Need a CRUD kickstart
by Richard Reina 04 Aug '15

04 Aug '15

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. Does anyone know where I can find such an example? Thanks

Template creation
by Richard Reina 04 Aug '15

04 Aug '15

Been trying to teach myself dancer over the last several days and have begun to grasp the basics of creating a very simple CRUD. However, I am beginning to realize that I need to know HTML. Would to best plance for some who does not know html be to simply copy index.tt, edit it to create templates? Or is there a better easier way? Thanks

When I do this it works.#!/usr/bin/perluse Dancer;use Dancer::Plugin::SimpleCRUD;# Simple example:simple_crud( record_title => 'Sponsor', prefix => '/sponsor', db_table => 'patron', editable => 1, deletable => 'no', sortable => 'yes', labels => { # More human-friendly labels for some columns ID => 'Player ID', first_name => 'First Name', last_name => 'Last Name', email => 'Email', }, );dance;But, when I add a second record/route --like below. The second one works but the first does not.richard@gemini:~$ wget -O - http://0.0.0:3000/sponsor--2015-08-03 09:19:22-- http://0.0.0:3000/sponsorResolving 0.0.0 (0.0.0)... 0.0.0.0Connecting to 0.0.0 (0.0.0)|0.0.0.0|:3000... connected.HTTP request sent, awaiting response... 404 Not Found2015-08-03 09:19:22 ERROR 404: Not Found.Any insight as to what I am doing wrong? Thanks.#!/usr/bin/perluse Dancer;use Dancer::Plugin::SimpleCRUD;# Simple example:simple_crud( record_title => 'Sponsor', prefix => '/sponsor', db_table => 'patron', editable => 1, deletable => 'no', sortable => 'yes', labels => { # More human-friendly labels for some columns ID => 'Player ID', first_name => 'First Name', last_name => 'Last Name', email => 'Email', }, record_title => 'Player', prefix => '/player', db_table => 'jugador', editable => 1, deletable => 'no', sortable => 'yes', labels => { # More human-friendly labels for some columns ID => 'Player ID', first_name => 'First Name', last_name => 'Last Name', SEX => 'Gender', email => 'Email', }, );dance;

Sorry for noise. There was no confirmation of the final message. I have the exact same issue - the return of an object used to work fine - the code I have was tested 2 months ago with no issues. We have of course been updating modules and dancer, and coming back to this project, the serialiser now gives the Route Exception error just like for John. I will test out his solution - can I get confirmation that this is indeed the way to properly handle it, or is this a bug?

Multiple config files for Dancer2 app
by Amelia Ireland 21 Jul '15

21 Jul '15

Hello all, Is there a recommended method for using multiple configuration files for a Dancer2 application in addition to the config.xxx and development.xxx/production.xxx files? My app uses a couple of databases with passwords that are changed on a regular basis, and I'd like to be able to drop DB config files into the environments folder and have them automatically included rather than having to edit config files by hand or regenerate them by script. If there's something that already exists that I can use, that would be great! Thanks! Amelia.

Examining incoming POST headers.
by Vincent Freeman 20 Jul '15

20 Jul '15

Hi guys, I'm new to Dancer2 and I'm trying to access an authorization header, similar to Github's 'X-Hub-Signature'. I consulted with https://metacpan.org/pod/distribution/Dancer2/lib/Dancer2/Manual.pod#header… says to use 'headers' to "Adds custom headers to responses" and 'header' to "adds a custom header to response", but it does not say how to retrieve the header information, rather than adding it. I'm using starman with nginx as the forward proxy. This is my code for testing header access: post '//hook' => sub { my $hd = header "Content-Type";; "Your Headers: [".$hd."]"; }; When I issue a curl, it returns empty. What am I doing wrong? Feedback welcomed and thanked in advance. Cheers, Vince.

Upgrade to HTML 5
by Kadir Beyazlı 19 Jul '15

19 Jul '15

Hi All, I did some small changes at html definition by upgrading to html5 and committed to github. Some people may think that they are not critical changes but I think that it is important for new people starting Dancer2. For example, when I started Dancer2 approximately 2 months ago and saw HTML4 definitions instead of HTML5, I thought that it is an old framework, and developing stopped long time ago. I think we can also upgrade jquery version from 1.11.1 to 1.11.3 at views/layouts/main.tt file. I know that user can change it but I think these are important for first impression to new people. jquery has versions 1.2.* but some internet explorer versions are not supported at 1.2.* series so I am not sure if needed to use 1.2.* series. *Kadir Beyazlı* *GSM : +90 535 821 50 00*
