VERSION

       version 2.019002

SYNOPSIS

        package MyApp::Schema::Result::KittenRobot;

        use base 'DBIx::Class::Core';

        __PACKAGE__->load_components(qw{Helper::Row::ToJSON});

        __PACKAGE__->table('KittenRobot');
        __PACKAGE__->add_columns(
           id => {
              data_type         => 'integer',
              is_auto_increment => 1,
           },
           kitten => {
              data_type         => 'integer',
           },
           robot => {
              data_type         => 'text',
              is_nullable       => 1,
           },
           your_mom => {
              data_type         => 'blob',
              is_nullable       => 1,
              is_serializable   => 1,
           },
        );

        1;

       This helper adds a JSON method like the following:

        sub TO_JSON {
           return {
              id       => $self->id,
              kitten   => $self->kitten,
              # robot  => $self->robot,    # <-- doesn't serialize text columns
              your_mom => $self->your_mom, # <-- normally wouldn't but explicitly
                                           #     asked for in the column spec above
           }
        }

METHODS

   _is_column_serializable
        $self->_is_column_serializable('kitten')

       returns true if a column should be serializable or not.  Currently this marks everything
       as serializable unless "is_serializable" is set to false, or "data_type" is a "blob",
       "text", or "ntext" columns.  If you wanted to only have explicit serialization you might
       override this method to look like this:

        sub _is_column_serializable {
           my ( $self, $column ) = @_;

           my $info = $self->column_info($column);

           return defined $info->{is_serializable} && $info->{is_serializable};
        }

   serializable_columns
        $self->serializable_columns

       simply returns a list of columns that TO_JSON should serialize.

   TO_JSON
        $self->TO_JSON

       returns a hashref representing your object.  Override this method to add data to the
       returned hashref:

        sub TO_JSON {
           my $self = shift;

           return {
              customer_name => $self->customer->name,
              %{ $self->next::method },
           }
        }
