how to change drop down list on different tabs
by Wanjuan Yang 24 Mar '16

24 Mar '16

Hi, I have a template: The first part is a form with a drop down list. The second part of the template consists different tabs. By selecting from the list, it shows different content in the second part of the template. But I want to change the drop down list content when switch between tabs. How can I do it? The simplified version of the codes look like: <div class="panel"> <h3 >Select a tissue specific analysis: </h3> <div class="filt_options"> <form action=“/someaction/&" method="post" autocomplete="off"> <select name="tissue" class="tissue_selector"> <?pl foreach my $tissue ( @$tissues ){ ?> <option value="[== $tissue->[1] =]"> [== $tissue->[0] =]</option> <?pl } ?> </select> </form> </div> <div class="sub_data" id="tissue_selection”> <ul class="tabs"> <li><a href="#t_first">Overview</a></li> <li><a href=“#t_second”>Plot</a></li> </ul> <div id="t_first" class=“overview”> </div> <div id=“t_second” class="plot"> </div> </div> </div> Many thanks, Wendy

Setting cookie name at runtime
by Clive Eisen 22 Mar '16

22 Mar '16

Hello I have a dancer2 app that uses Dancer2::Session::Cookie and Dancer2::Plugin::Auth::Extensible And I can set the cookie name in the config file The app, however, serves multiple domains, and serves different content based on 1) The user and 2) the domain of the request This all works as expected except I would like to have different cookies for each domain so a single user can be looged in more than once with different credentials on the same browser I have tried set session_cookie => ‘blah1.dancer.cookie’ and config->{engines}{session}{Cookie}{cookie_name} = “blah1.dancer.cookie” in the before hook, but neither seem to affect the cookie name Is what I am trying to do impossible? If I have missed it in the docs I appoligise TIA -- Clive Eisen GPG: 75056DD0

Looking at that now Did this work out for you? I'm currently trying to deploy a similar setup, with X-Forwarded-Host and X-Forwarded-Protocol as suggested in Dancer2::Config, but the "behind_proxy" config setting is being ornery. I've got it set to 1 in all three config files (overkill), and the "is_behind_proxy" request flag is ALWAYS 0! I'm still debugging it here... Thanks! PS, I'm using Dancer2 0.152000 on Debian Jessie. -- C. Chad Wallace, B.Sc. The Lodging Company http://www.lodgingcompany.com/ OpenPGP Public Key ID: 0x262208A0

Introducing new plugin for Dancer2: Swagger2
by Daniel Böhmer 16 Mar '16

16 Mar '16

Hello Dancer folks, as recently announced I got the permission to upload one of my Perl modules to CPAN and did so during the German Perl Workshop. Unfortunately I've been sick over the last week and didn't have the chance to tell you about it in the workshop. So I want to describe it via e-mail: https://metacpan.org/pod/Dancer2::Plugin::Swagger2 There is a fully functional example in the SYNOPSIS section that displays the whole point: Define paths of your REST API in the generic Swagger alias OpenAPI specification format. Then throw that file onto Dancer2 and get input validation, output validation and route creation for free. As our own application is still in development we turned off validation there for now. So I have to admit that validation is still a bit flaky and not well tested. In fact I stole much of the logic from Mojolicious::Plugin::Swagger2 without understanding all of it. Any users, testers or contributors are welcome. I hope to get some feedback via e-mail or on Github. When you're going to develop your next REST API be sure to write a specification in Swagger/OpenAPI format and if you did so, you can also speed up the implementation in Dancer2 with this plugin! Kind regards Daniel Böhmer

Dancer and HTML5 video
by Richard Reina 10 Mar '16

10 Mar '16

Does anyone know if there is anything related to an NGINX->Starman->Dancer stack that would prevent html5 videos from playing on safari iOS (on an Iphone or Ipad)? I realize that such a idea seems unlikley, but this embeded video http://www.w3schools.com/html/html5_video.asp plays on my ipnone. However, when I download the video and put in my Dancer2 app and use their markup (below) the video plays perfectly on a desktop but will not play on my Iphone. Being that I am downloading their video it cannot be an encoding issue. <h3>HTML Video Example. Courtesy of <a href="http://www.bigbuckbunny.org/" target="_blank">Big Buck Bunny</a>.</h3> <div class="w3-padding w3-white notranslate"> <div style="text-align:center"> <video id="video1" style="width:600px;max-width:100%;" controls> <source src="user_vids/uploads/user_vidL_5_111222333.mp4" type="video/mp4"> <source src="user_vids/uploads/user_vidL_5_111222333.ogv" type="video/ogg"> Your browser does not support HTML5 video. </video> </div> </div> Thanks, for any help.

Dancer NGINX configutation
by Richard Reina 08 Mar '16

08 Mar '16

I have the following nginx configuration that I believe -- or at least hope -- serves up my static files, like images ad videos, directly without invoking my dancer app. Can anyone tells me if this is the case or not, or how I can test to see if they are indeed being served directly by NGINX? server { listen 80; server_name mydomain.com; rewrite ^/(.*) https://mydomain.com/$1 permanent; } server { listen 443 ssl; server_name mydomain.com; ssl_certificate /home/starman/mydomain.com.chained.crt; ssl_certificate_key /home/starman/mydomain.com.key; client_max_body_size 20M; location / { # Serve static files directly: if (-f $request_filename) { expires 30d; break; } proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://localhost:5000; } }

Fwd: Setting cookie_domain on the fly
by Gabor Szabo 08 Mar '16

08 Mar '16

Hi, I'd like to server two separate domains from the same code-base and even the same process. Currently I set the cookie_domain in the configuration file, but that will not be good once there are two domains. Is it possible to set the cookie_domain on the fly in the code? This is what I have now: engines: session: YAML: cookie_domain: ".example.com" regards Gabor

Milestone
by Zahir Lalani 08 Mar '16

08 Mar '16

Hi All Just wanted to say a big thank you to you all. We started a major development of a multi-tenanted enterprise app last April. We have just gone live with our first phase and first client. Dancer has been a real pleasure to work with. We still get weird looks when we have to explain the use of perl in an enterprise application - but the results speak for themselves! Thx all Z
