One-off subroutines in Dancer
by J. Bobby Lopez 07 Apr '11

07 Apr '11

I've experienced some oddities using Dancer, and it's likely due to my being a n00b. Just a quick query on whether I should be able to do something like the following without any problems: ====================== use Dancer; get '/' => sub { my $hello = test_sub("Hello World!"); return $hello; }; start; sub test_sub { my $data = shift; return $data; } ====================== If not, what would be the correct way to do the above? Thanks, -Bobby

JSON RPC Client
by J. Bobby Lopez 07 Apr '11

07 Apr '11

Hello, I'm new to dancer, and I'm trying to figure out if Dancer has a built in way of pulling in JSON data from one of it's own routes, or if a module like JSON::RPC::Client is required. I see that Alex Knowles is using that module in his moonfruit.com site, and I'm just curious if that's the "Dancer" way to do it, or if it was Alex's personal preference. Reference: http://blogs.perl.org/users/alex_knowles/2011/03/yet-another-dancer-site.ht… Thanks, -Bobby

[RFC] Change in prefix / before functionality
by Simon Wistow 01 Apr '11

01 Apr '11

I'd really like to be able to do something like this --- >8 --- package MyApp; use MyApp::Secret; prefix 'undef'; before sub { # do something }; package MyApp::Secret; prefix '/secret'; before sub { return unless auth && auth->is_admin; } 1; --- >8 --- Rather than having to have the before sub in the main MyApp do all my auth work (or conditionally load resources or whatever). However at the moment *all* before subs get run no matter what the route is - if I put some warns in the before subs for MyApp and MyApp::Secret I get [78776] core @0.000241> request: GET / from 127.0.0.1 in /Library/Perl/5.10.0/Dancer/Handler.pm l. 51 In the before for MyApp::Secret at lib/MyApp/Secret.pm line 8, <DATA> line 16. In the before for MyApp at lib/MyApp.pm line 9, <DATA> line 16. [78776] core @0.000302> request: GET /secret from 127.0.0.1 in /Library/Perl/5.10.0/Dancer/Handler.pm l. 51 In the before for MyApp::Secret at lib/MyApp/Secret.pm line 8, <DATA> line 16. In the before for MyApp at lib/MyApp.pm line 9, <DATA> line 16. Perhaps a new method called before_prefix (and before_template_prefix) or something to maintain backwards compatibility?

GSoC
by franck 31 Mar '11

31 Mar '11

Hi everybody This year, Dancer could be part of the GSoC via the Perl Foundation. If you are a student interested in Dancer and looking for a project to work on this summer, please contact us :) There is two core dev who are OK in mentoring (sawyer and myself), so feel free to contact us. If you are interested: - we have drafted some ideas on the EPO wiki [1] (search for Dancer), but feel free to offer other ideas - you can also register yourself [2] and submit a proposition - join #dancer (on irc.perl.org) to talk to us. If you need some help to redact a proposition we will be happy to help. There is also #soc-help (still on irc.perl.org) where you can ask for more informations if needed. Thanks!

bug with Dancer::Error
by Nick Knutov 30 Mar '11

30 Mar '11

Hello all, according to http://search.cpan.org/~xsawyerx/Dancer/lib/Dancer/Error.pm I should do Dancer::Response->set($error->render) at the end. But the 'set' method is not defined in Dancer::Response or Dancer:Object. The sample code does not work. -- Best Regards, Nick Knutov http://knutov.com ICQ: 272873706 Voice: +7-904-84-23-130

complex form building
by WK 29 Mar '11

29 Mar '11

Terr! At the beginning i'd like to thank you all of Dancer developers. I really like to Dance (despite i know too few steps so far) and as readed over whole list archive, it is so good to see which huge improvement is done during the last year. I have an old app, CGI.pm based, fully handy-crafted, designed 1998 as my first Big solution and during all these years i hacked it as far as it needed. I'd like to write it up from scratch again, using Dancer. I looking Mates for this dance and i'd like to find matching ones. One problem is *form building*. I looked sawyer x Spark-presentation (http://sck.to/TW) and if i got it right, nested forms may be right step for me. Still, i'd like to read opinions of yours, from your knowledge and experience. I asked help also in StackOverflow (http://sck.to/O5) and i paste same question here. Maybe my wording is too foggy, so, please ask, i'll try to explain. ---- I'm experimenting with Dancer some time, and looking for the right blocks to build my application. Frameworks tend to have flat example applications, dealing with one table at time. So I have no good idea which tools should be used to build a little bit more complex CRUD forms. Let's say I create a Booklovers app. It should have a form to add/edit books with authors. To cover this I need 3 tables in our database: books, authors and books_to_authors. Which is best way to build a form to add a book with authors? Note: * It is not known how many authors a book may have, we need dynamic adding of rows. * The authors table may have tens of thousands of records, so a select form element is not suitable. * An author may be missing from our database, we need to add them dynamically, too. All these dynamic parts needs some AJAX. Is there a good solution to integrate it with form creating tools in Perl? I looked at CGI::FormBuilder and am still looking, but I did not find something that could build forms for 3 joined tables (many-to-many) as described. The dynamic client-side part also still needs to be covered. Are there some best practices for such a pretty simple case? ---- TIA Btw, one of most important things of choosing Dancer was Unicode support. I am so tired of tools, frameworks, orm-s, libraries, anything which don't support utf-8 in a simple, clean way :) It is really important to support utf-8 on 2011! -- Wbr Kõike hääd, Gunnar

How to select a specific environment when I do "make test"
by Geistteufel 28 Mar '11

28 Mar '11

Hi, I want to switch to "testing" environment when I call "make test". In fact generally I need 3 environments. Production, Development and Testing. Production, should be use directly from plackup or apache. Development, during dev process, And Testing, when I call "make test", it create a db test, load everything like fixture, and don't mess up development environment. Any idea ? I can do DANCER_ENVIRONMENT=test perl Makefile.PL DANCER_ENVIRONMENT=test make test But is they a better way to do this ?

Dancer::Config::load called twice?
by Alex C 28 Mar '11

28 Mar '11

I was looking through the source files just out of curiosity to see how things work and I have a couple of queries. Dancer::Config->load is called twice, first when Dancer::import is called, then again in Dancer::_start. Why is it necessary to call it the second time? And what is the purpose of these lines in Dancer::Config::load? I think that for a key to be in %$SETTINGS, it's hook must already have been called (via _trigger_hooks). So forcing the hooks to be called again like this seems unnecessary to me. 171 foreach my $key (grep { $setters->{$_} } keys %$SETTINGS) { 172 $setters->{$key}->($key, $SETTINGS->{$key}); 173 } Thanks for info and I'm Sorry for poking around in the internals :) Alex

Structuring Dancer Application
by Forgoselo Fontardion 27 Mar '11

27 Mar '11

Hi to all, I've programmed ten years ago a CGI web page for our company. We've decided to upgrade it, to a moderm framework. I'm starting to develop it with Dancer. Makes easy a lot of things that were dificult. I'm concerned on how we can structure the application. I'd like to divide my application in several files, but I haven't found in the documentation the mode to call diferent packages or modules depending on the route. Best regards, R. Fontardion
