9 DBIx::Class::InflateColumn::DateTime - Auto-create DateTime objects from date and datetime columns.
13 Load this component and then declare one or more
14 columns to be of the datetime, timestamp or date datatype.
17 __PACKAGE__->load_components(qw/InflateColumn::DateTime Core/);
18 __PACKAGE__->add_columns(
19 starts_when => { data_type => 'datetime' }
22 Then you can treat the specified column as a L<DateTime> object.
24 print "This event starts the month of ".
25 $event->starts_when->month_name();
27 If you want to set a specific timezone for that field, use:
29 __PACKAGE__->add_columns(
30 starts_when => { data_type => 'datetime', extra => { timezone => "America/Chicago" } }
35 This module figures out the type of DateTime::Format::* class to
36 inflate/deflate with based on the type of DBIx::Class::Storage::DBI::*
37 that you are using. If you switch from one database to a different
38 one your code should continue to work without modification (though note
39 that this feature is new as of 0.07, so it may not be perfect yet - bug
40 reports to the list very much welcome).
42 For more help with using components, see L<DBIx::Class::Manual::Component/USING>.

52 Chains with the L<DBIx::Class::Row/register_column> method, and sets
53 up datetime columns appropriately. This would not normally be
54 directly called by end users.
