I put all my config into into the .yml files for
models.  My setup look like this:

'Model::myschemas':
  schema_class: 'Schema::db'
  connect_info:
    - 'DBI:mysql:database=mydb;host=localhost'
    - 'xxxxxxxxxx'
    - 'xxxxxxxxxxx'
    - RaiseError: 1
      PrintError: 0
      ShowErrorStatement: 1
      TraceLevel: 0

I'm not sure about Models, but anything you put into a
controller is available via $self->{attr}

'Controller::test':
  attr: onetwothree

then: 

package myapp::Controller::test;

[snip snip]

sub myaction :Local {

 my ($self, $c) = @_;

 $c->log->info($self->{attr}); #onetwothree to log
}

I haven't tested this but I image it would work from
Views and Models as well.  Give it a try.
