Using JWT,Unable to get user in middleware

[402test]

class Product_ViewSet(viewsets.ModelViewSet):

    serializer_class = Product_serializers
    permission_classes = (IsAuthenticated,)
    authentication_classes = (JSONWebTokenAuthentication, ) # this

    def get_queryset(self):
        return Product.objects.all()

class MultitenantMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        if request.user and not request.user.is_anonymous: # AnonymousUser
            set_current_tenant(request.user.store)
        return self.get_response(request)

because jwt authentication mechanism works in view function.

solution:

from django.utils.functional import SimpleLazyObject
from django.contrib.auth.models import AnonymousUser

from rest_framework.request import Request
from rest_framework_jwt.authentication import JSONWebTokenAuthentication

def get_user_jwt(request):
    user = None
    try:
        user_jwt = JSONWebTokenAuthentication().authenticate(Request(request))
        if user_jwt is not None:
            user = user_jwt[0]
    except:
        pass

    return user or AnonymousUser()

class MultitenantMiddleware():
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        return self.get_response(request)
    def process_view(self, request, view_func, view_args, view_kwargs):
        request.user = SimpleLazyObject(lambda: get_user_jwt(request))
        if request.user and not request.user.is_anonymous:
            set_current_tenant(request.user.store)
        print(request.user)

I just want to simply use 'set current tenant()' . But it will repeat the work, is there a better solution ? thanks.
