Plack deployment question
by Deepak Gulati 07 Apr '10

07 Apr '10

Hi Folks, This is more of a Plack/PSGI question, but I am hoping someone here can help. I am using plackup to test app.psgi with Starlet (and occasionally with Starman) server. My CSS files are being served with content-type of text/plain and end up not being interpreted by Firefox or Chrome (I see unstyled content). This doesn't happen when using HTTP::Server::PSGI. Any idea where I can configure the mime types for Starlet or Starman? Thanks, Deepak

Deployment question
by Robert Olson 07 Apr '10

07 Apr '10

I'm starting to try to use Dancer in some apps at my day job; here, we have a bunch of apps that we have hung off an nginx proxy server (some using fcgi, some straight reverse proxy). What distinguishes this that we don't use vhosts for all of them; instead, we distinguish based on a toplevel directory. For instance / foo would be delivered to one machine's fcgi , /bar to some other machine's apache. I'd like to be able to use this mechanism to proxy off to a Dancer standalone server. However, to the instance locally it things stuff is rooted at /, but to the clients it's rooted at /somethingelse. I have tinkered with the prefix directive, which makes the actions work ok, but breaks the stuff under public. And if I generate urls inside the actions (like /something/postme), they are incorrect when used in the proxied context. (I'm not sure if this is an entirely cogent explanation; if not let me know and I'll take another run at it with a concrete example :-). --bob

A few more random issues
by Gabor Szabo 07 Apr '10

07 Apr '10

Hi as I am playing with Dancer I encountered a few more small issues: Could the default template say? Powered by <a href="http://www.perl.org/">Perl</a> <a href="http://perldancer.org/">Dancer</a> Add the following to both the script and the module: # strict and warnings are automatcially on The config.yml could already contain all the configuration entries (maybe commented out) Why is this necessary in Dancer.pm? $AUTHORITY = 'SUKRIA'; What do you think?

Re: [Dancer-users] Using utf-8 data from database and template toolkit

Hi, Does it work for you without DBIx::Class? I did the following: 1. Created a SQLite database: sqlite3 names.sqlite 2. Executed the following SQL sqlite> .read names.sql where names.sql contains: create table names (FirstName varchar(20), LastName varchar(20)); insert into names (FirstName, LastName) values ('Bedřich', 'Smetana'); insert into names (FirstName, LastName) values ('Antonín', 'Dvořák'); insert into names (FirstName, LastName) values ('Fréderyck', 'Chopin'); 3. My mywebapp.pl looks like this (the database names.sqlite is in the folder db under the default mywebapp created by dancer): #!/usr/bin/perl use Dancer; use mywebapp; use Data::Dumper; use Template; use DBI; get '/names/' => sub { my $dbh = DBI->connect("dbi:SQLite:dbname=db/names.sqlite", "", ""); my $sql = "select FirstName, LastName from names"; my $sth = $dbh->prepare($sql); $sth->execute; my $names = $sth->fetchall_arrayref; template 'names' => { 'names' => $names }; }; dance; 4. And my TT2 template looks like this: <table> [% FOREACH n IN names %] <tr> <td>[% n.0 %]</td> <td>[% n.1 %]</td> </tr> [% END %] </table> This setup works for me without any data corruption issues. I am on Mac OS 10.6, with Perl 5.10.0, SQLite3 and Dancer 1.173.

Supporting ; as a separator in querystring
by Deepak Gulati 06 Apr '10

06 Apr '10

Hi Folks, By default dancer supports parsing key-value pairs in a querystring separated by an ampersand - &. Is there a way to get it to working with a semicolon ; as well? e.g. http://localhost/hello?key1=value1;key2=value2 Thanks, Deepak

Debugging and logging
by Gabor Szabo 04 Apr '10

04 Apr '10

Hi, I just started to play with Dancer. I wanted to see what's going on so I wanted to turn on logging. I found I can say at the top of my Dancer script: set logger => 'file'; set log => 'debug'; and then I can add calls to debug "hello"; and see the output with tail -f MYAPP/logs/development.log but I was hoping 1) to see the logging on the console window just after this message: >> Dancer server 25189 listening on http://0.0.0.0:3000 == Entering the development dance floor ... 2) See default debug messages on calling various routes, or missing all routes Can I do these? How? Gabor -- Gabor Szabo http://szabgab.com/

Stand Alone applications using Dancer
by Gabor Szabo 04 Apr '10

04 Apr '10

I would like to create a stand alone application with Dancer. Well actually I'll want to run it on a real web server as well but I also want to let people download it and run it without any setup. What I'd like to do is let people run my script: waltz.pl that would launch the Dancer server and then open the default browser pointing to http://localhost:3000 Has anyone done this already? How could I do this in a portable way? (Mac/Windows/Linux for now) Gabor -- Gabor Szabo http://szabgab.com/

Using utf-8 data from database and template toolkit
by Christian Sánchez 04 Apr '10

04 Apr '10

Hi, I'm using Dancer to make a little application that uses a DBIx::Class scheme of another app written in Catalyst. I want to reuse some templates I've made for that Catalyst app, it works fine, but I have some data in my DB with words like 'Sánchez', 'José', etc, when I show this data in the template it shows something like "S�nchez". I put in my config.yml this: engines: template_toolkit: start_tag: '[%' stop_tag: '%]' encoding: 'utf-8' I try with "encoding" and "ENCODING" in the same way I use it in catalyst. I'm using in the DBIx::Class schema: "UTF8Columns" and : __PACKAGE__->utf8_columns(qw/ciudad nombres apellidos comentarios/); Im using postgresql originally in the Catalyst app, but for this app I want to use sqlite3 for just a couple of this tables, I tried this for both postgresql and sqlite3 but didn't work. Also I put: "use utf8" in my app.pm file. And in main.tt: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> What do you recommend for this? maybe I missing something, I've read the docs but I didn't found something for this. BTW, I like Dancer, great job guys! Regards -- Christian Sánchez Usuario GNU/Linux 234800 Maracay - Venezuela http://g013m.com.ve

another logging issue: where was debug() called?
by Gabor Szabo 02 Apr '10

02 Apr '10

Sorry for this rapid firing of e-mail messages, I'll go to sleep soon.... When I call debug("something") I see it in the logfile as Sat Apr 3 00:57:52 2010 [25581] (debug) something in /home/gabor/perl5/lib/perl5/Dancer.pm l. 77 I think it would be better to print the filename and line number of where I called debug() which is probably a few call-frames before. Or maybe I am just missing the context. Gabor
