transfer log object
by Arjan Widlak 25 Aug '15

25 Aug '15

Dear all, How can I get the log object? (outside of a specific route) I have this Dancer2 application that is an interface to a backend. If I could handover the Dancer2 log object to the backend, it could write to the same log. What I would like to do is something like: |use Dancer2;|| || ||my $dancer2_log = XXX->get_dancer2_logger;|| || ||my $backend_environment = Backend::Env->new({|| || log => $dancer2_log,|| ||});|||| || ||get '/' => sub {|| || my $env = $env; ... |Is it possible to obtain the log object somehow, or do I have to instantiate Dancer2::Core::Role::Logger myself, and hand it all the config information myself? Kind regards, Arjan.

passing a variable to a new subroutine route
by Richard Reina 24 Aug '15

24 Aug '15

PLEASE IGNORE MY POST SENT MOMENTS AGO. I WAS NOT FINISHED TYPING. I have the following post that gets a user's selection from a page then looks up the corresponding records for the selection and put them into a hash refrence. THat part works fine. How can I then call another page/route with that hash_refrence? For example; post '/mypage' => sub { # let user make a selection my $select_id = params->{Sselect}; print "\n\nLooks Like They Selected No: $select_id\n\n"; # look up DB records corresponding to $select_id; # store them in hash refrence $sel_ref } Now I would like to call template/page sport_add but I would like it to have $sel_ref so that it could put that data into the template sport_add get '/sport_add' => sub { template 'sport_add.tt', { 'MyTypes' => $sel_ref, # 'Testing' => "This is text to test to make sure this will come through", # to test, use this like <% Testing %> on your template page }, {}; }; Thanks for any help. Have a great afternoon.

Accepting JSON in a POST request
by Gabor Szabo 24 Aug '15

24 Aug '15

Hi, When I send a POST request with JQuery or with a plan HTML form I see 'CONTENT_TYPE' => 'application/x-www-form-urlencoded; charset=UTF-8', and the data looks like this: 'body' => 'foo=23&bar=19', If I understand it correctly then this is what Dancer turns into the values accessible via param() When I use Angular to send a POST request to the Dancer back-end, by default it send 'CONTENT_TYPE' => 'application/json;charset=UTF-8', and the data looks like this: 'body' => '{"foo":23,"bar":19}', and Dancer2 does not parse this. Shouldn't Dancer2 look at the content type of the POST request and handle the data accordingly? Or is that the job of PSGI? Do I need to tell something to Dancer2 or to PSGI to do this? regards Gabor

Does dancer have a post-return hook or something of that nature?
by Robert Smith 24 Aug '15

24 Aug '15

Here’s what I want to do: post '/info' => sub { info "\n\n\tIn /info with params:\n" . Dumper params; my $tmp_href = params; if (&do_some_stuff_here($tmp_href)) { $tmp_href->{status_code} = "200"; } return $tmp_href; # THEN DO SOME POST RETURN STUFF HERE (Obviously not here, but somehow a callback function for post-return or something like that?) }; Does it exist? I feel like I’ve been through the documentation pretty thoroughly. -Robert

How to data into webpage
by Richard Reina 21 Aug '15

21 Aug '15

Have been learning Dancer2 over the last few weeks and really like it. Wondering if someone can tell me how I can load data from a MySQL database into a dancer rendered page. I am comfortable writing SQL in perl via perl->DBI just don't have any idea how to bring the data from a fetch into a webpage so that I can display it directly on the page or load it into a dropdown menu. Any help is greatly appreciated. Thanks

Dancer2 Cookie Expiry Question
by David H 20 Aug '15

20 Aug '15

Hi All, I've tried setting my own cookie with Dancer2 and also setting the session engine as Cookie. I'm using Windows 32 Bit (under Cygwin), with Perl 5.22 Dancer2::Session::Cookie - 0.006 Dancer2 - 0.0161000 Dancer2::Core::Cookie - 0.16000 Although I couldn't find a lot on the Dancer2 method, there is a bit on how to do this with Dancer1. I have this in my config.yml (thanks Andrew for the help with this): template: "template_toolkit" session: Cookie engines: template: template_toolkit: start_tag: '<%' end_tag: '%>' session: Cookie: secret_key: mykey default_duration: 60480064 However when the session is created, as per this image below, the session expiry is still 'session' instead of the time I set, which should be roughly. [image: Inline image 1] Any help would be appreciated, even if I could create another session and set the expiry or something but it all seems to point to something from config.yml not being set in the session. I've had a look at the cookie tests but I still can't figure out how to work with cookies properly in Dancer2. The date I set should set the session cookie to around 2130. I've also tried lower times with no effect. Thanks a lot, David

What is the status of plugin architecture rewrite?
by arjan 20 Aug '15

20 Aug '15

Dear all, In some github discussions a redo of Dancer2 plugin architecture is given as a reason why certain plugins do not work and are not fixed. I found out with Dancer2::Plugin::Auth::Extensible::Provider::Database, but the discussion suggests it's a more general problem with plugins that call plugins. These are discussions of March, April of this year. What is the status of this redo? How come this development work is on cpan, while it breaks plugins, but is also not in a state the plugin can be updated? I'm quite new to Dancer2. What should I know of the development cycle when I use Dancer2?

Dancer2 Basic YAML question
by David H 19 Aug '15

19 Aug '15

Hi All, I've put this into a config.yml file and it isn't working really at all and I'm guessing there is something basic going on that I don't know about. template: "template_toolkit" engines: template: template_toolkit: start_tag: '<%' end_tag: '%>' session: Cookie engines: session: Cookie: secret_key: yoursecretpassphrase default_duration: 604800 When I put in the session: Cookie line after the template toolkit line, it gives me an error about not having a secret_key. When I put the section before it, it just return <% content %> on every page, presumably because something is failing after the cookie section or my .yml formatting is completely wrong... Can I please have some pointers as to where exactly I'm going wrong here? Thanks in advance, David
