Create activity optionally based on instance attribute values












0















I have a model as following:



class UserMoodLog(TimeStampedModel, Activity):
user = models.ForeignKey('users.User', on_delete=models.CASCADE)
is_happy = models.BooleanField(_("is happy"), default=False)


I want to create activity associated to this model on it's creation only when is_happy=True. I tried overriding create_activity() and call super create_activity() only when is_happy=True but a activity must be returned from that, otherwise this line



https://github.com/GetStream/stream-django/blob/9f5fccec6cd127c73138b0170ab0b43b3798a41a/stream_django/managers.py#L64



result = feed.add_activity(activity) 


will throw error, as activity is None (because when is_happy=False I am not calling super create_activity() and thus None is returned by overridden create_activity())



Can someone please point me towards the right direction ?
