use Perl

I wrote Sledge::Model.

This module is EXPERIMENTAL!

package Sledge::Model;
use strict;
use warnings;
our $VERSION = 0.01;
use Sledge::Exceptions;
 
sub new {
    my ($class, $page) = @_;
    return bless {page => $page}, $class;
}

package Sledge::Model::CDBI;
use strict;
use warnings;
use base 'Sledge::Model';
use UNIVERSAL::require;
 
sub get {
    my ($self, $name) = @_;
    my $cdbi = $self->_get_class;
    my $cdbi_class = "$cdbi\::$name";
    $cdbi_class->use or die $@;
    return $cdbi_class;
}
 
sub _get_class { shift->{page}->config->{cdbi_class} }
 
1;
 
package Sledge::Model::DBIC::Schema;
use strict;
use base qw/Sledge::Model/;
use UNIVERSAL::require;
our $VERSION = '0.01';
 
sub new {
    my $class = shift;
    my $self  = $class->SUPER::new(@_);
    $self->connect;
}
 
sub connect {
    my $self = shift;
    my $schema_class = $self->{page}->config->{schema_class};
    $schema_class->use or die $@;
    return $schema_class->connect($self->{page}->config->datasource);
}

package Sledge::Plugin::Model;

For CDBI.
in your config.yaml:

  cdbi_class: Proj::Data
  datasource:
    - dbi:mysql:proj
    - user
    - passwd

in your controller:

  sub create_model { Sledge::Model::CDBI->new(shift) }
 
  sub dispatch_index {
    my $self = shift;
    my $memo = $self->model->get('Memo')->retrieve_all;
  }

For DBIC::Schema.
in your config.yaml:

  schema_class: Proj::Schema
  datasource:
    - dbi:mysql:proj
    - user
    - passwd

in your controller:

  sub create_model { Sledge::Model::DBIC::Schema->new(shift) }
 
  sub dispatch_index {
    my $self = shift;
    my $memo = $self->model->resultset('Hoge')->search({});
  }
