关于twisted 框架中的疑问

from twisted.internet.protocol import Factory
from twisted.protocols.basic import LineOnlyReceiver
from twisted.internet import reactor

class Chat(LineOnlyReceiver):
    def lineReceived(self,data):
        self.factory.sendAll("%s :%s" % (self.getId(), data))

    def getId(self):
        return str(self.transport.getPeer())

    def connectionMade(self):
        print "New commectioin from",self.getId()
        self.transport.write("Welcome to the chat server , %s\n" % self.getId())
        self.factory.addClient(self)

    def connectionLost(self,reason):
        self.factory.delClient(self)

class ChatFactory(Factory):
    protocol = Chat

    def __init__(self):
        self.clients = []

    def addClient(self,newclient):
        self.clients.append(newclient)

    def delClient(self, message):
        for proto in self.clients:
            proto.transport.write(message + "\n")

reactor.listenTCP(5000, ChatFactory())
reactor.run()

以上代 *** 用为服务端运行后为什么sendAll不能正常工作，总是报错，或者哪位能帮我编个跟他配套的client
