Deploying with Plack::Handler::Apache2
by Dave Cross 21 Jan '12

21 Jan '12

I was disappointed to read this in Dancer::Deployment: NOTE: Only a single Dancer application can be deployed using the Plack::Handler::Apache2 method. Multiple Dancer applications will not work properly (The routes will be mixed-up between the applications). I've just installed my second Dancer app on the same Apache instance using Plack::Handler::Apache2 and I can confirm that the second app gets _very_ confused :/ I assume this is a Dancer limitation rather than a Plack one as I already also have a Catalyst app installed in the same Apache instance using Plack::Handler::Apache2. So I was wondering how serious this limitation is? Is it something that could be fixed if a hacker (and, yes, I'm probably volunteering myself here) spent some time investigating the problem? Or is it a hard limit that we're never going to be able to work round? Of course the answer I'd _really_ like is "oh, yes, that'll be fixed in Dancer 2.0" :-) Cheers, Dave... -- Dave Cross :: dave(a)dave.org.uk http://dave.org.uk/ @davorg

Extrange problem whith Locale::Maketext
by Angel Arancibia 17 Jan '12

17 Jan '12

Hi, I'm getting some extrange problem making Locale::Maketext to work with Dancer. The problem is that, in some "magic" combination, when we are ussing with apache2, the handler return undef. That problem does not happend when we run the application from bin/app.pl. The "Magic" combination is: /en/something -> OK -> change to /de/something -> ERROR -> wait 10seconds try again /de/something -> OK This happend only when ussing Plack::Handler::Apache2, no when we run the application from the ./bin/app.pl The code looks something like: package Extra::L10N; use base qw(Locale::Maketext); ... 1; .... use Extra::L10N; ... my $lh = Extra::L10N->get_handle($args{lang},'en'); # This fails somethime ($lh = undef ) with apache2 but it works as expected with Perl Dancer server Any help would be appreacited :) Thanks, Angel

Dancer::Forms
by T. Linden 12 Jan '12

12 Jan '12

Hello Everyone, first of all I'd like to thank the developers of Dancer so much. It's a great thing and I love it more from day to day! While I'm new to Dancer, I'm not new to perl, but were using Django as app server for a long time now. Some day I thaught: this has to be done in perl, dammit - and I discovered Dancer. However, I missed one thing, that is the forms module of Django. With forms you can validate user input, and generate forms. Since I didn't find anything near such a thing, I implemented it myself: Dancer::Forms. It does the very same as the Django forms system does: you define some fields, how they shall be validated, feed your template with it, and that's it. Beside user input validation I also added a CSRF protection feature to the module. This one could be better put into a Dancer plugin perhaps, I'm unsure... The name maybe misleading, since Dancer::Forms does in fact not depend on Dancer. So it could be used in other environments as well. I hope it is ok, to put it into the Dancer:: namespace anyway. There's still lots of things to do, like more unit tests, better debugging possibilities and - maybe - some kind of "model forms" sub module, which generates the forms from a dbic definition... Take a look: https://metacpan.org/module/Dancer::Forms best regards, Tom -- Please note that according to the German law on data retention, information on every electronic information exchange with me is retained for a period of six months.

--confdir problem
by Tomasz Konojacki 10 Jan '12

10 Jan '12

Hi! I created Dancer application using "dancer -a test" command. Here are config.yml contents: appname: "test" layout: "main" charset: "UTF-8" template: "simple" is_it_old_config_file: "yep" Additionaly, I have created another config.yml in subdirectory named cfg. It has following contents: appname: "test" layout: "main" charset: "UTF-8" template: "simple" is_it_old_config_file: "nope" lib/test.pm: package test; use Dancer ':syntax'; get '/' => sub { return config->{is_it_old_config_file} }; true; When I run application with "app.pl --confdir=cfg" command, I get "yep" instead of "nope". I tried to specify absolute path, it didn't change anything. I'm using Windows if it matters. Thanks in advance, Tomasz

utf-8 issues
by Puneet Kishor 03 Jan '12

03 Jan '12

Fellow Dancers, I am mystified by the following issue. My Dancer-powered web site converts utf-8 encoded, plain text files formatted with Markdown into html. My template is based on html5 using the boilerplate from html5boilerplate.com and has the following incantation <!doctype html>      <html class="no-js" lang="en">  <head> <meta charset="utf-8"> and my Dancer config setting has charset : utf-8 Yet, a text file that I created today using Hindi shows up as gobbledegook under Safari. The text file is perfectly legible in two different Mac OS X text editors (Coda and TextWrangler) and in the terminal using `less` and `vim`. Safari is set to detect encoding automatically, but seems like the web server (Starman) is not sending the right encoding. Any thoughts? -- Puneet Kishor
