Dancer::Plugin::SimpleCRUD use of template
by Gert van Oss 10 Mar '14

10 Mar '14

Dear Dancers, Enjoying Dancer::Plugin::SimpleCRUD. Really a great tool. Just one thing I'm having a problem with is the use of a template. Is it possible to adjust the view that comes out of the box and where can I find this view? If not then reading the docs it says that: "a template must have a "simple_crud" placeholder defined or you won't get any output. This template must be located in your "views" directory." This maybe should all be obvious but setting up a view with [% render_content %] doesn't work. Should I define all database fields in the template? Thanks, Gert

Changing paths for testing purpose

Hi, I wrote this test: use strict; use warnings; use Test::More; use Test::TCP; use LWP::UserAgent; use FindBin; use t::testapp::lib::Site; BEGIN { $ENV{DANCER_VIEWS} = "views"; } Test::TCP::test_tcp( client => sub { my $port = shift; my $ua = LWP::UserAgent->new; my $res = $ua->get("http://127.0.0.1:$port/admin"); ok($res->is_success); }, server => sub { my $port = shift; use Dancer2; set(show_errors => 1, startup_info => 0, port => $port, logger => 'capture', log => 'debug', ); Site->runner->server->port($port); start; }, ); done_testing; t::testapp::lib::Site is just a dummy app I created as environment to test libraries. Problem is that it search for views in t/testapp/views, but I want it to find them under t/../views. I know that running the test as DANCER_VIEWS=views t/001_app.t it works but how can i force DANCER_VIEWS=views inside the code? I tried $ENV{DANCER_VIEWS} = $other_path but it's not working... Thank you! -- Cymon http://perlishscrewdriver.blogspot.com

Paypal

I recently put Dancer::Plugin::PaypalExpressRoutes on CPAN. This is an interface to Business::PayPal::API::ExpressCheckout, and registers three keywords for completing a transaction: ppsetrequest, ppgetrequest, ppdorequest. For convenience it also registers getppdetails, which gives access to the details hash of customer data returned from the ppgetrequest call, and getppresult which gives access to the results hash of transaction data returned from the final ppdorequest. The documentation contains further details and examples of routes in your site.pm I use it under the Interchange6 plugin, but I suppose it should work under any Dancer app with the appropriate configuration.

permission denied when trying to write_file
by Gert van Oss 04 Mar '14

04 Mar '14

The small app I was creating works ‘perfect’ locally. A folder is scanned for images. The images are listed and a user then can give tags/description to the images. The updates are stored in a ‘yaml-file’ (for now). When deploying it on a server I get: [hit #10]request to POST /edit/0 crashed: write_file 'myImages.yml' - sysopen: Permission denied at... The code of the POST post '/edit/:id' => sub { my $data = get_AoH_imagelist(); my @data = @{$data}; my $id = param('id'); $data[$id]{tags} = params->{tags}; $data[$id]{description} = params->{description}; my $filename = "myImages.yml"; write_file $filename, to_yaml($data); redirect '/data'; }; Just thougth to change the permissions of the file but that didn't work. It has been a long journey. A RESTful service, login with encrypted password. This issue seems to be the last hurdle. Hope someone is able to hint me in a direction to solve this. Thanks, Gert

How to miminise $response->{content} of the 500 error page?
by Иван Бессарабов 03 Mar '14

03 Mar '14

Here is my problem. I'm writing a small Dancer1 app. I'm writing tests to simplify the development. In my code I use a lot of `croak` to die in any unusual situation. Everything works fine, but I have one small thing I hope can be done better. (Actually everyting is working, but I want to make the development a bit more better) My problem is with the test output. In my test I create Dancer::Response object: my $response = dancer_response( GET => '/die' ); and then test if `$response->{content}` contains needed text. In case the `croak` is executed the `$response->{content}` contaings huge html page with 500 error. So, here is what I see when I run the test: https://upload.bessarabov.ru/bessarabov/djXe9Nlm_EnI_TCnPn8sRQjFxKY.png Well, that output contains the error message that I need, but it is in the beginning of the content, and I need to scroll to that content to find out what was the error message: https://upload.bessarabov.ru/bessarabov/hyycVMgrmrC2x5yAbo0GHZt1lG4.png I hope that there is some simple way to simplify the output of tests to make it easier to develop. I was thinking about the solution, the only think that I can imagine is to made Dancer output my custom error page that has nothing but error message. What do you think? Should I try to do this solution or there is some other way to show needed info in test outpur. PS I've created a simple app that shows this problem: https://github.com/bessarabov/DancerTestProblem
