It's amazing how little code is needed with Moo and the role. Mostly, it just delegates everything. https://github.com/dagolden/dancer-sessionfactory-memcached/blob/master/lib… David -- David Golden <xdg(a)xdg.me> Take back your inbox! → http://www.bunchmail.com/ Twitter/IRC: @xdg

Trouble in uploading file
by Fotis E. Psomopoulos 01 Aug '13

01 Aug '13

Dear all, I am quite new to Dancer but I am really amazed on how few lines of code I have to write for the same functionality (still exploring though). However, I have hit the following issue: I am trying to upload a file using the following code: put '/upload/:file' => sub { my $upload_dir = "MyApp/UPLOADS"; my $filename = params->{file}; my $uploadedFile = request->upload($filename); debug "My Log 1: " . params->{file}; debug "My Log 2: " . ref($uploadedFile); open ( UPLOADFILE, "$upload_dir/$filename" ) or die "$!"; while ( <UPLOADFILE> ) { print UPLOADFILE; } close UPLOADFILE; return "DONE"; }; The PUT command is done via cURL as follows: curl --upload-file test http://localhost:3000/upload/test DONE The output that I see in the "development dance floor" is the following: [9072] core @0.000341> request: PUT /upload/test from 127.0.0.1 in /Perl/site/lib/Dancer/Handler.pm l. 56 [9072] core @0.002434> [hit #1]Trying to match 'PUT /upload/test' against /^\/upload\/([^\/]+)$/ (generated from '/upload/:file') in /Perl/site/lib/Dancer/Route.pm l. 84 [9072] core @0.004173> [hit #1] --> got 1 in /Perl/site/lib/Dancer/Route.pm l. 102 [9072] core @0.006625> [hit #1] --> named tokens are: file in /Perl/site/lib/Dancer/Route.pm l. 130 [9072] debug @0.009443> [hit #1]My Log 1: test in MyApp\lib/MyApp.pm l. 20 [9072] debug @0.010818> [hit #1]*My Log 2: in MyApp\lib/MyApp.pm l. 21* [9072] core @0.015854> [hit #1]response: 200 in /Perl/site/lib/Dancer/Handler.pm l. 179 The problem is that the file is created with the correct name in the correct folder (MyApp/UPLOADS/test) but it is always empty (0 size). No other warnings or errors, but I do see an issue in the output (marked in bold - 2nd custom debug line). Any ideas? Thank you in advance for your time! Regards, Fotis -- Fotis E.

New Site: The Political Web
by Dave Cross 24 Jul '13

24 Jul '13

Hi, I thought people on the Dancer mailing list would be interested in this. Yesterday I blogged about a new web site I have created. It is, of course, developed using Dancer. It's a web site that tries to make it easier for people in the UK to get information about their MP's. It's called "The Political Web". The blog post: http://perlhacks.com/2013/07/just-build-something/ The web site: http://politicalweb.org.uk/ Cheers, Dave...

Deploying perl dancer app using Plackup and Starman
by Anand Meher 23 Jul '13

23 Jul '13

Dear Dancer Experts, I am trying to deploy my first dancer app using Plackup and Starman. I am using the following commandline as suggested in the perl dancer deployment documentation. "*plackup -E production -s Starman --workers=10 -p 80 -a bin/app.pl*" This command seems to be working only on the same machine (only on localhost), but when I try to access from an another machine, it does not seem to work. I also tried with different ports. The same command without enabling Starman server works, i.e. the command "*plackup -E production -p 80 -a bin/app.pl*" works perfectly. Could you please let me know, if I am missing something when I enable Starman? I am using cygwin on windows machine to deploy the app. Thanks In Advance Regards AMK

Set interface language via URL path
by Pedro Melo 08 Jul '13

08 Jul '13

Hi, I'm being asked to write a webapp for a site that will have three versions for, one for each language. The current idea is to use http://site.tld/en/, http://site.tld/de/ and http://site.tld/fr/. I'll need to think this over on how to do this with Dancer2, but I want to reuse as much as possible of the routes between the three sites. Does anybody did this before and can share a strategy? My current best solution for this would be to had a hook as soon as possible and remove the first level path if it matches one of the languages we support and set a var for it. Any other suggestions? Bye, -- Pedro Melo @pedromelo http://www.simplicidade.org/ xmpp:melo@simplicidade.org mailto:melo@simplicidade.org

Just another dancer
by Feng He 08 Jul '13

08 Jul '13

We game.yy.com have been using dancer to provide the RESTful API for our DNS service. It is simple enough to write the API methods along with the great Perl modules on CPAN, special to the DNS related modules like Net::DNS, Data::Validate::Domain etc. Once the API was running with CGI under Apache, but I swithed them to dancer within just one day. Thanks for the great project.

ajax plugin, serialize a 1D perl array to JSON
by Anand Meher 07 Jul '13

07 Jul '13

Dear dancer experts, I have a 1D Perl array which I would like to encode using JSON and send it as a response to an ajax request. I have implemented the following steps so far in my dancer app: *use Dancer::Plugin::Ajax;* *set serializer => 'JSON';* * * *ajax '/getarray' => sub {* * * * my @sendArray;* * ........... * * {* * @sendArray; # this is the array I intend to send to the client Java Script* * }* * * *};* The sendArray is not a (key, value) pair based structure, but a simple 1D array. Can anyone let me know if * "@sendArray"* statement at the end of ajax routine above will correctly encode to JSON? Also is there any way to print (to console) the final encoded JSON object from the ajax routine at the server end? thanks in advance \amk
