Re: Dancer 2 yaml config file (is a hash of hashes ... key collision/clobbering is a common pitfall)

[Anonymous Monk]

Can anyone spot what I'm doing wrong?

looks like you're using yaml instead of code, and its tricking your mind, see https://metacpan.org/pod/distribution/Dancer2/lib/Dancer2/Config.pod#MANIPULATING-SETTINGS-VIA-CODE

Config is a hash, a hash of hashes, meaning there is only one %engines, there can be only one engines

{
    'engines' => {
        'template' => {
            'template_toolkit' => {
                'start_tag' => '<%',
                'end_tag' => '%>',
              },
          },
        'session' => {
            'DBIC' => {
                'user' => '',
                'pass' => '',
                ...
              },
          },
    },
    'template' => 'template_toolkit',
    'session' => 'DBIC',
    ...
}

IMHO, this is one of those pitfalls that shouldn't exist :) Dancer provides so many conveniences, why not a reminder that key are colliding/being clobbered

Ah, ok yes that makes sense, got it working (at last) with:

engines:
 session:
  DBIC:
   dsn: "dbi:Pg:database=dbname"
   schema_class: "xxxx::Schema"
   user: ""
   password: ""
   #resultset:
   id_column: "id"
   data_column: "data"
   
 template:
   template_toolkit:
     start_tag: '<%'
     end_tag:   '%>'

session: "DBIC"
template: "template_toolkit"

Thank you.
