c[3001,"Connection aborted"]

[cdvv7788]

I am trying to setup a simple flow for notifications. Something like:

class NotificationRouter(ModelPubRouter):
    route_name = 'notification-router'
    valid_verbs = ['subscribe']
    model = Notification
    serializer_class = NotificationSerializer

    def get_subscription_channels(self, **kwargs):
        return ['notification']

route_handler.register(NotificationRouter)

The serializer is just a ModelSerializer that should return the id:

class NotificationSerializer(ModelSerializer):
    class Meta:
        model = 'notifications.models.Notification'
        publish_fields = ('id', )

On javascript i am trying to subscribe, but all i am getting is c[3001,"Connection aborted"]. The subscribe() function is not even calling it's failure function. swampdragon.ready is being reached tho.

I can't find the cause of this error anywhere, and the dragon server is quite silent, which does not help either. What's your approach to debugging issues like these?

You are using ModelPubRouter and should therefore overwrite get_subscription_context and not get_subscription_channels (documentation).
