NAME

HTML::FormHandler::TraitFor::DBICFields

SYNOPSIS

This is a role to pull fields from a DBIx::Class result source. Requires existence of a 'source' attribute.

This feature is new. It doesn't handle relationships yet, and the interfaces are still subject to change.

my $form = HTML::FormHandler::Model::DBIC->new_with_traits(
    traits => ['HTML::FormHandler::TraitFor::DBICFields'],
    item => $book
);

for my $rel( $source->relationships ) {
    next if grep { $_ eq $rel } @exclude;
    next if grep { $_->[1] eq $rel } $self->m2m_for_class($class);
    my $info = $source->relationship_info($rel);
    push @exclude, get_self_cols( $info->{cond} );
    my $rel_class = _strip_class( $info->{class} );
    my $elem_conf;
    if ( ! ( $info->{attrs}{accessor} eq 'multi' ) ) {
        push @fields, "has_field '$rel' => ( type => 'Select', );"
    }
    elsif( $level < 1 ) {
        my @new_exclude = get_foreign_cols ( $info->{cond} );
        my $config = $self->get_fields ( $rel_class, 1, );
        my $target_class = $rel_class;
        $target_class = $self->class_prefix . '::' . $rel_class if $self->class_prefix;
        $config->{class} = $target_class;
        $config->{name} = $rel;
#           $self->set_field_class_data( $target_class => $config ) if !$self->exists_field_class( $target_class );
        my $field_def = '';
#           if( defined $self->style && $self->style eq 'single' ){
#               $field_def .= '# ';
#           }
        $field_def .= "has_field '$rel' => ( type => '+${target_class}Field', );";
        push @fields, $field_def;
    }
