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.
