Dancer2 sessions and cookies?
by Gabor Szabo 06 Dec '13

06 Dec '13

I am trying to add sessions to my new Dancer2 based applications and it drives me crazy as usual. In config.yml I added session: YAML in my login route I added session last_seen => time; Running the applications using plackup -L Shotgun bin/app.pl and accessing it via http://localhost:5000/ (though I get the same behaviour with perl bin/app.pl as well) after I pass the login route I see a new yml file created in the sessions/ directory but when I check my browser I don't see any cookies from localhost and when the code checks in the next get request if (session('last_seen')) it is false. My understanding is that Dancer should set a cookie with the id of the session which is the name of the yml file in the sessions/ directory. What do I need to configure in order to get this working?

Dancer and Coffeescript
by Pierre M 06 Dec '13

Hi everyone, I have managed to make Coffeescript work with my Dancer2 app, but I'm facing an additional challenge: Source maps won't work, and I'm guessing it might be caused by my files structures. If anyone has managed to use Dancer with Coffeescript's source maps, I would appreciate some help. My file structure is simple: all my .coffee files are in public/coffee. And their .js and .map counterparts are in this same folder too. Here is what I've done in bin/app.pl to make my plack server compile the .coffee files to .js: #!/usr/bin/env perl use FindBin; use lib "$FindBin::Bin/../lib"; use HabitLab; use Plack::Builder; builder { enable 'Compile' => ( # Plack::Middleware::Compile pattern => qr{\.coffee$}, lib => 'public/coffee', blib => 'public/coffee', mime => 'text/plain', map => sub { my $filename = shift; $filename =~ s/coffee$/js/; say " * FILE: $filename"; return $filename; }, compile => sub { my ( $in, $out ) = @_; say " * IN: $in, OUT: $out"; system("coffee --compile --map --stdio < $in > $out"); } ); HabitLab->dance; }; So far I've only created the .map files manually with coffee -cm *.coffee from inside the public/coffee folder. I've tried to modify the source paths inside the .js and .map files, with no success. Any idea of what I might have missed? --- I check email a couple times daily; to reach me sooner, you can send me a text message via this page: https://awayfind.com/mascip

plack middlewares not loaded from config.yml
by Pierre M 06 Dec '13

Hi dancers, I manage to load Plack middlewares from app.pl, but not from the config.yml file. *** In *app.pl* I have: use Plack::Builder; builder { enable 'Debug', panels => [qw<Memory Timer>]; HabitLab->dance; }; which works. *** Here is what i put in *config.yml* instead (and which doesn't work) : layout: "main" plack_middlewares: - - Debug - panels - - Memory - Timer I know that the config file is used, because my layout is used. And I know that this YAML is valid, and produces the following structure (outputed with Data::Printer) : \ { plack_middlewares [ [0] [ [0] "Debug", [1] "panels", [2] [ [0] "Memory", [1] "Timer", ] ] ] } What I don't understand, is why the middleware doesn't work in this case. Any idea? I've followed the examples from here and there: http://advent.perldancer.org/2011/16 http://search.cpan.org/dist/Dancer/lib/Dancer/Cookbook.pod#Plack_middlewares

setting header before redirect
by Nuno Carvalho 03 Dec '13

03 Dec '13

Hello everyone, I have two simple Dancer 1 apps, I'm creating a specific header in one, and then redirecting to the other application. I would expect to find the custom header in the second application, but I don't see it. I'm also using Data::Dumper to view the request in the second application and I don't find the header there either. Here's the route for both applications: http://paste.perldancer.org/PtkO0HkfPev Am i doing something wrong? Any insight would be appreciated. Thank you in advance nrc

Setting static files to 304 - Not modified
by Matt Mallard 03 Dec '13

03 Dec '13

Hi, I've using Dancer2 with Plack/mod_perl with Apache (I was previously using Dancer with CGI, but can't get CGF or FCGI to work with Dancer2). How to I set my static files to report '304 - Not modified' to the browser? When I use Firebug to look at all the file load times and turn browser caching on, all the files from CDNs report '304 - Not modified', but all those served through Dancer report as '200' and hence are transferred each time. This is fine for the dynamic pages, but unnecessary for the static files (logos, css, javascripts). Thanks, Matt
