NAME

DBIx::Class::DateTime::Epoch - Automatic inflation/deflation of epoch-based columns to/from DateTime objects

SYNOPSIS

package MySchema::Foo;

use base qw( DBIx::Class );

__PACKAGE__->load_components( qw( DateTime::Epoch TimeStamp Core ) );
__PACKAGE__->add_columns(
    name => {
        data_type => 'varchar',
        size      => 10,
    },
    bar => { # epoch stored as an int
        data_type        => 'bigint',
        inflate_datetime => 1,
    },
    baz => { # epoch stored as a string
        data_type        => 'varchar',
        size             => 50,
        inflate_datetime => 'epoch',
    },
    # working in conjunction with DBIx::Class::TimeStamp
    creation_time => {
        data_type        => 'bigint',
        inflate_datetime => 1,
        set_on_create    => 1,
    },
    modification_time => {
        data_type        => 'bigint',
        inflate_datetime => 1,
        set_on_create    => 1,
        set_on_update    => 1,
    }
);

DESCRIPTION

This module automatically inflates/deflates DateTime objects from/to epoch values for the specified columns. This module is essentially an extension to DBIx::Class::InflateColumn::DateTime so all of the settings, including locale and timezone, are also valid.

A column will be recognized as an epoch time given one of the following scenarios:

• data_type is an int of some sort and inflate_datetime is also set to a true value

• data_type is some other value (e.g. varchar) and inflate_datetime is explicitly set to epoch.

DBIx::Class::TimeStamp can also be used in conjunction with this module to support epoch-based columns that are automatically set on creation of a row and updated subsequent modifications.

METHODS

add_columns( )

Provides backwards compatibility with the older DateTime::Epoch API.

_inflate_to_datetime( )

Overrides column inflation to use Datetime->from_epoch.

_deflate_from_datetime( )

Overrides column deflation to call epoch() on the column value.
