    <p>I made a chrome extension which calls jQuery's <code>ajax</code> method:</p> <p><strong>content-script.js</strong></p> <pre><code>[...] $.ajax({ "url": "http://localhost:5000/", "type": "PUT", "contentType": "application/json", "data": { "name": "random object" }, "dataType": "json" }); [...] </code></pre> <p>On the server side, I'm trying to fetch the information passed in the <code>data</code> attribute:</p> <p><strong>web.js</strong></p> <pre><code>[...] app.put('/', function(request, response) { console.log(request.data); }); [...] </code></pre> <p>But I'm getting <code>undefined</code> instead. How is the object passed in the <code>data</code> attribute supposed to be retrieved on the server side (<a href="http://nodejs.org/" rel="nofollow">Node.js</a> + <a href="http://expressjs.com/" rel="nofollow">express.js</a>)?</p> <p>I also tried <code>console.log(request)</code> and got a LOT of stuff in there, but nothing that looked like the info I passed along in the <code>data</code> attribute...</p> <p><strong>EDIT</strong></p> <p>My latest attempt (based on graydsl's answer) brings the following changes to the code above:</p> <ul> <li>Added <code>app.use(express.bodyParser());</code> just before <code>app.put...</code>.</li> <li>Changed <code>put</code> to <code>post</code> everywhere</li> <li>Changed <code>request.data</code> to <code>request.body.data</code></li> </ul> <p>Now, the code does what I want when responding to a form like this:</p> <pre><code>&lt;form method="post" action="/"&gt; &lt;input name="data" type="text" value="WOO HA" /&gt; &lt;input type="submit" name="submit" value="submit" /&gt; &lt;/form&gt; </code></pre> <p>However it still fails if I revert to using <code>post</code> instead of <code>put</code> (and the browser ends up on <code>http://localhost:5000/?data=WOO+HA&amp;submit=submit</code> for some reason)</p> <p>It also fails when <code>put</code>ting (or <code>post</code>ing) with ajax (see code above). When I try it with ajax, I get this on the server:</p> <pre><code>SyntaxError: Unexpected token ILLEGAL at Object.parse (native) at IncomingMessage.&lt;anonymous&gt; (/home/shawn/.node_libraries/.npm/connect/1.8.7/package/lib/middleware/bodyParser.js:135:16) at IncomingMessage.emit (events.js:61:17) at HTTPParser.onMessageComplete (http.js:133:23) at Socket.ondata (http.js:1019:22) at Socket._onReadable (net.js:683:27) at IOWatcher.onReadable [as callback] (net.js:177:10) </code></pre>

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.

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