Why am I getting use of unininitialized value in sprintf from the DBIx::Class::InflateColumn::DateTime object?

This seems to have most started since I upgrade my DBIx::Class and I can't figure out what I'm doing wrong.

Use of uninitialized value in sprintf at /opt/perl-5.10.1/lib/site_perl/5.10.1/DBIx/Class/InflateColumn/DateTime.pm line 192.
 at /opt/perl-5.10.1/lib/site_perl/5.10.1/DBIx/Class/InflateColumn/DateTime.pm line 192
    DBIx::Class::InflateColumn::DateTime::_flate_or_fallback('OpusVL::AppKitX::TelecomsBilling::Schema::Result::AsteriskCdr...', '2009-11-13 09:00:00', 'HASH(0x2a85488)', 'parse_%s') called at /opt/perl-5.10.1/lib/site_perl/5.10.1/DBIx/Class/InflateColumn/DateTime.pm line 199

My column definition in the result file is,

package Module1::Schema::Result::AsteriskCdrRecord;

# Created by DBIx::Class::Schema::Loader
# DO NOT MODIFY THE FIRST PART OF THIS FILE

use strict;
use warnings;

use Moose;
use MooseX::NonMoose;
use namespace::autoclean;
extends 'DBIx::Class::Core';

    "call_start",
    {
        inflate_datetime    => 1 ,
        data_type           => "timestamp without time zone",
        default_value       => undef,
        is_nullable         => 0,
        size                => 8,

    "call_end",
    {
        inflate_datetime    => 1,

        default_value       => undef,

    "created",
    { data_type => 'datetime', set_on_create => 1 },
    "updated",
    { data_type => 'datetime', set_on_create => 1, set_on_update => 1 },
);

The messing about doing things again after the break is to prevent the Schema::Loader from having problems with me modifying code it's generated.

What do I need to do to prevent the warnings about the uninitialized value? This is using version 0.开发者_运维百科08124 of DBIx::Class (although I think it occurred with the version before too but I didn't get around to investigation this problem then).


A couple of things to improve the code above:

  • Remove the extra "Core" from the second load_components call, you already have it in the "extends" line.

  • The second "add_columns" call can be made shorter by using the new "+col" syntax which allows you to amend/update an existing column definition, rather than adding a whole new one, see ResultSource docs.
