Hi >From what I can tell, sendfile uses the psgi layer to stream the file. So presumably it still ties up a web worker (e.g. starman)? Has anyone thought of adding the ability for sendfile to utilise xsendfile so that it can be totally offloaded to the proxy web server? Z

Which plugin do you use?
by Gabor Szabo 03 May '15

03 May '15

Hi, I am creating a list of Dancer/Dancer2 plugins that are used. It can't be really scientific, but probably better than nothing. Could you please send me a list of Dancer or Dancer2 plugins you use in your projects? I'll publish the aggregate. Private e-mail is good, I won't include your name in the report, unless you say "it is ok to include me and/or my company name in the report". regards Gabor

How do I call a script from a template?
by John J. McDermott, CPLP 01 May '15

01 May '15

In a template I invoke (successfully) from a Dancer2 path I have some jquery that works outside Dancer2: $.post('/data1.pl',data,function(returnData){ $('#func').html(returnData) This code calls data1.pl and stuff its output into the div func. I know data1.pl works in a non-Dancer2 environment. But I cannot figure out where to put data1.pl so it can be run from the template. I tried just putting it in the dancer public (where the css folder, dispatch.cgi and such are), but that didn't work. I tried even to run it from the browser command line and the browser wants to download it. The directory has +ExecCGI and Dancer2 runs. Where should I put this file and what must I do so I can run it? Thanks! --john -- John J.

Dancer + objects + database
by Juan José 'Peco' San Martín 01 May '15

01 May '15

Hello all, First, thank you for this awesome work! I have a Dancer application that uses Apache + Plack::Handler to run it. Currently, inside each Dancer route I'm forced to create the master object of the application (i.e $object=Myapp->new(-login=>$login)) that it's a huge structure, including the database handler. So: /route1 => creates the $object, reconnects to the database /route2 => creates the $object, reconnects to the database Yep, doesn't make sense... Is there a way to make the $object persistent (and the database connection with it)? Is this related to how the application is running (CGI)? Thank you! Peco
