26 Mar '11

Hi, Well I have a layout main which include my template. My index.tt is huge and I want to split it into many partial file. I want to do something like this : <div> <div class="tabs" <% INCLUDE tabs %> </div> <% INCLUDE shorten %> <% INCLUDE sidebar %> </div> ... well instead of having one huge index file. How can I do that ? I have try but Template tell me that "tabs" is missing.

Handling file uploads
by Stefan Oberwahrenbrock 25 Mar '11

25 Mar '11

Hello! I have some trouble handling file uploads with my first dancer app. Maybe someone can point me in the right direction: To get hold of an uploaded file sent via PUT, I have set up this route handler: put '/upload/:file' => sub { my $upload = upload( params->{file} ); debug "My Log 1: " . params->{file}; debug "My Log 2: " . ref($upload); }; To test the handler, I feed it with some data sent by "curl": curl --upload-file /srv/mydata.tar.gz http://localhost:3000/upload/ As far as I understand the documentation, $upload should hold a reference to an object of typ Dancer::Request::Upload now. Thus, methods like "filename", "basename", "tempname" etc. should be accessible. The logfile looks quite good - at the beginning: [3432] debug @0.003234> [hit #1] trying to match `/upload/mydata.tar.gz' against /^\/upload\/([^\/]+)$/ in /usr/local/share/perl/5.10.0/Dancer/Route.pm l. 73 [3432] debug @0.003493> [hit #1] My Log 1: mydata.tar.gz in lib/mywebapp.pm l. 26 But the next line indicates, that $upload is not what I expect it to be: [3432] debug @0.003550> [hit #1] My Log 2: in lib/mywebapp.pm l. 27 In addition to that, calling one of methods mentioned above (e. g. "$upload->filename()" ), produces a runtime error: Can't call method filename on an undefined value at... Probably I have not understood the upload() subroutine correctly - any hint is welcome!

trouble with sessions
by Mr. Puneet Kishor 25 Mar '11

25 Mar '11

Suddenly, out of the blue today, my web site is broken because of sessions problem. I have been using Dancer::Sessions::SQLite, something that I had coded, and that had worked just fine for months until today. Today I start getting the following error { "error" : "DBD::SQLite::st execute failed: constraint failed\nsessions.id may not be NULL at /usr/local/lib/perl5/site_perl/5.12.1/Dancer/Session/SQLite.pm line 159.\n" } The offending line is 142> sub flush { 143> my $self = shift; 144> 145> my $sth; 146> if (session_db($self->id)) { 147> $sth = $dbh->prepare(qq{ 148> UPDATE sessions 149> SET a_session = ? 150> WHERE id = ? 151> }); 152> } 153> else { 154> $sth = $dbh->prepare(qq{ 155> INSERT INTO sessions (a_session, id) 156> VALUES (?, ?) 157> }); 158> } 159> $sth->execute(Storable::freeze($self), $self->id); 160> 161> return $self; 162> } Seems like $self->id is not generating a session id. So, while I try and figure out what is going on, I thought I would switch to the factory-provided Dancer::Session::Storable. However, with that I get the following error { "error" : "Warning caught during route execution: Use of uninitialized value $id in concatenation (.) or string at /usr/local/lib/perl5/site_perl/5.12.1/Dancer/Session/Storable.pm line 57.\n" } The offending line is 55> sub session_file { 56> my ($id) = @_; 57> return path(setting('session_dir'), "session_$id.stor"); 58> } Hmmmm... once again, no $id. So, what is going on, and how do I fix this? The only thing new that I can think is that I upgraded to Dancer 1.3020 a couple of days ago. Although, I could have sworn that the web site was working fine even after upgrading, but I guess I should swear. Any help would be much appreciated.. this is a tight spot. Puneet.

freeze devel before doing a stable release ?
by damien krotkine 24 Mar '11

24 Mar '11

Hi, I had a chat with sawyer about the difficulties of releasing a stable release : 1.3020 was supposed to be just a release of 1.3019, renamed to be released as a stable version. But meanwhile, more development occured in the devel branch, so when sawyer released 1.3020, the git graph were screwed. He should have do some rebasing magic, etc, to be sure it would still be 1.3019... Tricky stuff. And so he mentioned an idea : freeze devel while we release stable. I know it sounds like old history, when Dancer was frozen for months, waiting for the next stable release, and all development on hold. But here it should be different : we could agree to freeze devel for a maximum of X days (X being 5 or 7). If the stable release has not been achieved in this "frozen window", then too bad, we'll retry later. And we could say that we shouldn't freeze devel more than once in a month, or once in 2 months for instance ? So I'm just throwing Sawyer's ideas + some of mines, so that we can cool down a bit the release process, which seems to be too hot currently. What do you think ? All this because of the huge amount of contributions, which is a good sign :) dams

Help with github, please
by Brian E. Lozier 23 Mar '11

23 Mar '11

I wrote a tiny patch and I want to make a pull request on github. I'm confused as to how I'm supposed to be doing this because of a few things, but now mostly because I don't know how github works. Originally I used the fork button on github to fork the Dancer project. That got me "master" I think. I made a change, committed it, pushed it back to the server, and then issued a pull request. This was a month ago or so. Then xsawyerx notified me that the pull request was approved and all was well until now when I have another patch. I made another patch on my same branch and issued another pull request, but it pulled in again the original change I had made, so it looks like it didn't detect (somehow, I'm not sure how this is supposed to work) that my original change had already been pulled in. So I deleted my fork of the Dancer repo and started again with a new fork. I tried to follow the instructions here: http://help.github.com/fork-a-repo/ on forking and doing pull requests. After I forked I cloned to my local machine and then followed the instructions on "git remote add upstream" that would supposedly "track upstream" which I don't quite understand. When I did that it put me in the "devel" branch and my "master" branch disappeared. When I do git branch I get this list: * devel And that's it... So I checked in my change and pushed this *devel branch and I want to do a pull request. Is this correct? What happens when/if my change is accepted? How do I make github not include it on the next pull request? If I am doing something wrong please correct me. As you can tell I'm not very familiar with git and github (although I've been using cvs and svn for a really long time). Thanks, Brian

Apache Configuration for Directory
by Ogden 22 Mar '11

22 Mar '11

Thank you so much for an awesome framework as Dancer! I am converting all my HTML::Mason apps to Dancer and wanted to mess with one. Within Dancer::Deployment, I know I can put the app in place for a whole domain but how about for just a directory, say site/beta. I have the following config: <Directory /usr/local/apache/htdocs/domain.org/beta/> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all AddHandler fastcgi-script .fcgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule (.*) public/dispatch.fcgi/$1 [L] </Directory> This works for the pages I call, such as http://domain/beta/, however, for files in the public directory, such as http://domain/beta/css/style.css only work when called as http://domain/beta/public/css/style.css . In other words, public directory does not seem to be called by the app. I could do: Alias /beta/css /usr/local/apache/htdocs/domain.org/beta/public/css Alias /beta/images /usr/local/apache/htdocs/domain.org/beta/public/images But this seems like a hacky work around. Thank you very much Ogden
