DBIx::Class::DateTime::Epoch

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,
}
);

DATETIME::FORMAT DEPENDENCY

There have been no assumptions made as to what RDBMS you will be using. As per the note in the DBIx::Class::InflateColumn::DateTime documentation, you will need to install the DateTime::Format::* module that matches your RDBMS of choice.

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.
