Session Engine - error
by Scott H 02 Feb '17

02 Feb '17

Hi Everyone, Long time Dancer user, currently migrating a system over to Dancer2 from Dancer and not really into using Dancer2::Session::DBIC so I am converting some of the Dancer::Session::DBI over with what I need. I am reaching out because I am at a point where I don't know what else to do to make this work. It seems to be generating sessions into my database table but with no session_data, only id's. Right after I would login this error pops up. *Console:* Exception caught in 'core.app.after_request' filter: Hook error: flush() called outside streaming response at /home/scott/perl5/lib/perl5/Dancer2/Core/Role/DSL.pm line 76. *Web:* Internal Server Error Exception caught in 'core.app.after_request' filter: Hook error: flush() called outside streaming response at /home/scott/perl5/lib/perl5/Dancer2/Core/Role/DSL.pm line 76. at /home/scott/perl5/lib/perl5/Dancer2/Core/App.pm line 35. at /home/scott/perl5/lib/perl5/Dancer2/Core/Role/Hookable.pm line 115. I don't have a repo yet but a gist will work *Code:* https://gist.github.com/scottscreations/5bf8f3a027f328dc0733f6d3683ccb8e Thanks, Scott

Re: [dancer-users] Social Media Sign-up/Sign-in

Hi Dave, I'm using Dancer2::Plugin::Auth::OAuth with Google and Facebook providers. It works. Paulo -------- Original message --------From: Dave Cross <dave(a)dave.org.uk> Date: 01/02/2017 11:38 (GMT+00:00) To: dancer-users(a)dancer.pm Subject: [dancer-users] Social Media Sign-up/Sign-in For a side project web site I'd like to offer users the ability to sign-up and sign-in using their existing social media accounts. Looking at other web sites these days, it seems to be pretty much expected that you can do that. But I have no idea where to start adding this feature to my (Dancer2) app. So what I'm hoping is that someone else somewhere in the Dancer community has done this before and has code that I can steal^Wstudy. Any information you can share would be massively appreciated. And if I work out what I'm doing, I promise I'll produce a Dancer2 plugin to simplify the process and/or an article or two explaining how it's done. Cheers, Dave... _______________________________________________ dancer-users mailing list dancer-users(a)dancer.pm http://lists.preshweb.co.uk/mailman/listinfo/dancer-users

Dancer2 app deployment
by Matthew Mallard 31 Jan '17

31 Jan '17

I’m not sure if anyone else is using Puppet to manage their systems, but if you do, this may be of interest to you. I’ve written a Puppet module that installs a systemd service for Dancer2 apps (other PSGI apps should work too): https://forge.puppet.com/qtechnologies/psgi I generally deploy my code with rsync and was using a script to start the apps, but it was starting to get messy as the number of apps grew. This way I know the service files will be installed consistently and the app will run automatically when it’s in production. It also fits in well my Nginx module, so a little bit of hiera data sets up Nginx proxying Dancer and using Let’s Encrypt certs. See here if that grabs your interest too: https://forge.puppet.com/qtechnologies/nginx Cheers, Matt

Dancer2 0.204003 fixes missing dependencies, improves error handling
by Jason A. Crome 25 Jan '17

