    <p>At the moment I have a websocket server that generates a uuid for every connection made to it and passes that onto the client, and on the client side I update a simple list with all the connections. I'd like to see the original connaction's list refreshed, let me illustrate what I mean:</p> <ol> <li>open a tab - the first client connects and I see my uuid on the list</li> <li>I open a new tab, connect to the websocket, I see the previously connected ID and the new ID</li> <li>Now, when I go back to tab 1, I don't see both connections, only the first one that was there. How can I refresh this list, in a way such that if a websocket connection made, this list of uuid's is refreshed for all the connected clients.</li> </ol> <p>My code at the moment is the following:</p> <p>server:</p> <pre><code>var http = require("http"), io = require("socket.io"), uuid = require ("node-uuid"); var connectedPlayers = new Array(); var server = http.createServer(function(req, res) { // Send HTML headers and message res.writeHead(200,{ "Content-Type": "text/html" }); res.end("&lt;h1&gt;Server is ready &amp; listening&lt;/h1&gt;"); }); server.listen(1222, "1.1.1.1"); var socket = io.listen(server); socket.set('log level', 0); socket.on("connection", function(client) { client.on("connection", function(){ console.log("Client connected."); }); client.on("disconnect",function(client){ //connected--; console.log("Client disconnected."); }); client.userid = uuid(); console.log(client.userid); connectedPlayers.push(client.userid); client.emit("onconnected", {playersId: connectedPlayers}); }); </code></pre> <p>client:</p> <pre><code>var socket = io.connect("1.1.1.1:1222"); console.log(socket); socket.on("connect",function() { console.log("Client has connected to the server"); }); socket.on("disconnect",function() { console.log("The client has disconnected from the server"); }); socket.on("error", function(message) { console.log("It is not possible to connect to the server: " + message); }); socket.on("onconnected", function(data) { for (var i = 0; i &lt; data.playersId.length; i++) $("#players").append("&lt;li&gt;" + data.playersId[i] + "&lt;/li&gt;"); }); </code></pre> <p>(and of course: <code>&lt;ul id="players"&gt;&lt;/ul&gt;</code>)</p>

    2. COI've changed to socket.emit() but my client doesn't seem to pick up anything, the "onconnected" function is never called on the client side.

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.
