    <p>I ask the browser to POST JSON data to the stream v0.5.5 server using ajax. In the server side, how can I receive the data from the ajax request?</p> <p>My client:(Google Chrome)</p> <pre><code>void ajaxSendJSON() { HttpRequest request = new HttpRequest(); // create a new XHR // add an event handler that is called when the request finishes request.onReadyStateChange.listen((_) { if (request.readyState == HttpRequest.DONE &amp;&amp; (request.status == 200 || request.status == 0)) { // data saved OK. print(request.responseText); // output the response from the server } }); // POST the data to the server var url = "/news"; request.open("POST", url, true); request.setRequestHeader("Content-Type", "application/json"); request.send(mapTOJSON()); // perform the async POST } String mapTOJSON() { print('mapping json...'); var obj = new Map(); obj['title'] = usrTitle.value == null ? "none" : usrTitle.value; obj['description'] = usrDesc.value == null ? "none" : usrDesc.value; obj['photo'] = usrPhoto.value == "none"; obj['time'] = usrTime==null ? "none" : usrTime.value; obj['ip']= '191.23.3.1'; //obj["ip"] = usrTime==null? "none":usrTime; print('sending json to server...'); return Json.stringify(obj); // convert map to String i.e. JSON //return obj; } </code></pre> <p>My server:</p> <pre><code>void serverInfo(HttpConnect connect) { var request = connect.request; var response = connect.response; if(request.uri.path == '/news' &amp;&amp; request.method == 'POST') { response.addString('welcome from the server!'); response.addString('Content Length: '); response.addString(request.contentLength.toString()); } else { response.addString('Not found'); response.statusCode = HttpStatus.NOT_FOUND; } connect.close(); } </code></pre> <p>Again, I don't want the browser to ask for data from the server! What am I doing is to asking the browser to submit the JSON data via ajax, and I just don't know how the server (Rikulo Stream v0.5.5) gets the "content" of data? All code is written in Google Dart Language M3. No Javascript!</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.

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