25 Jan '17

>From http://blogs.perl.org/users/jason_a_crome/2017/01/dancer2-0204003-fixes-mis…: Dancer2 0.204003 is on its way to CPAN now, and provides the following changes: - The CPANTS testing service reported that some dependencies for Dancer2 were not specified in the distribution. This has been corrected, and we apologize for any issues this may have caused. - When a route exception occurred, Dancer2 would catch the error first, and would prevent any custom exception handling from trapping the exception. There were some ugly hacks for working around this, but this fix puts things right, and lets the exception hook fire first, and then will trap the error. - Several changes were made to Dancer2's Template Toolkit integration, the most significant of which being the removal of the ANYCASE option. - Various documentation improvements. A big thank you to those who contributed to this release and helped get it out the door. The full changelog is as follows: 0.204003 2017-01-25 15:21:40-06:00 America/Chicago [ BUG FIXES ] * GH #1299: Fix missing CPANTS prereqs (Mohammad S. Anwar) [ ENHANCEMENTS ] * GH #1249: Improve consistency with Template::Toolkit, using correct case for 'include_path', 'stop_tag', 'end_tag', and 'start_tag', removing ANYCASE option. (Klaus Ita) * Call route exception hook before logging an error, allowing devs to raise their own errors bedore D2 logging takes over. (Andy Beverley) [ DOCUMENTATION ] * Add another example of the delayed asynchronous mechanism (Ed @mohawk2 J., Sawyer X) * GH #1291: Document 'change_session_id' in Dancer2::Core::App. (Peter SysPete Mottram) * Fix typo in Dancer2::Core::Response (Gregorr Herrmann) * Document Dancer2::Plugin::RootURIFor (Mario Zieschang) Happy Dancing!

Dancer2::Plugin question
by Andrew Solomon 23 Jan '17

23 Jan '17

Hello People, I'm just catching up with the new and funky Dancer2::Plugin and I want to make sure I've understood the rationale of why it doesn't load 'strict' and 'warnings' for you like Dancer2 does. Is this because when you're writing a plugin, you're writing Perl rather than an application in the Dancer domain specific language?

Updating to the new Dancer2 plugin system
by Amelia Ireland 13 Jan '17

13 Jan '17

Hello Dancers, What's the recommended procedure for converting a plugin that may import an unspecified number of keywords into the app? I use Dancer2::Plugin::LogContextual <https://github.com/wchristian/Dancer2-Plugin-LogContextual>, which imports a set of keywords via use Log::Contextual ':log' and redefines $SIG{__WARN__} for the application by adding an around method modifier to to_app. I'm unsure of the best way to handle this with the new plugin system (I am not the plugin author). A sample of the plugin code: around to_app => sub { my ( $attr, $self, @args ) = @_; my $app = $self->$attr( @args ); return sub { local $SIG{__WARN__} = sub { my @args = @_; log_warn { @args }; }; return $app->( @_ ); }; }; Any hints gratefully received. Thanks!

Dancer2::Plugin::LogReport - basic setup
by Nathan Bailey 04 Jan '17

04 Jan '17

Hi all, I'm endeavouring to use Dancer2::Plugin::LogReport so that all our errors go to one log file. As I understand the documentation (POD in Dancer2::Plugin::LogReport), I need to: 1. Add logging information to my yml 2. Add use Log::Report (); and use Dancer2::Plugin::LogReport mode => DEBUG; to my main route handler module 3. use Log::Report; in my modules Presumably, however, I need to tell the modules about my Log::Report configuration. Does this mean I need a: dispatcher 'FILE', 'log', mode => 'DEBUG', to => '/path/mylogfile.log'; in every method/subroutine? I assume not, but I can't see how the non-Dancer2 modules are getting the config information since they are ignorant of the .yml file. thanks, Nathan

Upgrade issue (maybe)
by Clive Eisen 04 Jan '17

04 Jan '17

I am moving a working Dancer2 app from centos6 to 7 When running it I get Class::XSAccessor: invalid instance method invocant: no hash ref supplied at /usr/local/share/perl5/Dancer2/Core/Role/Serializer.pm line 71. I have narrowed it down to a single line - if I comment this out the app starts fine - albeit with the data from $file_string missing and therefore useless $sql_config = from_yaml($file_string); But why on earth is it failing at compile time? Working on 6 - Dancer2 0.160003 Not working on 7 - Dancer2 0.204002 Downgraded 7 to 0.160003 - works have I missed something that changed between versions of Dancer2? TIA — Clive Eisen GPG: 75056DD0

Race standings website
by Todd Rinaldo 12 Dec '16

I'm looking to open source a car race standings website in Dancer2 for a common Cub Scouts event called Pinewood Derby. Before I code it from scratch, I thought I'd ask if anyone knows of something similar I could steal from? Thanks, Todd
