ERROR:tornado.general:WebSocket ... DoesNotExist: TodoList matching query does not exist.

[Nasjoe]

Hi !
I followed the first tutorial at : http://swampdragon.net/tutorial/part-1-here-be-dragons-and-thats-a-good-thing/

I changed a few lines like the {% static %} within the template as you indicate in another issue.

I work with Docker. I had to open ports 9999 and 6379 and run like this :

sudo docker run --rm -ti -p 8000:8000 -p 6379:6379 -p 9999:9999 --name swarmdragon --net host -v /DJANGO_PATH/:/swarmdragon swarmdragon bash

(can't acces to localhost:9999 from host without "-net host" option. Don't know why :/ )

When the docker container start, I have to start these process :

• service redis-server start
• ./manage.py runsd
• ./manage.py runserver 0.0.0.0:8000

And everything seems to work in the host machine but :

• I have to refresh when i add the first "TodoList object" to see it, but all the new "TodoItem object" appear well when i add, without refresh (that's the point ^^)
• I don't see another "TodoList object" if I add it in the admin panel. Even if I refresh.
• I get a strange error in the console from "./manage.py runsd" when I delete all the "TodoList object" and refresh the page. Same when i add a new "TodoList object" when I create a new one after the delete :

Django version : 1.8.6
Swampdragon just installed with pip

Did you know where this comes and how to correct ?
Many thanks,
