The idea is that you can have full control as to what you return to the browser. For example, you might want to return only some simple plain text, or maybe send a file to the browser, in which case wrapping in the main layout would break things. If you use the "template" keyword, then the chances are you're displaying a standard web page, in which case it will be helpfully be wrapped in your main template, as that's probably what you would want. > For example, at following code, why main.tt is loaded at login page (get > '/login') but not loaded at Home Page (get '/' )? > > get '/' => sub { return "Home Page"; }; Here you're returning only the content "home page". If you want the text to be wrapped in the layout, then you will need to put it in a template and use the template keyword. The short of it is that whatever you return from your route is what gets sent to the browser. The layout is just a part of the template functionality which you can use to return web pages. Andy

Session management
by Zahir Lalani 21 May '15

21 May '15

Hi I am wondering if anyone has a specific pattern they use for session data. The issue we are already having is that developers are adding session data in the controller layer, but since we have some 20 controllers, session data is managed across these modules. However, the question now comes as to how we now what our session store looks like overall – the danger being one developer will create a duplicate store in the session. I thought of creating a Moo object which is then self-documenting, and would push this into the session but realised you are then pushing a large block of data each time rather than just the few values a particular module needs. How are others dealing with documenting the data in a session? Z

Main Layout Loading
by Kadir Beyazlı 21 May '15

21 May '15

Hi All, My question may be simple so sorry for it from the beginning. I set layout 'main' at config.yml file as follow: *layout: "main"* main.tt is loaded if I use a template at my code. What is the reason main.tt is not loaded if I don't use a template? For example, at following code, why main.tt is loaded at login page *(get '/login') * but not loaded at *Home Page (**get '/' )*? *get '/' => sub { return "Home Page"; }; get '/login' => sub { # Display a login page; the original URL they requested is available as # param('requested_path'), so could be put in a hidden field in the formtemplate 'login', { path => param('requested_path') };};* I could not find a logic explanation for it. -- *Kadir BeyazlıComputer Engineer* *GSM : +90 535 821 50 00*

dancer2 404 not working?
by Andrew Solomon 18 May '15

18 May '15

Hello Dancer2 experts Following these instructions https://metacpan.org/pod/distribution/Dancer2/script/dancer2 I've just run dancer2 gen -a MyWeb::App and it works as expected but or both Dancer2 v0.159003 and v0.160001 calling a non-existent url on the server does not access the 404.html page - instead it prints out something like Error 404 - Not Found /sdfsdf Powered by Dancer2 <http://perldancer.org/> 0.160001 I can confirm that it worked correctly with v0.09. Is this a known issue or should I raise a ticket? Andrew

Trouble with DBIC in Plugins
by Matthew Mallard 04 May '15

04 May '15

Hi, I’m getting a bit confused with plugins. I’m sure that I was able to use the DBIC Plugin at one point from one of my plugins, but I can’t seem to get it to work in 0.159002 or 0.160000. DBIC seems to be okay outside of plugins. 3 questions: * why does it complain about "Plugin calls 'dsl' instead of '$dsl->dsl’" when I appear to be using '$dsl->dsl’? * how do I get DBIC to print the SQL it’s executing so I can double check it’s what I’m expecting? * am I doing something else wrong in the way I’m trying to use DBIC? Basically this is the code in my plugin: register get_topics => sub { my $dsl = shift; my $type = shift; my $application = shift; my $pageid = shift; my $dberr = 0; my $current; my $urlref; my $template = ""; my $id; my @topics; $dsl->debug( "**** Here 1 ****"); eval { @topics = $dsl->schema->resultset('ContentType')->search({ application => $application }, { prefetch => [ 'content_type_names' ], order_by => 'sort_order' }) }; $dberr += $dsl->check_db_result( $dsl, $@, __LINE__ ); $dsl->debug( "**** Here 2 **** " . @topics); etc, etc } The output in the console is this: [Routes:37674] core @2015-04-27 21:57:16> Entering hook core.app.before_request in (eval 87) l. 1 [Routes:37674] debug @2015-04-27 21:57:16> **** Here 1 **** in /code/Dancer/MediBase/bin/../lib/QTechLib/Plugin.pm l. 31 DEPRECATED: QTechLib::Plugin calls 'dsl' instead of '$dsl->dsl'. at /perf/perl/lib/perl5/Dancer2/Plugin/DBIC.pm line 13.

SendFile
by Zahir Lalani 03 May '15

03 May '15

Hi >From what I can tell, sendfile uses the psgi layer to stream the file. So presumably it still ties up a web worker (e.g. starman)? Has anyone thought of adding the ability for sendfile to utilise xsendfile so that it can be totally offloaded to the proxy web server? Z

Which plugin do you use?
by Gabor Szabo 03 May '15

03 May '15

Hi, I am creating a list of Dancer/Dancer2 plugins that are used. It can't be really scientific, but probably better than nothing. Could you please send me a list of Dancer or Dancer2 plugins you use in your projects? I'll publish the aggregate. Private e-mail is good, I won't include your name in the report, unless you say "it is ok to include me and/or my company name in the report". regards Gabor

How do I call a script from a template?
by John J. McDermott, CPLP 01 May '15

01 May '15

In a template I invoke (successfully) from a Dancer2 path I have some jquery that works outside Dancer2: $.post('/data1.pl',data,function(returnData){ $('#func').html(returnData) This code calls data1.pl and stuff its output into the div func. I know data1.pl works in a non-Dancer2 environment. But I cannot figure out where to put data1.pl so it can be run from the template. I tried just putting it in the dancer public (where the css folder, dispatch.cgi and such are), but that didn't work. I tried even to run it from the browser command line and the browser wants to download it. The directory has +ExecCGI and Dancer2 runs. Where should I put this file and what must I do so I can run it? Thanks! --john -- John J.

Dancer + objects + database
by Juan José 'Peco' San Martín 01 May '15

01 May '15

Hello all, First, thank you for this awesome work! I have a Dancer application that uses Apache + Plack::Handler to run it. Currently, inside each Dancer route I'm forced to create the master object of the application (i.e $object=Myapp->new(-login=>$login)) that it's a huge structure, including the database handler. So: /route1 => creates the $object, reconnects to the database /route2 => creates the $object, reconnects to the database Yep, doesn't make sense... Is there a way to make the $object persistent (and the database connection with it)? Is this related to how the application is running (CGI)? Thank you! Peco
