app does not reconnect to database after a while
by WK 12 Jun '12

12 Jun '12

Tere! I have a little intranet app (in development environment with Dancer's webserver), which fails to connect to database, when it is unused some hours. When on morning first user tries to get some page, he gets "before filter error": runtime error An error occured while executing the filter named before: DBD::mysql::db selectrow_array failed: MySQL server has gone away at /usr/local/lib/site_perl/My/Settings.pm line 136. Pointed line contains a query, which executes fine, when database connection is available (read: after restarting app). My app's main module logic is like this: package My; use 5.010; use Dancer ':syntax'; use Dancer::Plugin::Database; use Dancer::Plugin::EscapeHTML; use utf8::all; use My::Settings; use My::Tools; our ($my_settings, $dbh) = (); $dbh ||= database; $my_settings = get_settings('prod'); my $my_tools = My::Tools->new ( dbh => database, settings => $my_settings, ); hook 'before' => sub { $my_settings = get_settings('prod'); }; sub get_settings { my $env = shift; my $my_settings = My::Settings->new ( dbh => $dbh, env => $env, ); return $my_settings->{settings}; } In before hook i ask dynamic settings from database. Is there better way to do this. Or other solutions? TIA! -- Wbr, Kõike hääd, Gunnar

Question about Dancer::Plugin::ValidateTiny
by Forgoselo Fontardion 06 Jun '12

06 Jun '12

Dear dancers, I'm building a web application and need to use some forms. I'm using Dancer::Plugin::ValidateTiny to validate de parameters that the web browser send in every request. It's very easy to use, but I have found a limitation and doesn't know how to overcome it. The form i'm working now is for creating a new user, so it has four fields: username password1 password2 email. I'm doing the usual checking, but i can't find the way to implement the folloging rule: "username" and "password1" can't be equal. Is there a way to do this? Thank you, Fontardion

redirect path is wrong
by Mr. Puneet Kishor 05 Jun '12

05 Jun '12

I have a URI http://server/app/d/geomaps/resource.json I have changed it to http://server/app/d/geomaps/gmna/resource.json In my code, I have put the following get '/resource.:format' { return redirect '/gmna/resource.:format'; }; get '/gmna/resource.:format' => { .. }; But the above fails. One, the redirect doesn't seem to recognize and carry the .:format through (if I call resource.json, the program complains that '/gmna/resource.:format' wasn't found). Second, it doesn't prefix the /app/d/geomaps part to the redirected URI. How can I fix this? -- Puneet Kishor

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

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.
