Subdirectory support?
by Mariusz Wojcik 05 Jun '12

05 Jun '12

Hey all, Does anyone know how to get Dancer in a subdirectory of an apache webserver with fastcgi? Because Dancer always says the page isn't found. However it works when I install Dancer on the Document Root. I would be thankful for your help. Greets, Mariusz Wojcik

Specifying host for the built in simple server
by Puneet Kishor 04 Jun '12

04 Jun '12

HTTP::Simple::Server::PSGI does support specifying --host, but Dancer responded with not understanding the --host switch. Is there a way I can specify a host other than 127.0.0.1 when launching the simple, built-in web server via bin/app.pl? -- Puneet Kishor

File extension
by Alex 04 Jun '12

Hi all! I have a question about Dancer::Request::Upload. http://search.cpan.org/~xsawyerx/Dancer-1.3095/lib/Dancer/Request/Upload.pm Quote: “ tempname Returns the name of the temporary file the data has been saved to. This will be in e.g. /tmp, and given a random name, with no file extension..” This is my code: post '/upload/:token' => sub { return to_dumper(request->upload('file')); } This is the result: $VAR1 = bless( { 'headers' => { 'Content-Type' => 'image/png', 'Content-Disposition' => 'form-data; name="file"; filename="2.png"' }, 'filename' => '2.png', 'tempname' => '/tmp/QBVx5KfQtB.png', 'size' => '33116' }, 'Dancer::Request::Upload' ); Why does 'tempname' have file extension ?

Strange errors while running multiple dancer apps with mount
by Gurunandan Bhat 04 Jun '12

04 Jun '12

I have 2 applications that work fine when run individually. One uses sessions (Storable) and the other does not use sessions at all. When mounted as recommended in Dancer::Deployment<https://metacpan.org/module/Dancer::Deployment#Running-multiple-apps-with-P…> however, I get strange errors depending on the sequence that I visit the two applications. app1 does not use sessions and app2 uses sessions (Storable) My app.psgi can be viewed here: http://pastie.org/4004017 Here is what I find: 1. When I visit http://localhost:5000/app1 first and then http://localhost:5000/app2. app2 dies with an error: "core - Must specify session engine in settings prior to using 'session' keyword at...". The Settings section in the Debug panel shows no session related settings even though they are present in config.yml 2. When I visit http://localhost:5000/app2 and then http://localhost:5000/app1, app2 dies again but with a different error: "core - template - file error - signin_header.tt: not found at...". signin_header.tt is used in the index template using [% INCLUDE....%] directive of TT. This time, the session related settings are correctly displayed in the debug panel 3. When I visit app2, then app1, then back to app2, I get the session error described in item 1. 4. Sometimes, and this is random, app2 (the one that uses sessions) also loses the value of the database configuration parameters (I use Dancer::Plugin::Database) giving me a "...database not defined..." error. But this is once in about 8-10 visits. Situations 1, 2 and 3 however play out each time. It appears to me that if two apps one using sessions and the other not, then visiting the application that does not use sessions somehow deletes the session settings of the other application. I can easily fix the error in item 2 (template not found..) by giving the full path of the template, but I would lose the very advantage that makes hosting multiple apps *without making any change* to their configuration so attractive. I have tried to debug this for a few days and am unable to figure this. Would really appreciate some help/pointers here. Thank you.

Dancer-based forum
by Brian E. Lozier 01 Jun '12

01 Jun '12

https://github.com/saberworks/App-Fan I started working on a forum system for a personal project but it's sort of stalled so I figured I'd put it out in case anyone would find it useful. There is essentially no management interface. You can see it in action at http://nocityofsilverdale.org/ (site is dead, feel free to play around). There are some rudimentary install docs and example configuration for nginx. The docs also list all the required perl modules (and ubuntu packages, if you use ubuntu). It runs on Postgres. Any feedback welcome, although I don't have any plans to work on this in the near future. There are some areas where I'm not using the dancer functions "correctly" because I just can't seem to get used to function_returns_ref->{'foo'} syntax. I've been typing dollar signs for so long I swear my fingers refuse to omit it. Brian

Added options for Dancer::GetOpt
by Ovid 01 Jun '12

01 Jun '12

Hi all, I've recently discovered a problem where I wrote a small daemon to handle a few tasks for my Dancer application. Unfortunately, I need more options beyond the option port, deamon, environment, help, confdir and restart arguments. I've temporary hacked together an solution that let's me do this: perl bin/rtb_deamon.pl --verbose --force --once \ --environment production But it might be nice if someone thought of a *clean* way of allowing extra arguments beyond those hard-coded into Dancer::GetOpt. I can't think of that clean way right now :) Cheers, Ovid -- Live and work overseas - http://www.overseas-exile.com/ Buy the book - http://www.oreilly.com/catalog/perlhks/ Tech blog - http://blogs.perl.org/users/ovid/ Twitter - http://twitter.com/OvidPerl/
