Question

我正在尝试使用django活动流创建新闻源。我正在创建一个目标流，但如果它是一个不保存的注释，则不会保存操作对象

 "id": 14,
        "actor": {
            "id": 1,
            "email": "zacmwangi94@gmail.com",
            "first_name": "",
            "last_name": ""
        },
        "verb": "commented on",
        "action_object": null,
        "target": {
            "id": 6,
            "venue": {
                "id": 1,
                "name": "IMAX",
                "address": "NAIROBI",
                "city": "NAIROBI",
                "rating": "1.1"
            },
            "thumbnail": null,
            "user": 1,
            "event_pic_url": null,
            "name": "A movie",
            "time": "2017-11-11T16:02:00Z",
            "description": "A description",
            "event_type": "Movie",
            "invite_only": true,
            "free": false,
            "age_restriction": true,
            "ticket_price": 1000.0,
            "created_at": "2017-03-19T10:35:41.723753Z"
        }
    }

当动作对象是照片时，它会被正确保存。这是我的评论模型：

class Comment(models.Model):
    user = models.ForeignKey(User)
    text = models.TextField()
    content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
    object_id = models.PositiveIntegerField()
    content_object = GenericForeignKey('content_type', 'object_id')

这就是我在创建评论后创建动作的方式：

def comment_activity(sender, instance,created, **kwargs):
    if created:
       action.send(instance.user, verb='commented on', action_object=instance, target=instance.content_object)


post_save.connect(comment_activity, sender=Comment, dispatch_uid=comment_activity)

我也尝试使用action.send信号和Action.objects.create()将其保存在视图中，但所有这些方法都失败了。

  def create(self, request, *args, **kwargs):
        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            comment = Comment.objects.create(**serializer.validated_data)
            Action.objects.create(actor=comment.user,action_object=comment,verb="commented on",target=comment.content_object)
           # action.send(request.user,action_object=comment,verb="commented on",target=comment.content_object)
            return Response(
            serializer.data, status=status.HTTP_201_CREATED
            )
        return Response({
            'status': 'Bad request',
            'message': 'Comment could not be created with received data.'
        }, status=status.HTTP_400_BAD_REQUEST)

问题是否与内容类型的使用有关，如果它确实如何解决？

我尝试将FETCH_RELATIONS设置为false，但它不会改变任何内容。

需要帮助使用django-activity流保存动作对象
