Re: instantiate objects from non-Catalyst model classes with parameters

[ruoso]

interesting you mention this. I have just wrote a model factory based on Catalyst::Component::InstancePerContext...

package Leilao::Model::Negocio;
use Moose;
extends 'Catalyst::Model';
use namespace::autoclean;
use Module::Find;
use Module::Load;
use Sub::Name;
use Catalyst::Component::InstancePerContext;
use Moose::Meta::Class;

sub BUILD {
    my ($self) = @_;
    my @modules = findallmod 'Leilao::Negocio';
    foreach my $neg (@modules) {
        load $neg;
        (my $mod = $neg) =~ s/^Leilao::Negocio/Leilao::Model::Negocio/
+;
        my $sub = sub {
            my ($self, $c) = @_;
            return $neg->new
              ( #user => $c->user,
                schema => $c->model('DB')->schema );
        };

        my $class = Moose::Meta::Class->create( $mod, superclasses => 
+['Catalyst::Model']);
        $class->add_method(build_per_context_instance => $sub);
        Catalyst::Component::InstancePerContext->meta->apply($class);
    }
}

__PACKAGE__->meta->make_immutable;
1;

This model will use create adapted models for every class in the Leilao::Negocio namespace using Catalyst::Component::InstancePerContext and initializing the classes with arbitrary parameters.
