dancer2's prototype is there, feedback needed
by sukria 05 Oct '12

05 Oct '12

Hi there, I am very glad and proud to announce here that I've came up with a prototype of dancer2 that pleases me enough to be advertised. -*- https://github.com/sukria/dancer2 -*- dancer2 is a complete rewrite of Dancer aiming at providing the same awesomeness with the following major changes: - no more globals in the core - 100% object-oriented backend (based on Moo) - better scoping for sub-applications - better design (no more encapsulation violations, Law of Demeter, ...) The prototype I've pushed to GitHub currently covers ~80% of the DSL of Dancer. It's able to run simple applications (it can run the PerlDancer.org website for instance). Of course, with your real-life applications, it will break in many places in this current shape, and this is where you can help. I'd like to have as many reports as possible regarding upgrades tests. You can test very easily your app with dancer2: $ git clone http://github.com/sukria/dancer2.git $ cd YOUR_APP $ perl -I../dancer2/lib bin/app.pl Also, important to know: most of the plugins may not be working well. Thanks a lot ;)

Dancer::Plugin::SQLSearch
by Julio Fraire 22 Feb '12

22 Feb '12

Hola amigos! I have uploaded Dancer::Plugin::SQLSearch to CPAN, which is aimed to help with the creation of simple search pages. Basically, it will take a search query and turn it into a data structure suitable for SQL::Abstract. You then supply a subroutine that takes this data structure and performs the actual search in your database. >From the plugin (and your search routine) you get the first page of results and information to build pagination links. It also saves some info in the session object to offer "back to search results" links for your destination pages. Hopefully the documentation is clear enough for you to play with this little plugin; the tests should offer some insight as well. I hope you find it useful. Happy new year, Julio Fraire

utf-8 issues
by Puneet Kishor 03 Jan '12

03 Jan '12

Fellow Dancers, I am mystified by the following issue. My Dancer-powered web site converts utf-8 encoded, plain text files formatted with Markdown into html. My template is based on html5 using the boilerplate from html5boilerplate.com and has the following incantation <!doctype html>      <html class="no-js" lang="en">  <head> <meta charset="utf-8"> and my Dancer config setting has charset : utf-8 Yet, a text file that I created today using Hindi shows up as gobbledegook under Safari. The text file is perfectly legible in two different Mac OS X text editors (Coda and TextWrangler) and in the terminal using `less` and `vim`. Safari is set to detect encoding automatically, but seems like the web server (Starman) is not sending the right encoding. Any thoughts? -- Puneet Kishor

Fwd: Dancer::Plugin::SQLSearch
by Julio Fraire 31 Dec '11

31 Dec '11

Well, that was a quick "over the weekend". The new version has been uploaded a minute ago. The new default behavior is to AND search terms when the search is over a single database field. When the query is surrounded by double quotes it is not split to allow for exact phrase searches.

Dancer::Plugin::Database 1.60 adds an on-connect hook
by David Precious 29 Dec '11

29 Dec '11

Hi all, Just in case it's of use to you in your apps, Dancer::Plugin::Database 1.60 adds a 'database_connected' hook position, to allow you to define code that should be executed every time a database connection is established (receiving the new handle as a parameter, so you can use it). Example: hook database_connected => sub { my $dbh = shift; $dbh->sqlite_create_function( 'now', 0, sub { return time } ); }; This feature was requested by Mario Domgoergen, so if it's useful to you, thank him :) Cheers Dave P -- David Precious ("bigpresh") <davidp(a)preshweb.co.uk> http://www.preshweb.co.uk/ www.preshweb.co.uk/twitter www.preshweb.co.uk/linkedin www.preshweb.co.uk/facebook www.preshweb.co.uk/cpan www.preshweb.co.uk/github

Plugin for authentication/authorization?
by Flavio Poletti 29 Dec '11

29 Dec '11

Hi All, I see on CPAN that there's Dancer::Plugin::Auth::RBAC - the code seems to be from Al Newkirk, but the distro is from XSAWYERX. On Github there's Dancer::Plugin::Authorize, again from Al Newkirk, which has been deprecated in favor of DPA::RBAC, and Dancer::Plugin::Auth::RBAC from PerlDancer, which seems quite outdated with respect to its CPAN counterpart. I'd like to contribute and I'd avoid forking to a brand new project... do you know whether it is possible somewhere? Cheers, Flavio.

FOSDEM Perl dev-room
by Stefan Hornburg (Racke) 22 Dec '11

22 Dec '11

Hello, fellow Dancers! Last year I visited FOSDEM for the first time with Jure, my colleague from Ljubljana. We listened to a number of great talks, especially the furious praise of Dancer delivered by Sawyer. Now the call for speakers 2012 is out: http://nxadm.wordpress.com/2011/12/21/perlfosdem2012-cfs/ I'm wondering whether any Dancer people are going to next year's FOSDEM, so we can coordinate talks for the dev-room. There should be a least one Dancer talk there - maybe about Dancer 2? My plan is to go there and deliver my "Modern PerlCommerce" presentation, which I also submitted for Perl Oasis (http://www.perloasis.info/opw2012/) Perl Workshop Israel (http://act.perl.org.il/ilpw2012/) and going to submit for the German Perl Workshop (http://conferences.yapceurope.org/gpw2012/) Needless to say that this project is based on Dancer :-).

template() behaviour change in 1.3090 (immediately returning)
by David Precious 17 Dec '11

17 Dec '11

Hi all, Starting a new thread for visibility rather than responding in the "bug with multiple "template" calls ?" thread. In 1.3090, template() (and some other keywords, e.g. pass(), halt() etc) now immediately halt execution of the route handler. This made perfect sense for the other keywords affected, but for template(), it seems plenty of people are using template() in undocumented (but not incorrect) ways to generate emails etc, rather than intending the return value of template to be returned by their route handler immediately. Since this is causing problems for people, we're going to reverse this change, better document the behaviour and usage of the template keyword, and get a new release out ASAP. Sorry to those inconvenienced by this change - your complaints have been heard and listened to :) Cheers Dave P -- David Precious ("bigpresh") <davidp(a)preshweb.co.uk> http://www.preshweb.co.uk/ www.preshweb.co.uk/twitter www.preshweb.co.uk/linkedin www.preshweb.co.uk/facebook www.preshweb.co.uk/cpan www.preshweb.co.uk/github

bug with multiple "template" calls ?
by Assaf Gordon 17 Dec '11

17 Dec '11

Hello, In my dancer application, I'm using "template" to create documents that are not necessarily displayed as HTML (they are message bodies that will be sent with Dancer::Plugin::Email). I have one (or more) calls to "template" to create the email text. and the last "template" creates the HTML page. Conceptual example: ==== get "/hello" => sub { my $name = params->{name}; my $email = params->{email}; ## Email to be sent to the user, NOT rendered as HTML. my $msg = template("email_body", { name => $name }, { layout => undef } ) ; my $subject = template("email_subject", { name => $name }, { layout => undef } ) ; email { message => $msg, subject => $subject, to => $email } ; ## The welcome page, sent back to the user return template("welcome", { name => $name, email => $email } ) ; } ===== With Dancer version 1.3079_3, it worked perfectly. After upgrading to 1.3090, the result of the first template is always returned to the user - what changed ? any ideas/suggestions are welcomed. Thanks, -gordon
