NAME

DBIx::Class::InflateColumn::ISBN - Auto-create Business::ISBN objects from columns.

VERSION

Version 0.04000

SYNOPSIS

Load this component and declare columns as ISBNs with the appropriate format.

package Library;
__PACKAGE__->load_components(qw/InflateColumn::ISBN Core/);
__PACKAGE__->add_columns(
    isbn => {
        data_type => 'varchar',
        size => 13,
        is_nullable => 0,
        is_isbn => 1,
        as_string => 0,
    }
);

It has to be a varchar rather than a simple integer given that it is possible for ISBNs to contain the character X. Old style ISBNs are 10 characters, not including hyphens, but new style ones are 13 characters.

The as_string attribute is optional, and if set to 1 then values will be stored in the database with hyphens in the appopriate places. In this case, an extra 3 characters will be required.

Then you can treat the specified column as a Business::ISBN object.

print 'ISBN: ', $book->isbn->as_string;
print 'Publisher code: ', $book->isbn->publisher_code;

METHODS

isbn_class

Arguments: $class

Gets/sets the address class that the columns should be inflated into. The default class is Business::ISBN and only that is currently supported.

register_column

Chains with "register_column" in DBIx::Class::Row, and sets up ISBN columns appropriately. This would not normally be called directly by end users.
