I18n for Dancer Applications
by ambs 26 Jan '11

26 Jan '11

Hello, Is there any plugin already developed for i18n of dancer applications? Or anybody working on such a thing? I have a few ideas of what I would like, but not sure I am able to implement it (yet). Meanwhile, sukria, where did you put that dancer background? Can't find it under Dancer webpage :) Cheers ambs

Fwiw, I can't get slides.dancer.org work in Safari. I go to the web site, and just can't get the page to forward no matter what I try. -- Puneet Kishor

why does "warn" fail?
by Brian E. Lozier 25 Jan '11

25 Jan '11

As a perl veteran I am used to using the built-in "warn" function to write to STDERR. Under mod_perl/Apache this prints to the web server's error log. Using my dancer app like this: plackup -L Shotgun app.pl If I have a "warn" anywhere in my app, I get an error message: Error trace status code needs to be an integer greater than or equal to 100 at /usr/local/lib/perl5/site_perl/5.12.2/Plack/Middleware/StackTrace.pm line 27 However, if I print STDERR "msg"; that works. My question is: what happened to warn? Can it be fixed so that it writes to STDERR instead of triggering an error message? I know about the "warning" function but it's really hard to change 10 years of muscle memory! Thanks, Brian

I agree with Naveed (where basically discussing a Perl Heroku, .... again) that a personal Dancer VM environment would be best.

Deployment trouble
by Maurice Mengel 20 Jan '11

20 Jan '11

Hi, I have a problem with my dancer webapp deployment. I don't know where to look anymore. I had the old version of my webapp deployed the same way and it worked well. Now, I update it and it doesn't work any more. Dancer is and was version 1.2003. I updated Plack to current version, but no change. I had it in Apache using plack like described in Deployment.pod. Current setup: <VirtualHost 85.xxx.36.140:80> Servername spk.mimo-project.eu DocumentRoot /var/www/vhosts/mimo-project.eu/webapps/Salsa_OAI #SetEnv DANCER_ENVIRONMENT "production" ErrorLog /var/www/vhosts/mimo-project.eu/webapps/logs/error_log CustomLog /var/www/vhosts/mimo-project.eu/webapps/logs/access_log common <Directory /var/www/vhosts/mimo-project.eu/webapps/Salsa_OAI/public> AllowOverride None Order allow,deny Allow from all </Directory> <Location /> SetHandler perl-script PerlHandler Plack::Handler::Apache2 PerlSetVar psgi_app /var/www/vhosts/mimo-project.eu/webapps/Salsa_OAI/bin/app.pl </Location> </VirtualHost> After update, I get a segmentation fault in /var/logs/apache2/error.log (ubuntu) everytime I try to access webapp: [Thu Jan 20 18:20:18 2011] [notice] child pid 32575 exit signal Segmentation fault (11) That's all I get (unless I switch to development environment, as above). The strange thing is that I can run the webapp as standalone, both in production and development environment. I can run it also thru plackup via HTTP::Server::Simple. Somethine else. I changed the httpd.conf file and tried both production and development mode. Debug messages then go to /var/logs/apache2/error.log although I explicitly specify ErrorLog /var/www/vhosts/mimo-project.eu/webapps/logs/error_log I checked my paths a hundred times. The ErrorLog file exists. I also tried to make sure that the permissions work and tried with 777 just to be sure. But why doesn't apache log the errors in the ErrorLog which I gave it? In development mode, I see that my dancer app fails during initialization when it loads the sqlite db. Why would it do so only when started from apache? I hope you have an idea. Thanks Maurice

A Dancer based web site for "every" PM group
by Gabor Szabo 20 Jan '11

20 Jan '11

Hi, here is an idea that might be interesting. There are 250 or so PM groups. pm.org currently only offers static web hosting. If a PM group wants something more interesting they need to put it on another server. What about setting up a server with Dancer and offering the pm groups access to upload the static part of the web site? They will then come with various additional features they might want to have on their web site which will drive requests but which will probably also bring in volunteers to build those features. I would only install any code from CPAN, and let the pm admins only upload configuration file or only upload things via a web interface. This would drive the creation of a Dancer based content management system. What do you think? Gabor -- Gabor Szabo http://szabgab.com/ Perl Ecosystem Group http://perl-ecosystem.org/

Caching headers
by Nick Hibma 19 Jan '11

19 Jan '11

Anyone here have any success adding caching headers to output of Dancer? I've tried using header (as stated in my previous mail), but that only works with the output of TT, not with JSON output. It should be trivial, but somehow the headers are being deleted before the (JSON) page is sent. Nick Hibma AnyWi Technologies P.S.: Rationale: I do data viewing through a javascript app and it relies on caching in the browser of the paged datasets for performance. At the moment I can see that that pages are fetched from the database all the time, which won't work with 25M entries over 2 months 2 ships (will be 1 year over 20 ships soon).

Bug in Dancer with HTTP_HOST
by Peter Gordon 19 Jan '11

19 Jan '11

I am trying to use dancer in standalone mode and testing it locally. I am using Ubuntu with Dancer 1.3000_02 In the screen dump I am seeing the HTTP_HOST variable set as: HTTP_HOST => 'localhost, 127.0.0.1:3000', It is used in Dancer/Request.pm and is used to build the next url, which clearly is incorrect. sub base { my $self = shift; my @env_names = qw( SERVER_NAME HTTP_HOST SERVER_PORT SCRIPT_NAME psgi.url_scheme ); my ($server, $host, $port, $path, $scheme) = @{$self->{env}}{@env_names}; $host =~ s!.*,\s+!! ; #pmg $scheme ||= $self->{'env'}{'PSGI.URL_SCHEME'}; # Windows Peter

using a template to create a JSON structure to send back to an ajax request
by Puneet Kishor 18 Jan '11

As the subject line says, I would like to use a template to create a JSON structure that I would like to send back to the browser in response to an ajax request. Is that possible? Thanks. -- Puneet Kishor Sent with Sparrow
