perl dance multiple hosting @dotgeek
by gurugeek 14 Aug '12

hello, we are finalising a totally free hosting service for programmers ( dotgeek.org) We used to run this in 2004-2005 with PHP 5 etc. and we are now trying to extend the service to offer, in addition to PHP, MySQL and Ruby (Sinatra, Camping) with Dancer. I did try it yesterday and today and I think it is very interesting and we would like to add support for dancer. I have a quick question regarding the best solution for a multiple hosting environment (we are using apache with a and we have a proper security system in place). According to your deployment guide the PSGI + Apache setup will require the application URL in the vhost configuration PerlSetVar psgi_app /websites/myapp.example.com/app.pl this might be an issue if the user rename the application. In sinatra with a passenger deployment (aka mod_ruby) you can define a full public folder and through the config.ru file, that is easier to edit from the users that will have only SFTP access, you define which application you wish to run. Is there a similar option with Dancer or there is a need to declare the app name in the apache vhost configuration ? I would also welcome any feedback about this service that will essentially offer dancer + mysql + sqlite totally free. Do you think it would be interested and help users to get started ? Thanks in advance David

Hello all, I saw once somewhere an example of how to name param names in HTML forms to be able to receive structures like arrays, hash of hashes [of arrays [of hashes]], etc. I want to stop using CGI::WebIn, but could not find now that examples for Dancer' param(). Does somebody know where can it be? -- Best Regards, Nick Knutov http://knutov.com ICQ: 272873706 Voice: +7-904-84-23-130

We have "development" and "production" environments. Is it possible to add a new environment called "test" and have a separate config file for it? -- Puneet Kishor

Question regarding Dancer::Test
by Sarah Fuller 05 Aug '12

05 Aug '12

Hello Dancers! :) Firstly please forgive me for bothering all of you with my silly little issues. However I've been using dancer for a number of projects for awhile now (loving it!) and haven't come across this before. Perhaps its just the lack of sleep but I've not been able to work out what's going on. I don't expect a magic bullet but if someone out there has some suggestions that might point me in the right direction I'd be most grateful. The problem: I've been using Dancer::Test and testing the app as I go. Somehow have managed to get it into a state whereby testing any route that returns a template with say "response_status_is" returns 500. Thing is, the routes are working and returning 200. They work in the browser and they work when I check them with curl. All routes returning a serializer or indeed just doing a "return;" work fine too. I've included some example information below, happy to share any other details that may help me sort this out. I'm sure I've just overlooked something.... Thank you. Sarah Fuller ROUTE: get '/' => sub { =pod main page =cut template 'index'; }; --- TEST FILE: use Test::More tests => 2; use warnings; use strict; # the order is important use MyApp; use Dancer::Test; route_exists [GET => '/'], 'a route handler is defined for /'; response_status_is ['GET' => '/'], 200, 'response status is 200 for /'; --- TEST RESULT: perl -Ilib t/002_index_route.t 1..2 ok 1 - a route handler is defined for / not ok 2 - response status is 200 for / # Failed test 'response status is 200 for /' # at t/002_index_route.t line 11. # got: '500' # expected: '200' # Looks like you failed 1 test of 2. --- MANUAL TEST: curl -I http://localhost:3000/ HTTP/1.0 200 OK Server: Perl Dancer 1.3098 Content-Length: 9093 Content-Type: text/html; charset=utf-8 Set-Cookie: dancer.session=768955642575256601817434832617820228; path=/; expires=Sun, 05-Aug-2012 00:33:47 GMT; HttpOnly X-Powered-By: Perl Dancer 1.3098 --- CONFIG FILE: appname: "app" layout: "main" charset: "UTF-8" serializer: "JSON" session: Storable session_dir: /tmp/dancer_app session_expires: 28800 template: "template_toolkit" engines: template_toolkit: encoding: 'utf8' start_tag: '[%' end_tag: '%]' plugins: ValidateTiny: rules_dir: validation error_prefix: err_ is_full: 0 Passphrase: default: bcrypt bcrypt: cost: 12 DBIC: default: schema_class: MyApp::Schema dsn: dbi:mysql:MyApp user: user pass: pass options: RaiseError: 1 PrintError: 1

Dancer App
by djgoku 03 Aug '12

03 Aug '12

I have written an application that outputs to a number of formats including csv/tab delimited/fixed length. One option I have played with is a Dancer app that produces JSON that is consumed by the same app. Its output will be similar to excel/access in columns and rows. In my current application I tried adding 'use Dancer;' and adding a route and start line 'dance', but it looks like Dancer is clobbering Getopt::Long which I also use. I really don't want to write a separate application since I won't know until run-time on what output I want. Has anyone ever tried this before? Jonathan Otsuka
