AttributeError: 'WebSocket' object has no attribute 'socket'

[no13bus]

my flask version is 0.10.
When I type gunicorn -k flask_sockets.worker chat:app, there is an error:
AttributeError: 'WebSocket' object has no attribute 'socket'
why?

@no13bus Can you show the code that throws that error?

I just ran into this as well.

This code is from:
https://github.com/heroku-examples/python-websockets-chat/blob/master/chat.py

@sockets.route('/receive')
def outbox(ws):
    """Sends outgoing chat messages, via `ChatBackend`."""
    chats.register(ws)

    while ws.socket is not None:
        # Context switch while `ChatBackend.start` is running in the background.
        gevent.sleep()

The issue does not occur if you downgrade gevent-websocket to version 0.3.6 as discussed here:

https://bitbucket.org/Jeffrey/gevent-websocket/issue/50/errors-with-version-092-and-flask-sockets

However, the last solution provided in that discussion to work with the recent version of gevent-websocket did not work for me.

Hope this helps someone.

It looks like the websocket api changed. An websocket object has no longer a socket attribute, but a boolean closed that should indicate if the websocket is open or not.

@jcipriano What happens if you use the solution with while not ws.closed:?

EDIT: Changed with not ws.closed to while not ws.closed

Thanks @syntonym, that worked for me.

@syntonym while not ws.closed:

[syntonym]

@ondrae You are of course correct. Thanks! BTW: This issue can probably be closed?

[kennethreitz]

while not ws.closed is indeed proper. I've updated the code in the example chat app repository to feature the new usage. Sorry for the confusion!
