[Answered ]-Access django channels' consumer class variables from outside

You can get all instance with gc.get_objects so:

import gc

class ExampleConsumer(AsyncWebsocketConsumer):

    async def connect(self):
        self.id = 1
        self.foo = 'bar'
        await self.accept()


def get_inc(cls):
    return [obj for obj in gc.get_objects() if isinstance(obj, cls)]

for i in get_inc(ExampleConsumer):
    print(i.foo)
