    <p>So I would like to be able to run custom function through socket.io using node My basic idea is fairly simple, I just can't get it to work. Generally speaking you would write something similar to this to run a function on incoming message...</p> <pre><code>//server socket.on('incomingMessage', function(data) { console.log(data); io.sockets.emit('newMessage', {id: data.id, from: data.name, message: data.message}); }); //client socket.on('newMessage', function(data) { $('#messages').html($('#messages').html() + data.message); $('#from').html($('#from').html() + data.from); }); </code></pre> <p>but what I would like to do is allow that to be much more dynamic and actually pass the function I want to run in the message itself, so something like this...</p> <pre><code>//server socket.on('customFunction', function(data) { console.log(data); io.sockets.emit('runFunction', data); }) //client socket.on('runFunction', function(data) { for(var index in data) { args.push(data[index]); } data.fn.apply(this, args); }); </code></pre> <p>but when I call this from a client using something like...</p> <pre><code>socket.emit('customFunction', {id: sessionId, name: user.name, callBack: function() { alert('it worked'); } }); </code></pre> <p>on the server the only thing it logs is the session id and the name, the callBack(regardless of the name, I have tried func, run, cb, callBack, customFunc) just disappears. so I am kind of at a loss. Anyone have any ideas? thank you in advance for the help. I am not sure why, but when calling this it only logs the session id and the name elements, the callback, or fn, or whatever else, just isn't there. Does node or socket.io remove functions from arguments when sending things off?</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.
