NAME

HTML::FormHandler::TraitFor::DBICFields - role to get fields from DBIx::Class result source

VERSION

version 0.17

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;
      }
  }
