messed up routes
by Mr. Puneet Kishor 12 Nov '11

12 Nov '11

as much as I love Dancer, and I really truly do... as I said when I first used Dancer, it is a breath of fresh air in the world of Perl, Dancer has become really, really unreliable for me. The biggest problem that I face with it is the unreliable way I seem to get routes and layouts delivered to the browser. In my last email to this forum, I noted that I would get different layout than was expected. Today I decided to do a little experimentation. My routes are like so get '/video/:page_name/:movie' => sub { .. debug "using layout main_video"; layout 'main_video'; template 'video_mov', \%template_opts; }; get '/present/:page_name' => sub { .. debug "using layout main_presentation"; layout 'main_presentation'; template 'presentation_slides', \%template_opts; }; get '/*?' => sub { .. debug "using layout main"; template 'index', \%template_opts; } In my layouts I have also embedded debug strings like so    Yet, when I go to a page that should be using the layout main, my log file says [88056] debug @0.001454> [hit #14]using layout main in .. yet, I can see using "View source" in the browser  This is random, and it makes absolutely no sense. I would love to see this resolved, because, partly, I really, really love using Dancer. And, partly, I am sure there is nothing out there that is as easy and pleasurable to use. I shudder at the thought of going back to CGI::App, but I also can't let this unreliability continue. Suggestions? I am serving about 10 or 12 different apps using Starman proxied behind Apache2, if that is any help. -- Puneet Kishor

Dancer 2 supports sessions
by Alexis Sukrieh 12 Nov '11

12 Nov '11

Hello fellow Dancers! I'm glad to announce that the prototype for Dancer 2 now supports sessions (the YAML session engine is provided and works as expected). So I'd be very happy if you coudl send me upgrade reports of your existign apps (you should be able to run any Dancer 1 app with Dancer 2 now, as long as it doesnt use a plugin that gets into Dancer's core. As usal, to get the code of Dancer 2, go on GitHub: https://github.com/sukria/dancer2 Also, to run the test, you should use the template engine "TemplateToolkit" and the session engine "YAML". You might also need to tweak a bit your config files like the following: in Dancer 1: engines: template_toolkit: ... in Dancer 2: engines: template: template_toolkit: ... Also note that the default start/end tags of TemplateToolkit are back to TT's default in Dancer 2 ([% and %]). Thanks a lot!

run in production on shared hosting
by Nick Knutov 12 Nov '11

Hello, what is the best way to run (a lot of) Dancer apps in production on shared hosting now? I'm the owner and main developer at small hosting company and want to create the environment that allows a lot of users to quick run a lot of Dancer apps. I read Dancer::Deployment but didn't decide anything - Ubic and daemontools don't looks good way (and Ubic at least requires access to /etc), CGI is slow. As for now I do manually something like plackup -E production -s Starman --workers=4 -l /home/$user/tmp/$app.sock -a bin/app.pl & (and I use nginx before app) but it is not easy to start/stop and monitor such apps. -- Best Regards, Nick Knutov http://knutov.com

Yes, but I'd like not to use apache if it's possible. 12.11.2011 3:46, Richard Simões пишет: > Do you support FastCGI?

Thanks for such a great framework
by Sarah Fuller 11 Nov '11

Hello fellow Dancers! Just wanted to send a quick note to the Dancer community, especially the people contributing to the Dancer project. Thanks to Dancer I've managed to create my very first open source project, ever. Now I'm not a developer so its far from perfect. However the point is I had a lot of fun while working on this little project and I mostly contribute this new found enjoyment to Dancer. Love it! Keep up the great work! :D Kind regards Sarah Fuller https://github.com/averna-syd

Hi Sarah, Looks the same as what I had in regards to the socket, and similar to the one in the deployment pod. I will have to revisit why I couldn't get it to work. Thanks for sharing.

Sarah, Do you have a basic example of nginx and sockets you could share ? I have been unable to get that setup to work, albeit I only spent a small amount of time on it.

Deployment pod
by Assaf Gordon 10 Nov '11

10 Nov '11

Here's my latest draft: https://github.com/agordon/Dancer/blob/topic/deployment_pod/lib/Dancer/Depl… It's pretty much ready (from my narrow Apache point-of-view). 1. I have verified all the different apache configurations - they all work (barring any typos). 2. included is a section on serving static files directly (requested by someone on the mailing list). 3. Added a section on load-balancing in apache using mod_proxy_balancer 4. Elaborated about deploying multiple Dancer applications on same server. 5. Simplified (IMHO) the configuration Stanzas - removed fluff like "ServerName" etc. which is not always relevant. 6. Change some of the Apache configuration examples, the old POD show changing the "documentroot" - that's not needed. 7. with NGINX+Proxy, simplified the example, removed fluff, and made it use TCP socket instead of a unix socket - to be more in line with the other examples. 8. Other stuff - copied as-is. I'm not familiar with those things (e.g. PerlBal, Balance, UBic, etc.) - so proofreading is still required. Comments and corrections are welcomed, -gordon

Testing image upload
by Stephen Fenwick-Paul 09 Nov '11

09 Nov '11

Hi, I've can successfully upload an image from a browser but using the same route in my test suite with this: $response = dancer_response( POST => '/auth/location/1011/image', { params => {}, files => [{name => 'file', filename => "test.png"}] }, ); (taken from the http://search.cpan.org/~xsawyerx/Dancer-1.3080/lib/Dancer/Test.pm) I get the error: "libpng error: PNG file corrupted by ASCII conversion" so I'm guessing the test is missing something that the browser is doing? Any ideas? thanks Stephen
