How do I share variables between route handlers ?
by Takeshi OKURA 16 Apr '11

16 Apr '11

In Dancer.pm there is a forward example. ------------------------------------------------------------------------------------ get qr{ /demo/articles/(.+) }x => sub { my ($article_id) = splat; # you'll have to implement this next sub yourself :) change_the_main_database_to_demo(); forward '/articles/$article_id'; }; ------------------------------------------------------------------------------------ I want to the same thing. In order to that, I set the variable in first route and pass it to forwarded route. I thought I could be used to dancer's vars variables. I tried but it did not work. Set var in before filter and read it in route handler is work fine. Set var in route handler and read it in passed route handler is work fine. Set var in route handler and read it in before_template is work fine. But Set var in route handler and read it in forwarded route handler did not work. Set var in route handler and read it in before filter did not work. Perl's my and our variables outer a route handler does not used because other user session read it. I want to variables which shared in route handlers. Or I want to the filter which is called only once in every user's access. Before filter is called every time which used forward method. Waht better way to share variables in route handlers ? -- Takeshi OKURA

Arizona/Elevator -- Moose & MVC on top of Dancer
by Michael DeHaan 14 Apr '11

14 Apr '11

Hi all, I haven't packaged these github projects for CPAN just yet but wanted to share here. First off, thanks very much for Dancer -- it's exactly what I wanted from a Perl web framework. In where I'm using it, I wanted to have a simple model layer, and also to have a MVC infrastructure. Basically it adds a bit of convention around things, but leaves Dancer to do the heavy lifting. It's still pretty minimal. Compared with straight Dancer, this gets you out of maintaining routes (since the Controller plugins generate routes), and REST and error handling are done a little differently. There's also some magic around the template system I'm currently using (Mason), though I'd like to make that more pluggable so folks aren't stuck with just that. The Model layer (Elevator) is totally optional but seems to fit in well since it's also using Moose. Oh yeah, it's using MooseX::Declare everywhere -- which may or may not be a good thing depending on whether you like Moose. There are examples included in the github "examples/" dir that explain it probably a little better than I can here. Anyway, here they are: https://github.com/mpdehaan/Arizona -- Arizona, the "VC" part of the MVC https://github.com/mpdehaan/Elevator -- Elevator, the "M" part. Does SQL, NoSQL, and probably Neo4j soon. You can read a bit more here: http://michaeldehaan.net/2011/04/04/introducing-arizona-a-perl-mvc-framewor… http://michaeldehaan.net/2011/03/31/a-modern-perl-with-attitude-presenting-… Thoughts and comments welcome. These make too many choices of the user to be in a microframework, but maybe the ideas are interesting. Contributions and ideas welcome. --Michael

Dancer 1.3030 (codename "Silence of the ambs") released
by sawyer x 13 Apr '11

13 Apr '11

Hey everyone, We have just released Dancer version 1.3030, codenamed "Silence of the ambs", named after ambs (Alberto Simões). ambs has been a major part of Dancer ever since he hit our IRC channel. He is relentless in improving Dancer and has submitted more pull requests than pretty much all of us, I think: whether it was documentation, hardcore fixes (which take a lot of research and effort) or even in helping out beginners on the list (which many of us can't find the time to do), ambs is a big part of our community, and we felt he deserves the honor of a release named after him. We have a lot of people we'd like to share the same respect to, and we will in the following releases, so don't worry. :) Major changes: * send_file accepts optional content-type declaration, to override guessed MIME type. This means you can now do: send_file $filename, content_type => 'image/png'; and the likes. * send_file accepts optional absolute path. You can now use send_file to allow ANY file, not just out of the public directory. Use with caution!! * Dancer now recognizes absolute redirects. * If pass() can't match a route for you path, you'll now get a 404 instead of crashing. * Use your own templates for errors using "error_template"! Eight authors worked on this released, and at least six tickets were resolved. Thanks (in no particular order) goes to ambs, franck, sukria, schwern, racke, dams and yanick! *Dev news* Review branch: I know many of you have been waiting to integrate your pull requests, and while we do freeze the integration branch (devel) when we have a stable release candidate, we have made another branch just for reviewing your awaiting pull requests. Sukria is in charge of the "reviews" branch. It will be rebased frequently against "devel" and merged once possible. Your pull requests will remain open until they are integrated into "devel". Hooks: Our next release will focus mainly on our new hooks system Franck Cuny has written (which we will blog and write about on the list). We will pull our efforts for this one, to make it a seamless upgrade for everyone. It's gonna be pretty awesome! Till next time! Sawyer, and the Dancer crew.

Having an environments/test.yml
by Simon Wistow 13 Apr '11

13 Apr '11

I want to have some test specific stuff in an environment/test.yml (db username and password, memcache prefixes etc etc). Sounds simple enough except that in order to get it to work I had to write something like this package Dancer::TestEnviroment; use strict; use Cwd; sub import { my $class = shift; $ENV{DANCER_ENVIRONMENT} = 'test'; $ENV{DANCER_CONFDIR} = getcwd; unless ($INC{Dancer}) { require Dancer; Dancer->import(@_); } Dancer::setting(appdir => getcwd); Dancer::Config->load; } 1; and the use that from the top of ever one of my test files. Which seems a little ... long winded. Am I doing something wrong? Is there an easier way to do this?

Problem with WWW::Mechanize in Dancer

Experiencing a problem using WWW::Mechanize in Dancer. Here's how I'm using it: http://pastebin.jbldata.com/m230ae053 Note that I'm able to use the json_api_call() routine in a stand-alone script without issue; but within Dancer, the application just hangs. Any thoughts? Thanks, -Bobby
