GetStream(Django) - 无法丰富通知Feed

我正在使用GetStream Django包与getstream.io进行交互.我已经成功使用Enricher()该类来丰富我的活动源与Django模型信息feed_manager.get_user_feed(),但无法得到类似的结果feed_manager.get_notification_feed()

这是我的模型的缩短版本.

class Task(models.Model, Activity):
    title = models.CharField()
    assigned_to = models.ForeignKey(User)
    created_at = models.DateTimeField(auto_now_add=True)
    created_by = models.ForeignKey(User)

    @property
    def activity_object_attr(self):
        return self
    @property
    def activity_actor_attr(self):
        return self.assigned_to
    @property
    def activity_notify(self):
        return [feed_manager.get_notification_feed(self.assigned_to.id),]

如果我的视图抓取用户Feed:

enricher = Enrich()
feed = feed_manager.get_user_feed(request.user.id)
# feed = feed_manager.get_notification_feed(request.user.id)
activities = feed.get(limit=25)['results']
enriched_activities = enricher.enrich_activities(activities)

我的输出按预期工作,并且每个输出都填充了我的模板中的正确数据:

Actor: {{ activity.actor }}

Title: {{ activity.title }}

Time: {{ activity.time|timesince }}

但是,如果我切换到通知订阅源(请注意注释行外的更改):

enricher = Enrich()
# feed = feed_manager.get_user_feed(request.user.id)
feed = feed_manager.get_notification_feed(request.user.id)
activities = feed.get(limit=25)['results']
enriched_activities = enricher.enrich_activities(activities)

然后,我可以从中获取数据的唯一字段是activity.created_at.

输出activity.keys显示如下:

[u'activities', u'group', u'activity_count', u'created_at', u'updated_at', u'actor_count', u'verb', u'is_seen', u'id', u'is_read']

似乎对于通知提要,演员和对象不会被报告回GetStream:

但是,它是针对用户提要的:

我很难过为什么.我错过了什么？

好的......所以我弄清楚了我的错误.我一直在假设这notification_feed是一个扁平的饲料.哎呀,糟透了.它实际上是聚合的.因此,我能够修复如下:

代替:

activities = enricher.enrich_activities(activities)

我用了:

enriched_activities = enricher.enrich_aggregated_activities(activities)

然后,在我的基本模板中:

{% for enriched_activity in enriched_activities %}
    {% render_activity enriched_activity %}
{% endfor %}

在/activity/aggregated/task.html中查找

{% for activity in enriched_activity.activities %}
    {% render_activity activity %}
{% endfor %}

最后在/activity/task.html里面,我看到了这些项目的预期输出.

Actor: {{ activity.actor.first_name }}

Title: {{ activity.object.title }}

Time: {{ activity.time|timesince }}
