I can't seem to get around this. "request.namespace" gives me a '/'. I tried to emit using the room argument by passing in the "request.sid" but that causes the emit to not work at all. Can anyone tell what I'm doing wrong?
Isn't 'request.namespace' a string or I am missing something ? Not only it doesn't have socket method, but also you can't get a string to emit messages.
I am stucked on that too. Can't figure what version to use in order to get the right API.
I tried this and works for me:
io.emit('message', "Hello at %s" % (datetime.now()), room=clients[k])
This clients[k] is the ID of the conection... On cliente is socket.id and in the server is request.sid (This one you need to import from flask import request)
I dont tried if puttin an array in room will send to all clients in there...
@juniordnts worked perfectly, thanks!
room=self.sid
Me again. Repo owner states his plans to use the session ID as the room name:
For the upcoming major release of this extension I'm planning to automatically create the individual client rooms. These will be given the name of the session ID, which is exactly what you suggested above.
miguelgrinberg/Flask-SocketIO#89
This has now been implemented. You can access the session ID with
request.sidshort example:
# Object that represents a socket connection class Socket: def __init__(self, sid): self.sid = sid self.connected = True # Emits data to a socket's unique room def emit(self, event, data): emit(event, data, room=self.sid) @socketio.on('connect') def foo(): sockets[request.sid] = Socket(request.sid)Now you can just store the sid in a way that represents the reason you want to emit to that socket specifically.
Great response! Short and concise! Thanks for the example.

Thanks, @juniordnts.
The above code worked for me finally, and here is my code.
Hope it helps others save time.
