    <p>I've got a Pylons controller with an action called <strong>serialize</strong> returning <code>content_type=text/csv</code>. I'd like the response of the action to be named based on the input patameter, i.e. for the following route, produced csv file should be named <code>{id}.csv</code> : <code>/app/PROD/serialize</code> => <code>PROD.csv</code> (so a user can open the file in Excel with a proper name directly via a webbrowser)</p> <pre><code>map.connect('/app/{id}/serialize',controller = 'csvproducer',action='serialize') </code></pre> <p>I've tried to set different HTTP headers and properties of the webob's response object with no luck. However, I figured out a workaround by simply adding a new action to the controller and dynamically redirecting the original action to that new action, i.e.:</p> <pre><code>map.connect('/app/{id}/serialize',controller = 'csvproducer',action='serialize') map.connect('/app/csv/{foo}',controller = 'csvproducer', action='tocsv') </code></pre> <p>The controller's snippet:</p> <pre><code>def serialize(self,id): try: session['key'] = self.service.serialize(id) #produces csv content session.save() redirect_to(str("/app/csv/%s.csv" % id)) except Exception,e: log.error(e) abort(503) def tocsv(self): try: csv = session.pop("rfa.enviornment.serialize") except Exception,e: log.error(e) abort(503) if csv: response.content_type='text/csv' response.status_int=200 response.write(csv) else: abort(404) </code></pre> <p>The above setup works perfectly fine, however, is there a better/slicker/neater way of doing it? Ideally I wouldn't like to redirect the request; instead I'd like to either rename <code>location</code> or set <code>content-disposition: attachment; filename='XXX.csv'</code> [ unsuccessfully tried both :( ]</p> <p>Am I missing something obvious here?</p> <p>Cheers</p> <p><strong>UPDATE:</strong> Thanks to <strong><em>ebo</em></strong> I've managed to do fix <code>content-disposition</code>. Should better read W3C specs next time ;)</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.
