[Answer]-Using post_delete signal to delete a StreamItem

✅

In your delete_stream_item() function, instance is the object that has just been deleted, in your case either a Fe or Event instance. What you want is to retrieve all related StreamItem instances (using the instance ctype and pk) and delete them.

Warning: untested code:

def delete_stream_item(sender, instance, signal, *args, **kwargs):
    ctype = ContentType.objects.get_for_model(instance)
    StreamItem.objects.filter(content_type=ctype, object_id=instance.id).delete()
