    <p>I've got a problem with setting up a client which connects to a "distributor" server to send certain data. The server's purpose is to get data from the client and then send that data to it's all connected clients. The server works without any issues. The main client is also supposed to work as an IRC bot. Here's a text example of how it should work like:</p> <p><em>(IRC) John: Hello there!</em></p> <p><em>1. The IRC client got the message, we need to send it to the distributor now.</em></p> <p><em>2. Distributor should get this "John: Hello there!" string and send it back to it's all connected clients.</em></p> <p><em>3. If other clients send data to the distributor, which this will broadcast to all clients, the IRC client should output at it's turn the received data to a specified channel</em></p> <p>The following code is the IRC bot client (ircbot.py):</p> <pre><code>import sys import socket import time import traceback from twisted.words.protocols import irc from twisted.internet import reactor from twisted.internet import protocol VERBOSE = True f = None class IRCBot(irc.IRCClient): def _get_nickname(self): return self.factory.nickname nickname = property(_get_nickname) def signedOn(self): self.msg("NickServ", "id &lt;password_removed&gt;") # Identify the bot time.sleep(0.1) # Wait a little... self.join(self.factory.channel) # Join channel #chantest print "Signed on as %s." % (self.nickname,) def joined(self, channel): print "Joined %s." % (channel,) def privmsg(self, user, channel, msg): name = user.split('!', 1)[0] prefix = "%s: %s" % (name, msg) print prefix if not user: return if self.nickname in msg: msg = re.compile(self.nickname + "[:,]* ?", re.I).sub('', msg) print msg else: prefix = '' if msg.startswith("!"): if name.lower() == "longdouble": self.msg(channel, "Owner command") # etc just testing stuff else: self.msg(channel, "Command") if channel == "#testchan" and name != "BotName": EchoClient().sendData('IRC:'+' '.join(map(str, [name, msg]))) # This should make the bot send chat data to the distributor server (NOT IRC server) def irc_NICK(self, prefix, params): """Called when an IRC user changes their nickname.""" old_nick = prefix.split('!')[0] new_nick = params[0] self.msg(, "%s is now known as %s" % (old_nick, new_nick)) def alterCollidedNick(self, nickname): return nickname + '1' class BotFactory(protocol.ClientFactory): protocol = IRCBot def __init__(self, channel, nickname='BotName'): self.channel = channel self.nickname = nickname def clientConnectionLost(self, connector, reason): print "Lost connection (%s), reconnecting." % (reason,) connector.connect() def clientConnectionFailed(self, connector, reason): print "Could not connect: %s" % (reason,) class EchoClient(protocol.Protocol): def connectionMade(self): pass def sendData(self, data): self.transport.write(data) def dataReceived(self, data): if VERBOSE: print "RECV:", data IRC.msg("#chantest", data) #This one should send the received data from the distributor to the IRC channel def connectionLost(self, reason): print "Connection was lost." class EchoFactory(protocol.ClientFactory): def startedConnecting(self, connector): print 'Started to connect.' def buildProtocol(self, addr): print 'Connected to the Distributor' return EchoClient() def clientConnectionFailed(self, connector, reason): print "Cannot connect to distributor! Check all settings!" reactor.stop() def clientConnectionLost(self, connector, reason): print "Distributor Lost connection!!" reactor.stop() if __name__ == "__main__": IRC = BotFactory('#chantest') reactor.connectTCP('irc.rizon.net', 6667, IRC) # Our IRC connection f = EchoFactory() reactor.connectTCP("localhost", 8000, f) # Connection to the Distributor server reactor.run() </code></pre> <p>The following code is the distributor server (distributor.py):</p> <p>(This one works fine, but maybe it could be useful for further reference)</p> <pre><code>from twisted.internet.protocol import Protocol, Factory from twisted.internet import reactor class MultiEcho(Protocol): def __init__(self, factory): self.factory = factory def connectionMade(self): print "Client connected:",self self.factory.echoers.append(self) self.factory.clients = self.factory.clients+1 #self.transport.write("Welcome to the server!

How can I call the right function from the IRCbot class to make it send the data to the distributor server and data received from the distributor server to output in the specified channel via IRC?</p> <p>Any suggestions and possible solutions are welcome. </p> <p>If I missed any other details, please let me know. </p> <p>Thank you for your time!</p>

    1. COI don't know if it is just coincidence, but the line throwing the first error in `sendData` is not correctly indented.

    2. CO@mac: I think it has nothing much to do with `sendData`, but these functions don't want to "communicate" with each other somehow, so they can send data recieved to a different server than it's "active" one

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
