timeline_aggregated 被关注的用户为空

Question

基本上我有这个型号：

# models.py
class Follow(Activity, models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='friends')
    target = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='followers')
    created_at = models.DateTimeField(auto_now_add=True)

    class Meta:
        unique_together = ('user', 'target', )

    def __str__(self):
        return '{0} follows {1}'.format(self.user, self.target)

    @property
    def extra_activity_data(self):
        return {'username': self.user.username}

    @classmethod
    def activity_related_models(cls):
        return ['user', 'target']

    @property
    def activity_notify(self):
        if not settings.STREAM_DISABLE_MODEL_TRACKING:
            # Another example would be following a user. You would commonly want to notify the user which is being
            # followed.
            return [feed_manager.get_notification_feed(self.target_id)]


@receiver(post_delete, sender=Follow)
def unfollow_user_feed(sender, instance, **kwargs):
    if not settings.STREAM_DISABLE_MODEL_TRACKING:
        feed_manager.unfollow_user(instance.user_id, instance.target_id)


@receiver(post_save, sender=Follow)
def follow_user_feed(sender, instance, created, **kwargs):
    if created and not settings.STREAM_DISABLE_MODEL_TRACKING:
        feed_manager.follow_user(instance.user_id, instance.target_id)

一个简单的工作流程可以是

<load gab and freddy user instances>
Follow.objects.create(user=gab, target=freddy)  # gab follows freddy

在供稿 user:freddy.id 的 GetStream 仪表板中，我看到有 2 个关注者 timeline_aggregated:gab.id 和 timeline:gab.id。

现在，如果我加载 freddy 的 timeline_aggregated:

feed_manager.get_feed('timeline_aggregated', freddy.id)
activities = self.feed.get(limit=self.page_size)['results']

它不包含 "gab follows freddy" 的引用，因此 activities 是 {}，而我希望包含它。

我错了吗？

谢谢，

Answer 1

保存关注模型后，将创建一个 activity 并将其添加到关注者的用户供稿中，并将副本发送到目标的通知供稿中（参见 Follow.activity_notify）。

根据您的示例，activity "gab follows freddy" 应该在这两个 Feed 中："user:bag" 和 "notification:freddy"。
