How can I reject and close connections in django-channels 2?

It's been 1 month since I started using django-channels and now I have a feeling that I am not disconnecting websockets properly. When I disconnect I want to destroy the group completely if no one is there and it should be no sign of existence. When I'm rejecting connections I raise channels.exceptions.DenyConnection or send {'accepted': 'False'} I was just wondering if this is the right way to do things that I've mentioned or not.

Try calling self.close()

From the channels Documentation: 

class MyConsumer(WebsocketConsumer):

    def connect(self):
        # Called on connection.
        # To accept the connection call:
        self.accept()
        # Or accept the connection and specify a chosen subprotocol.
        # A list of subprotocols specified by the connecting client
        # will be available in self.scope['subprotocols']
        self.accept("subprotocol")
        # To reject the connection, call:
        self.close()

As far as I've understood this, the way to close a group is by using group_discard.

def disconnect(self, close_code):
    async_to_sync(self.channel_layer.group_discard)("yourgroupname", self.channel_name)

Without having tested this, I would assume that raising an exception would result in an error 500 at the client. And a client receiving an error would probably interpret that not as "closed normally".

See channel docs here: https://channels.readthedocs.io/en/latest/topics/channel_layers.html#groups
