Form Validation Plugin for Dancer2
by Tushar Dave 11 Aug '15

11 Aug '15

Hello All, I am just wondering that can I use Dancer plugin with in my Dancer2 application? I would like to use Data::FormValidator for my Dancer2 application. I searched on metacpan for Dancer2 plugin for that but can not find any. I knew that Dancer already has plugin for it named Dancer::Plugin::DataFormValidator. So can i just use it? Please provide me your thoughts on this. Thanks. Best, Tushar Dave

Question about how to link hooks in Dancer2 plugin
by Rubén Amórtegui 11 Aug '15

11 Aug '15

Hello everyone, Does anyone knows if there is a way to check the hooks registered on a Dancer2 application? I'm trying to link a module that had hooks through a plugin with Dancer2. The Module itself had their hooks and works fine. But I'm not sure how to link with those hooks with a Dancer2 application. Thanks! -- ____________________________ Rubén Darío Amórtegui Medina MCE - Ingeniero de Sistemas

D2 config.yml ignoring "port"
by Warren Young 10 Aug '15

10 Aug '15

I’ve been using D1, and just tried a fresh D2 app, and ran into a TCP port conflict, so I tried adding port: 5005 to the config.yml file generated by “dancer2 -a testapp”. On restarting, it again tries binding to TCP port 5000, not 5005. I had to pass --port 5005 to plackup to get the setting to take effect. According to this page: https://metacpan.org/pod/Dancer2::Config#port-int the D1 setting still applies to D2. It’s outdated at least insofar as it claims that the default port is 3000. Did this setting simply go away with the move to D2?

Simple Dancer2::Plugin::Auth::Extensible issue
by David H 10 Aug '15

10 Aug '15

Hi All, I've been struggling with a simple example and trying to get it to work but without any luck. I'm using Dancer2::Plugin::Auth::Extensible to get users/roles and using a simple SQLite database My Config.yml is this (in relation to the database and Auth::Extensible): plugins: Auth::Extensible: realms: users: provider: 'Database' Database: driver: 'SQLite' database: 'users.sqlite' And my DancerWebsite.pm contains these relevant modules: use Dancer2::Session::Memcached; #use Dancer2::Plugin::Auth::Extensible::Provider::Database; # < not sure if I need this, doesn't work either way. use Dancer2::Plugin::Auth::Extensible; use Dancer2::Plugin::Database; I'm getting this error when trying to go to the /login route, which is: Can't locate object method "database" via package "Dancer2::Core::DSL__WITH__Dancer2::Plugin::Auth::Extensible" at /usr/lib/perl5/site_perl/5.22/Dancer2/Plugin/Auth/Extensible/Provider/Database.pm line 186, <$fh> line 12. Line 186: my $database = $self->realm_dsl->database($settings->{db_connection_name}) or die "No database connection"; get '/login' => sub { template login => {}; }; So I'm wondering if I've got something basic wrong here about the modules I'm loading or something, if anyone has had experience using this module? Thanks a lot, David

Can I convert App::Notifier::Service from Dancer 1 to Dancer2?
by Shlomi Fish 07 Aug '15

07 Aug '15

Hi all, Is there a good reason why I should *not* convert https://metacpan.org/pod/App::Notifier::Service from Dancer 1 to Dancer2? It's a simple web app, meant to run synchronously, and I can debug it by using perl -d, and last time I tried doing s/Dancer/Dancer2/g everything worked nicely. Is there a good enough reason to stay with Dancer 1?

Controller-hierarchy, best practise?
by Henk van Tijen || 06 Aug '15

06 Aug '15

Hi, perl programmer wannabee here;-) Hope this question is suited for this list. In the examples of Dancer apps I've seen there are no separate Controller classes. The sub() handlers of the routes act as a sort of mini- controllers in the examples of the documentation. But as I am starting on a project that would grow in size, I'd like use full controllers classes, like for a dashboard view that pulls in data from many data source. Where do I fit the controller classes hierarchy in? I’ve found his article http://fraley.de/2013/10/18/structuring-larger-dancer-applications/ that gives a starting point, the sample code is here https://github.com/pwfraley/DancerPrelaunch In the Fraley code, the idea of a central routes table is done away with. Instead, each controller defines its own routes it responds too. Good de-coupling practice, I suppose. But I like the default central MyDancer::App.pm package with a central routes table: - For one, it gives me in a glance an overview of all routes, the whole structure of the app. - But even more, it allows for constructs like ‘pass’ to group routes, conditionally skip routes (when not logged in or no session). - It provides a central lookaction for ‘hooks’ , process params, logging etc. (but a a base superclass Controller could be the place to do that too). On the examples of fraley.de , each controller has its own proper routes defined, but how do you combine that with the generics (loggedin, session, hooks, error) without repeating boiler plate code in each controller? To be more specific, I intend to structure my app along route definitions like: use MyDancer::Controller::FoobarController; get ‘/Foobar/jump’ => sub { my $fb = FoobarController->new; $fb->jump; }; Is this okay or ‘ugh’ ? Any more considerations or advice or pointers on how to organize a Dancer2 app with controller classes are welcome! ~henk

Some advice please on running with children etc...
by David H 06 Aug '15

06 Aug '15

Hi All, I'm running a Dancer2 app on a Windows 7 32bit machine in Cygwin (don't ask). The first thing I hope will be easy to give me advice on. The app is oddly crashing and I can't find the source of the issue but the app will be doing stuff and then suddenly just hang on the console and not go anywhere. Can I run Starman or Twiggy in such a way that there will be child processes so if the app hangs, there will be a child process to take over and serve the next request? I'm aware that MongoDB through Windows 32bit/Cygwin, isn't the most stable start to a web apps life, we are unfortunately stuck with this for the next week or two. It might last a few hours or an hour and then the app will hang. It doesn't totally crash. I'm guessing it may be something to do with the MongoDB driver but there is no error returned, the whole thing will just hang. I thought of something like Starman with --workers=10 might help? I'm currently running under Twiggy. Thanks in advance for your advice. nb. My versions of relevant stuff is: Dancer2: 0.161 MongoDB: v0.798.3.0 Twiggy: 0.1025 David

Looking for a hired hand
by Richard Reina 05 Aug '15

05 Aug '15

If anyone can help me with this please respond to me and let me know about how much you would charge. Thanks I am trying to learn dancer. Have played around with Dancer::Plugin::SimpleCRUD <https://metacpan.org/module/Dancer::Plugin::SimpleCRUD> and although I find it useful I can't find an example that applies specifically to what I want to learn. I am looking for an example app that: Brings a user to an index page similar to the "dancer -a" sample app but allows a user to either log in or else takes a user to template/page to create a minimal account (name, DOB, Gender, Email) which would result in them adding a record to a MySQL table. Once the user is created/logged in they could return to the index.tt page with their name appearing as they are logged in.
