如何将 django.contrib.auth.models.AnonymousUser 修复为用户

Question

大家好，我正在制作电子商务网站项目，我尝试将用户与购物车相关联，但我遇到了 is_authenticated() 方法的问题，当用户登录时它可以工作，但它是注销时显示此错误 "ValueError: Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x0000018AD88052B0>>": "cart.user" must be a "User" instance""

model.py
    def new_or_get(self, request):
        cart_id = request.session.get("cart_id", None)
        qs = self.get_queryset().filter(id=cart_id)
        if qs.count() == 1:
            new_obj = False
            cart_obj = qs.first()
            if request.user.is_authenticated() and cart_obj.user is None:
                cart_obj.user = request.user
                cart_obj.save()
        else:
            cart_obj = cart.objects.new(user=request.user)
            new_obj = True
            request.session['cart_id'] = cart_obj.id
        return cart_obj, new_obj

我希望工作。
