<p>I'm trying to work the Redis Cookbook example:</p> <pre><code>var http = require('http'), io = require('socket.io') fs = require('fs'), redis = require('redis'), rc = redis.createClient(9189, "pike.redistogo.com"); rc.auth("passwd", function() { console.log("Connected! to redistogo!");}); rc.on("connect", function() { rc.subscribe("chat"); console.log("rc connect event"); }); </code></pre> <p>I am successful through here but never get "message."</p> <pre><code>rc.on("message", function (channel, message) { console.log("Sending: " + message); socketio.sockets.emit('message', message); }); webpage = http.createServer(function(req, res){ console.log('webpage request starting...'); fs.readFile('./index.htm', function(error, content) { if (error) { res.writeHead(500); res.end(); } else { res.writeHead(200, { 'Content-Type': 'text/html' }); res.end(content, 'utf-8'); } }); }); webpage.listen(7777); </code></pre> <p>my client side index.htm is this</p> <pre><code><!docttype html> <html lang="en"> <head> <script src ="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"> </script> <script src="http://www.heaphash.com:7777/socket.io/socket.io.js"></script> <script> var socket = io.connect('www.heaphash.com', { port: 7777}); socket.on('message', function(data){ var li = new Element('li').insert(data); $('messages').insert({top: li}); } </script> <meta charset="utf-8"> <title>Chat with Redis</title> </head> <body> <ul id="messages">  </ul> <form id="chatform" action=""> <input id="chattext" type="text" value="" /> <input type="submit" value="Send" /> </form> <script> $('#chatform').submit(function(){ socket.emit('message', $('chattext').val()); $('chattext').val(""); //cleanup the field return false; }); </script> </body> </html> </code></pre> <p>how does a client publish to a specific Redis "chat" channel.</p>

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.
