dancer template_toolkit eval_perl config option???
by Matthew Polly 03 Jan '13

03 Jan '13

Happy New Year Dancers, Disregarding whether it is a good idea or not , is there a way to set eval_perl => 1 in Template Toolkit for Dancer? It didn't seem to work in the app config.yml file, which I tried like so: template: template_toolkitengines: template_toolkit: start_tag: '[%' stop_tag: '%]' eval_perl: 1 Even better would be a way to enable it for just one template. For example, would something likemy $template = Template->new( START_TAG => '[%', STOP_TAG => '%]', EVAL_PERL => 1 );fit in a route? How would $template work with respect to the normal 'template' keyword?Thanks for any help!Matt

Outputting binary data
by Rik Brown 02 Jan '13

02 Jan '13

Hi all, If I've got a scalar $data containing some binary data (a JPG image read using read_file($file, binmode => ':raw' ), how can I cause one of my routes to output it? I've done essentially this (simplified): get '/some/route' => sub { my $data = …get_image…; header 'Content-Type' => 'image/jpeg'; return $data; } but this doesn't feel right and causes a broken output (appears to return only a few rows of pixels of the image). Any tips? Cheers -- Rik Brown http://www.rikbrown.co.uk

Dancer::Plugin::Passphrase utf-8 mysql Solved :)
by Wade Burgett 31 Dec '12

31 Dec '12

Thanks for help. After a lot of learning about utf-8, which was quite educational, the problem was simply that I was calling my $result = passphrase('1234')->matches($pin); instead of my $result = passphrase(param('1234'))->matches($pin); doh. -- Wade Burgett el hefe Santeria http://thesanteria.com 503-939-4719

Splat pollution of params' space
by alois.mahdal.1-ndmail＠zxcvb.cz 31 Dec '12

31 Dec '12

Hello dancers! I like Dancer but I'm having a little problem with this regex/wildcard matching. The issue is that hash returned by params() in the relevant sub always contains 'splat' key referring to array of matches. Maybe this reference might be useful (when?), what if I *really* want to pass "splat=splosh"? According to my testing, the value is lost! Can this behavior be disabled? Or is it a bug? (IIUC, I can always do `[ splat ]` so why the pollution?) For illustration, request is: GET /there?splat=splosh&bar=baz and relevant route: get qr{(.*)} => sub { my $params = params(); my ($path) = splat; # '/there' my $foo = $params->{foo}; # 'bar' my $splat = $params->{splat}; # [ '/path' ] instead # of 'splosh'! my $splat = param('splat'); # '/there' } Thanks, aL. -- Alois Mahdal

Dancer::Plugin::Passphrase utf-8 mysql
by Wade Burgett 31 Dec '12

31 Dec '12

Hi peoples, I am back to web-dev after a break to start a restaurant (now coding for the restaurant instead of cooking all the time). Anyway I believe I am having a problem revolving around utf-8 encoding (breaking dbix internals with data going in) - maybe in the way I have the dbic setup. I also suspect that this is something that would cause me bigger problems in the future. Here is the relevant parts of my config.yaml - this would be my first guess as to the source - this is my first dancer project. charset: "UTF-8" # template engine # simple: default and very basic template engine # template_toolkit: TT template: "simple" session: YAML #template: "template_toolkit" ## engines: # template_toolkit: # encoding: 'utf8' # start_tag: '[%' # end_tag: '%]' plugins: Auth::RBAC: credentials: class: SanteriaAuth DBIC: default: dsn: dbi:mysql:Santeria user: root pass: secritpass schema_class: My::Schema options: mysql_enable_utf8: 1 Database: driver: 'mysql' database: 'Santeria' host: 'localhost' port: 3306 username: 'root' password: 'secritpass' connection_check_threshold: 10 dbi_params: RaiseError: 1 AutoCommit: 1 on_connect_do: ["SET NAMES 'utf8'", "SET CHARACTER SET 'utf8'" ] log_queries: 1 Other possible problems: I am running Ubuntu 12.04.1 LTS as my platform - so I would hope to have necessary perl versions, mysql versions to make that work. However I will happily dig in deeper in that area if needed. Maybe a mysql configuration? Any help appreciated - if you live near Portland Oregon I'll buy you a burrito. from here on down may not be necessary reading for someone familiar with the utf8 issues if the stuff above is ok then maybe deeper digging is required. The problem came up when using Dancer::Plugin::Passphrase but I think that this is not relevant to my real problem. I noticed in when I ran this code any '/makehash' => sub{ my $hash = passphrase( param('1234') )->generate_hash; my $user = schema->resultset('SantEmployee')->find(15); $user->pin($hash); $user->update; }; when I try to update the users pin, it crashes dbix internals- Operation "eq": no method found, left argument has no overloaded magic, right argument in overloaded package Dancer::Plugin::Passphrase at /usr/local/share/perl/5.14.2/DBIx/Class/Row.pm line 901, <DATA> line 16. in /usr/local/share/perl/5.14.2/Dancer/Handler.pm l. 98 I can quote the value of hash going into dbix like so $user->pin($hash); but I don't remember doing that in my pre utf-8 days of coding so I am thinking I have mysql taking the data from perl incorrecty. Also when I try to match the passphrase against the pin, it doesn’t match and I really think it should. my $user = schema->resultset('SantEmployee')->find(15); my $pin = $user->pin; my $result = passphrase('1234')->matches($pin); if ($result){print $result}else{print "nomatches $pin"}; <p>nomatches {CRYPT}$2a$04$..XDNZXxKq9/zhpeu4VsbOgXSSonxsoPHX75/kN9H6nvM/oIhhYIWHTTP/1.0 200 OK -- Wade Burgett el hefe Santeria http://thesanteria.com 503-939-4719

