Django 获取用户创建的对象，这些用户属于用户列表

我有一个模范供追随者使用.以下是模型:

class Follow(models.Model):
    followee = models.ForeignKey(User, on_delete=models.CASCADE, related_name="followee")

    follower = models.ForeignKey(User, on_delete=models.CASCADE, related_name="follower")

    created_at = models.DateTimeField(auto_now_add=True, verbose_name="created at")
    updated_at = models.DateTimeField(auto_now=True, verbose_name="updated at")

    class Meta:
        unique_together = ["followee", "follower"]

    def __str__(self):
        return "{} is following {}".format(self.follower, self.followee)

    def save(self, *args, **kwargs):
        if self.followee == self.follower:
            return "You cannot follow yourself"
        else:
            super().save(*args, **kwargs)

用户可以创建多种类型的对象，如帖子和问题.我想要显示所有用户的所有帖子和问题，跟随特定的用户.简化显示我所有的帖子和问题的用户关注我.

我正在使用一个名为drf_multiple_model的模块，这是我的视图，我无法使用它.它给出了我不理解的以下错误:

Cannot use QuerySet for "Follow": Use a QuerySet for "User".

以下是我使用的视图:

def get_followers(queryset, request, *args, **kwargs):
    id = kwargs['user']
    user = User.objects.get(id=id)
    followers = Follow.objects.all().filter(followee=user)
    return queryset.filter(user__in=followers)

class HomeView(FlatMultipleModelAPIView):
    permission_classes = [IsAuthenticated]

    def get_querylist(self):

        querylist = [ 
            {'queryset':Post.objects.all(), 'serializer_class': UserPostSerializer, 'filter_fn': get_followers, 'label':'post'},
            {'queryset':Question.objects.all(), 'serializer_class': QuestionSerializer, 'filter_fn': get_followers, 'label':'question'},
        ]
        return querylist

请问我做错了什么？
