我有一个追随者的模型。这个模型是这样的：

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)

用户创建多种类型的对象，如帖子和问题。我希望显示关注特定用户的所有用户的所有帖子和问题。简化显示关注我的用户的所有帖子和问题。
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。它给了我下面的错误，我不明白：

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

下面是我使用的视图：

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？