auto_page issue
by Rolf Schaufelberger 29 Dec '12

29 Dec '12

Hi, after reading some articles on the dancer advent calendar I started to examine dance in order to see, if I can replace my current MasonX::WebApp application with dancer. So I installed dancer 1.3 , and since I use Mason, I installed Dancer::Template::Mason. Now I found , that auto_page bypasses the template engine by checking, if a specific template exists , and that behavior its still present in Dancer2. In Dancer1 the code in Dancer::Renderer is my $view = Dancer::engine('template')->view($viewpath) || ''; if ($view && -f $view) { and in Dancer 2 in Dancer::Handler::AutoPage my $view_path = $template->view($page); if (! -f $view_path) { In Dancer::Template::Abstract a method "view_exists " exists , so why not use this? For Dancer1 the docs tells, override this function in your template class accordingly. But for auto_page, the template class is not asked if a template exists, and in my opinion, this behavior is not correct. What do you think about this ? Rolf

Route dispatch
by Celogeek 28 Dec '12

28 Dec '12

Can I dispatch my root thought multiple module ? I have in App::Main : hook before => sub { var xxx => "test"; } and in App::Root; get "/" => sub { return vars->{xxx} } But vars seems empty. In my bin/app.psgi I have : use Dancer; use App::Main; use App::Root; start;

OPTIONS route "Your browser sent a request which this web server could not grok."
by Rik Brown 28 Dec '12

28 Dec '12

Hi all, I'm playing with implementing an OPTIONS route. The following code: options '/' => sub { return { something => 1 } } returns this: <html> <head> <title>Bad Request</title> </head> <body> <h1>Bad Request</h1> <p>Your browser sent a request which this web server could not grok.</p> </body> </html> - whereas if the Dancer code is switched to 'get' and a GET is used, it works fine. This request doesn't even seem to be hitting my Dancer app (just running through myapp.pl right now) - no entries in the log, even on 'core' level. Does anyone have any thoughts before I dig further? Cheers, Rik -- Rik Brown http://www.rikbrown.co.uk

Dancer->VERSION comparison issue
by Celogeek 28 Dec '12

28 Dec '12

Hi, I'm still working on upgrading Dancer::Plugin::Redis. And the think I have seen and missing in all module I have look and say compatible with dancer2 is that the 'register' pass 'DSL' as a first args ! so I need to be backward compatible to do that : register redis => sub { shift if dancer_version >= 1.99 ... } But it failed because 1.9999_02 is not numeric ! so I use the "ge" but it is not very great.

Dancer::Test issues
by Celogeek 28 Dec '12

28 Dec '12

I'm trying (hardly trying) to upgrade Dancer::Plugin::Redis. And I face to multiple issues. First, the test unit doesn't work like before. Which complicate the test. For example : use Dancer::Test; use TestApp; dancer_response 'GET' => '/' => lead to 404 but it was working in Dancer1. So I need to do : use TestApp; use Dancer::Test 'TestApp'; dancer_response 'GET' => '/' => 200 But if I test this with Dancer1 I have a warning message : Odd number of assignement in Dancer::Test ... So the Dancer::Test is not backward compatible, and work differently. How can I fix this ?
