    <p>This is not really a problem. AJAX is asynchronous by nature (<strong>Asynchronous</strong> Javascript and XML). You will have to wait until you get a response from the server to update your UI.</p> <p>If you <em>must</em> update the UI immediately, you can create an element with a placeholder ID that you can then update with the actual ID once the server responds.</p> <p><strong>UPDATE</strong></p> <p>This is in response to your comment. Webapps are not purely client-side applications. They fit into the client-server paradigm. You can try using a synchronous post, but this has the side-effect of tying up the browser until the server responds (this is due to the fact that Javascript is single-threaded).</p> <p>That being said, the response from the server should be pretty quick unless your network is slow or if whatever post your sending to the server results in some computationally-intensive operation.</p> <p>Going by the placeholder route will (as you have realized) result in all sorts of new problems that you have to deal with. You have to ensure that they are unique. Now what if they perform some operation on the client-side element before the server responds with an id? The server won't know what the placeholder id means. There are ways around this (queuing requests is one way), but it will make your code a whole lot more complicated. I don't think the tradeoff is worth it just to make the UI update faster. </p> <p>An option is to provide some visual feedback to the user that the app is "working" (i.e., while you are waiting for a response from the server). A spinner, for example.</p> <p>As far as stacking the AJAX requests, that is one approach that you can take using the <a href="http://benalman.com/projects/jquery-message-queuing-plugin/" rel="nofollow">jQuery message-queuing</a> plugin.</p>

    1. COI don't _have_ to to update the UI immediately but the beauty of client side applications is users don't have to wait around for the server to respond. I started going down the road of creating a client side temporary id which I update on response, but this wont be unique on the server side so I cant use it to post updates or destroy to the server, not with multiple users anyway. The only other idea i had was to stack the ajax request so they are asynchronous relative to the application and ui, but synchronous relative to each other.

    2. COHaving the ui up date instantly isn't really a requirement its more of a perception thing, speed being so important these days. I think though that I will accept updating the ui on response for the time being and go back and add queuing as a later stage nice to have, that plugin looks promising!

    3. CO@msaspence Good luck :) Yes, that plugin is pretty helpful. I've used it a few times myself.

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).
