31 Oct '18

Hey Dancer Community! On behalf of the Dancer Core Team, I am trying to get a 2018 Dancer Advent Calendar organized, and we would like your help and input! How can you help? It's simple! Are there articles covering some specific area of Dancer or its ecosystem that you would like to know more about? Just reply and let us know what you would like to see. Do you want to write an article for the advent calendar? Tell us your Dancer success stories, all about a plugin you authored, how your migration from D1 to D2 went... the sky is the limit. If you have any ideas, please submit them soon to give authors a chance to work on content for the calendar. Thanks, and happy Dancing! Jason / CromeDome

Hi All We are going through our apps to remove this error by following the instructions: Use '$self->app->request' instead However, this is not possible on ajax/post calls as $self does not exist Is there an alternate solution for this? /Z

Hi! I'm trying to get some non-unicode strings from SQLite DB using Dancer2::Plugin::DBIC and return it to user using Dancer2::Template::TemplateToolkit, but getting Latin1-encoded string (like this: Ð¢ÐµÑÑ) instead of normal text. I have charset: "UTF-8" in my config.yml.

I added a new session storage backend for Dancer2 today. Dancer2::Session::CHI is on its way to your local CPAN mirror. If you are currently using CHI in your Dancer2 applications, this will let you use CHI as your backing datastore for storage data. Please see the pod for details. Contact me with any issues you may have, or file them on the github bugtracker. Thanks! Happy Dancing! Jason / CromeDome

Dancer2 Dancer2::Plugin::Auth::Extensible::Provider::LDAP
by Attila Bárdi 11 Oct '18

11 Oct '18

Hey, I used Ldap with Dancer and it works pretty fine. Now I want to develop a new microsite, I thought it would be better with Dancer2(0.206000). But I cannot make the Ldap (0.702) authentication to work. I turned on the ldap logging. By the log It looks working, because it found the user, but the page says login failed. The second search for the groups has 0 match, the user doesn't member of any group. But I can log in with the user foo, and he is not a member of any group neither. The result is LOGIN FAILED. In the Dancer2 log says: Odd number of elements in anonymous hash at /usr/local/share/perl/5.24.1/Dancer2/Plugin/Auth/Extensible/Provider/LDAP.pm line 279.

Dancer2::Logger::Log4perl released
by Jason Crome 06 Oct '18

06 Oct '18

We’ve been missing a Log4perl plugin for Dancer2 for, well, forever, and today I have released Dancer2::Logger::Log4perl. This was originally developed by Ryan Larscheidt and Jon Miner at the University of Wisconsin. I have added a minimal test, a little pod, and wrapped a release around it. The rest of this is their work, and I cannot thank them enough for their work on this. There are more tests needed still, but I wanted to get this out in the wild as soon as I could. If you notice any issues, please report them at https://github.com/cromedome/Dancer2-Logger-Log4perl/issues Thanks, and happy dancing! — cromedome Jason A.

dancer2's send_error() from module
by icovnik 01 Oct '18

01 Oct '18

Hello, I'm using Dancer2 for some small apps and now I came across some difficulty when using Dancer2's send_error() function. This function is meant to be used to emit HTTP error to client (of course) and to stop processing current route at that point. It works OK if I use send_error() in route directly or in some subroutine in current module/package. But if I use send_error() from another module, it doesn't stop there. The same if Other module is in the same file or use'd from Other.pm. So the question: how to properly use send_error() from another module to finish the route right there on the spot? Thanks ico Example code: package Server; use Dancer2; get '/test' => sub { #send_error("err", 401); # 1: end of processing, error 401 #myfunc(); # 2: end of processing, error 402 Other::func(); # 3: processing continues, route returns 200 OK return "OK"; }; sub myfunc { send_error("err", 402); # never hits this spot } 1; package Other; use Dancer2; sub func { send_error("err", 403); # happily continues here } 1;
