Neo: I have copied this post to the admin forum so we do not start posting answers to questions in public forums, which will take the fun out of playing computer trivia. Iwill check the DB and get back to you, Mike Baran. In the future, the most important thing when anyone suspects an issue with a true /false statement is to record the trivia number. There are currently over 1000 questions and so we need the number to save time checking the DB. As always,, thanks! I will post back here the results of my research into this (done, see post #3 below).

dbix::class::helper::row::storagevalues
DBIx::Class::Helper::Row::StorageValues(3pm) User Contributed Perl Documentation DBIx::Class::Helper::Row::StorageValues(3pm)
NAME
DBIx::Class::Helper::Row::StorageValues - Keep track of stored vs in-memory row values
VERSION
version 2.013002
SYNOPSIS
package MyApp::Schema::Result::BlogPost;
use parent 'DBIx::Class::Core';
__PACKAGE__->load_components(qw(Helper::Row::StorageValues));
__PACKAGE__->table('BlogPost');
__PACKAGE__->add_columns(
id => {
data_type => 'integer',
is_auto_increment => 1,
},
title => {
data_type => 'varchar',
length => 32,
keep_storage_value => 1,
},
body => {
data_type => 'text',
},
);
1;
# elsewhere:
my $post = $blog_rs->create({
title => 'Components for fun and profit',
body => '...',
});
$post->title('Components for fun');
warn sprintf 'Changing title from %s to %s',
$post->storage_value('title'), $post->title;
$post->update;
DESCRIPTION
This component keeps track of the value for a given column in the database. If you change the column's value and do not call "update", the
"storage_value" will be different; once "update" is called the "storage_value" will be set to the value of the accessor. Note that the
fact that it uses the accessor is an important distinction. If you are using DBIx::Class::FilterColumn or DBIx::Class::InflateColumn it
will get the non-storage or inflated values, respectively.
METHODS
_has_storage_value
$self->_has_storage_value('colname')
returns true if we should store the storage value from the database. Override this if you'd like to enable storage on all integers or
something like that:
sub _has_storage_value {
my ( $self, $column ) = @_;
my $info = $self->column_info($column);
return defined $info->{data_type} && $info->{data_type} eq 'integer';
}
storage_value_columns
$self->storage_value_columns
returns a list of columns to store
get_storage_value
$self->get_storage_value('colname')
returns the value for that column which is in storage
