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.
