Perl Dancer eBook - crowdfunding campaign
by Gabor Szabo 23 Sep '17

23 Sep '17

Hi there, I am planning to write an eBook on creating a "Single Page Application with Perl Dancer". In case you are not familiar with the term, a Single Page Application is one that does the HTML generation in the browser using JavaScript and that communicates with the server via AJAX requests sending JSON blobs back and forth. On the back-end it is usually a single page returning HTML and then the rest is API. (pun not intended but might work well :) I am going to use Dancer 2 for the back-end. The most well known example is Gmail, but plenty of other sites use this technique behind their authentication system. Reading this book will allow you to build such a site. In order to gauge the interest I am running a crowdfunding campaign. Support it to ensure I can write the book and that you get access to the content when the eBook is ready or even while as I am writing it. https://www.indiegogo.com/projects/ebook-single-page-application-with-perl-… regards Gabor ps. If you have questions, don't hesitate to ask me! -- Gabor Szabo http://szabgab.com/ Perl Maven http://perlmaven.com/ Perl Weekly http://perlweekly.com/

I found out I had to be in the app directory to run the script. So you can make a sh file that cd's into the app dir to run it at least if you plan on using cron. It took me a long time to figure that out. I would be interested to see what others say.

Weird database plugin issue
by Zahir Lalani 22 Sep '17

22 Sep '17

Hi All Hoping someone can help We of course use dancer2 as a web app, but we also have some back end services that run as command line/service items. We include Dancer in those as we get a lot of the benefits. We recently started to use database calls in those backend tools but we are getting odd results. In some setups they work, in others we get this error: Use of uninitialized value in subroutine entry at /usr/local/share/perl5/Dancer2/Plugin.pm line 532. Undefined subroutine &main:: called at /usr/local/share/perl5/Dancer2/Plugin.pm line 532. I have setup a simple test that shows the failure: #!/usr/bin/perl use lib '/var/www/OMG/lib'; use Dancer2 appname => 'OMG'; use strict; use warnings; use Data::Dumper; use Dancer2::Plugin::Database; debug "begin \n"; my $sth = database->prepare("select * from public.external_application_token_get('')"); debug "end \n"; its related to the latest version of the plugin 2.17. 2.14 works. Any clues?
