files)

My wild guest is that self.request is considered to be server/rest_app/views.py:144: note: Revealed type is 'django.http.request.HttpRequest' there, not the Request provided by the drf.

This fixes the issue:

class MyViewset(
    mixins.ListModelMixin,
    GenericViewSet,
):
    request: Request

In runtime it is the same type: <rest_framework.request.Request object at 0x10ea93f90> <class 'rest_framework.request.Request'>
