    <p>I am creating an application that takes some file uploads and send them straight up to S3. I would prefer not to even have the tmp file on my server, so I am using the Knox module and would like to take the raw stream from Formidable and send it over Knox to S3. I have done something similar using Knox to download a file using this code:</p> <pre><code>knox.downloads.get(widget.download).on('response',function(sres){ res.writeHead(200, { 'Content-Type':'application/zip', 'Content-Length': sres.headers['content-length'], 'Content-Disposition':'attachment; filename=' + widget.download }); util.pump(sres, res); }).end(); </code></pre> <p>Now I would like to do something similar in the oposite direction (File upload from the browser to S3).</p> <p>So far I have written an event handler to capture each piece of data from the file as it's being uploaded:</p> <pre><code>var form = new formidable.IncomingForm(); form.onPart = function(part){ if(!part.filename){ form.handlePart(part); }else{ if(part.name == 'download'){ // Upload to download bucket controller.putDownload(part); }else{ // Upload to the image bucket controller.putImage(part); } //res.send(sys.inspect(part)); } } form.parse(req, function(err, fields, files){ if(err){ res.json(err); }else{ res.send(sys.inspect({fields:fields, files:files}), {'content-type':'text/plain'}); //controller.createWidget(res,fields,files); } }); controller.putDownload = function(part){ part.addListener('data', function(buffer){ knox.download.putStream(data,part.filename, function(err,s3res){ if(err)throwError(err); else{ console.log(s3res); } }); }) knox.downloads.putStream(part, part.filename, function(err,s3res){ if(err)throwError(err); else{ console.log(s3res); } }); } </code></pre> <p>But the data event only give me the buffer. So is it possible to capture the stream itself and push it to S3?</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.
