NAME

DBIx::Class::DateTime::Epoch - Automatic inflation/deflation of epoch-based DateTime objects for DBIx::Class

SYNOPSIS

package foo;

use base qw( DBIx::Class );

__PACKAGE__->load_components( qw( DateTime::Epoch Core ) );
__PACKAGE__->add_columns(
    name => {
        data_type => 'varchar',
        size      => 10
    },
    bar => {
        data_type => 'bigint',
        epoch     => 1
    },
    creation_time => {
        data_type => 'bigint',
        epoch     => 'ctime'
    },
    modification_time => {
        data_type => 'bigint',
        epoch     => 'mtime'
    }
);

DESCRIPTION

This module automatically inflates/deflates DateTime objects corresponding to applicable columns. Columns may also be defined to specify their nature, such as columns representing a creation time (set at time of insertion) or a modification time (set at time of every update).

METHODS

register_column

This method will automatically add inflation and deflation rules to a column if an epoch value has been set in the column's definition. If the epoch value is 'ctime' (creation time) or 'mtime' (modification time), it will be registered as such for later use by the insert and the update methods.

insert

This method will set the value of all registered creation time columns to the current time. No changes will be made to a column whose value has already been set.

update

This method will set the value of all registered modification time columns to the current time. This will overwrite a column's value, even if it has been already set.
