D2: Where should I place the config.yml file?
by Punter 22 Jun '13

22 Jun '13

It's not clear at all from Dancer2's documentation: "Dancer2 will first look for the file /config.ext / (where .ext is the type of configuration file you are using) in the root directory of your application." What is "the root directory of my application"? All I know is that I created a simple app.psgi in some directory and running it with plackup. I placed config.yml right next to it, but it's not getting read. Can we please fix the documentation a bit so it makes more sense? Thanks,

Managing session in before hook
by Cymon 21 Jun '13

21 Jun '13

Hi all, what is the right way to manage session in a before hook? I need to write a session key during the before hook execution, to retrieve it in dispatcher (to render the value). I tried many ways like: hook before => sub { my $context = shift; ... session 'foo' => 'bar'; $context->app->session->{'foo'} = 'bar'; $session = $context->session; $session->write('foo', 'bar') } but everytime nothing arrives to the dispatcher and nothing is actually written (I used Session::YAML to test this). Where am I wrong? -- Cymon Coniglio domina, http://www.therabbit.it

load_app, prefix, require_login (or role)
by Henk van Oers 14 Jun '13

14 Jun '13

I am using Dancer::Plugin::Auth::Extensible but what I want is more general. I use in my app: prefix '/user' => sub { get '/' => require_login sub { my $user = logged_in_user; template 'user', { user => $user }; }; }; No problem with that. I also use in my app: load_app 'Bla', prefix => '/bla'; I would like to restrict the routes to that app to only users with a matching role. That would make "load_aps"s reuseable for other apps with a differend role mechanisem. e.g. In Bla.pm you can have: get '/request' => sub { my $req = request; reveal('request', \$req); }; In contrast to: get '/foo' => require_role($i_do_not_know_the_role) => sub { ... }; -- Henk PS: any '/logout' => sub { session->destroy; redirect '/'; }; Can be a global route for any Danser app, if there is nothing to match anymore.

How to cite Perl Dancer
by Michael Wolfinger 10 Jun '13

10 Jun '13

Hi All, while we've built a little bioinformatics application based on Dancer (http://rna.tbi.univie.ac.at/TSSAR) and are currently writing a paper about it, I was wondering how to correctly cite the Perl Dancer project. Is there any official manuscript around apart from the Dancer website? Best, Michael

Users of DPAE, ---- %<---- $ grep request Extensible.pm return redirect uri_for($loginpage, { return_url => request->path }); return redirect uri_for($loginpage, { return_url => request->path }); return redirect uri_for($deniedpage, { return_url => request->path }); This is developed on GitHub - please feel free to raise issues or pull requests ---- >%---- I am building an app with Dancer::Plugin::Auth::Extensible Apache deployment like this: AddHandler fastcgi-script .fcgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ /dispatch.fcgi/$1 [QSA,L] I do not want the SCRIPT_NAME but I do want the query_string "?foo=bar" in the return_url. Changing "request->path" into "request->request_uri" does it for me. Is this the "right" patch? -- Henk

by Yanick Champoux 06 Jun '13

Thanks to berekuk++, D::P::Auth::Twitter v0.04 uses v1.1 of the Twitter API REST[1]. As Twitter will phase out v1.0 as of June 11th, if you are using that plugin, you might consider upgrading. Just sayin'. :-) Joy, `/anick [1]: https://github.com/PerlDancer/Dancer-Plugin-Auth-Twitter/pull/7
