=head1 NAME
KiokuX::Model - A simple application specific wrapper for L<KiokuDB>.
=head1 SYNOPSIS
# start with the base class:
KiokuX::Model->new( dsn => "bdb:dir=/var/myapp/db" );
# later you can add convenience methods by subclassing:
package MyApp::DB;
use Moose;
extends qw(KiokuX::Model);
sub add_user {
my ( $self, @args ) = @_;
my $user = MyApp::User->new(@args);
$self->txn_do(sub {
$self->insert($user);
});
return $user;
}
# Then just use it like this:
MyApp::DB->new( dsn => "bdb:dir=/var/myapp/db" );
# or automatically using e.g. L<Catalyst::Model::KiokuDB>:
$c->model("kiokudb");
=head1 DESCRIPTION
This base class makes it easy to create L<KiokuDB> database instances in your
application. It provides a standard way to instantiate and use a L<KiokuDB>
object in your apps.
As your app grows you can subclass it and provide additional convenience
methods, without changing the structure of the code, but simply swapping your
subclass for L<KiokuX::Model> in e.g. L<Catalyst::Model::KiokuDB> or whatever
you use to glue it in.
=head1 ATTRIBUTES
=over 4
=item directory
The instantiated directory.
Created using the other attributes at C<BUILD> time.
This attribute has delegations set up for all the methods of the L<KiokuDB>
class.
=item dsn
e.g. C<bdb:dir=root/db>. See L<KiokuDB/connect>.
=item extra_args
Additional arguments to pass to C<connect>.
Can be a hash reference or an array reference.
=item typemap
An optional custom typemap to add. See L<KiokuDB::Typemap> and
