=head1 NAME

CatalystX::CRUD::Object::RDBO - Rose::DB::Object implementation of CatalystX::CRUD::Object

=head1 SYNOPSIS

 # fetch a row from MyApp::Model::Foo (which isa CatalystX::CRUD::Model)
 my $foo = $c->model('Foo')->fetch( id => 1234 );
 $foo->create;
 $foo->read;
 $foo->update;
 $foo->delete;

=head1 DESCRIPTION

CatalystX::CRUD::Object::RDBO implements the required CRUD methods
of a CatalystX::CRUD::Object subclass. It is intended for use
with CatalystX::CRUD::Model::RDBO.

=head1 METHODS

Only new or overridden methods are documented here.

=head2 load_speculative

Calls load( speculative => 1 ) on the internal delegate() value.

=cut

# convenience methods
sub load_speculative {
    shift->delegate->load( speculative => 1, @_ );
}

=head2 create

Calls delegate->save().

=cut

# required methods
sub create {
    shift->delegate->save(@_);
}

=head2 read

Calls delegate->load(). B<NOTE:> If you need a speculative load,
use load_speculative() instead.

=cut

sub read {

    # because of the abusive way RDBO handles load() internally,
    # must re-assign to delegate afterwards. This fixes esp the issue
    # of passing 'with' => 'rel' to load().

    my $cxcobj = shift;
    my $rdbo   = $cxcobj->delegate;
    $rdbo->load(@_);
    $cxcobj->{delegate} = $rdbo;
    return $cxcobj;
}

=head2 update

Calls delegate->save().

=cut

sub update {
    shift->delegate->save(@_);
}

=head2 delete

Calls delegate->delete(@_).

=cut

sub delete {
    shift->delegate->delete(@_);
}

=head2 is_new

Calls not_found() on the RDBO delegate.

=cut

sub is_new {
    shift->delegate->not_found();
}

=head2 serialize

Returns column/value pairs for RDBO delegate with all DateTime
et al objects serialized to strings.

=cut

sub serialize {
    return decode_json( column_values_as_json( shift->delegate ) );
}
