[Catalyst] Some guidance needed please

[Ian Docherty]

My application has (effectively, subject to some cut and paste) the 
following.

################

package MyApp::Schema;

use strict;
use warning;

use base qw(DBIx::Class::Schema);

__PACKAGE__->load_classes(qw(
    UsedPassword
));
1;

################

package MyApp::Schema::UsedPassword;

use strict;
use warning;

use base qw(DBIx::Class);

__PACKAGE__->load_components(qw(PK::Auto Core));
__PACKAGE__->table('used_password');
__PACKAGE__->add_columns(qw(id user password));
__PACKAGE__->set_primary_key('id');

sub create_limited {
    my ($self, $user, $password) = @_;
    
    # password checking logic here
}
1;

################

package MyApp::Model::DBIC;

use strict;
use warning;

use base qw(Catalyst::Model::DBIC::Schema);

__PACKAGE__->config(
    schema_class    => 'MyApp::Schema',
    connect_info => [
        MyApp->config->{db},
        MyApp->config->{db_user},
        MyApp->config->{db_password},
        {AutoCommit => 1, quote_char => '`', name_sep => '.'},
    ]);
1;

################

As I mentioned, if I try to do a call to 
$c->model('DBIC::UsedPassword')->create_limited( ... ); I get the fatal 
error

Can't locate object method "create_limited" via package 
"DBIx::Class::ResultSet

Which is why I think this is not the approach, unless you know otherwise?

Ian
