| 14 | =head1 NAME | ||||
| 15 | |||||
| 16 | DBIx::Class::TimeStamp - DBIx::Class extension to update and create date and time based fields | ||||
| 17 | |||||
| 18 | =head1 DESCRIPTION | ||||
| 19 | |||||
| 20 | Works in conjunction with InflateColumn::DateTime to automatically set update | ||||
| 21 | and create date and time based fields in a table. | ||||
| 22 | |||||
| 23 | =head1 SYNOPSIS | ||||
| 24 | |||||
| 25 | package My::Schema; | ||||
| 26 | |||||
| 27 | __PACKAGE__->load_components(qw( TimeStamp ... Core )); | ||||
| 28 | |||||
| 29 | __PACKAGE__->add_columns( | ||||
| 30 | id => { data_type => 'integer' }, | ||||
| 31 | t_created => { data_type => 'datetime', set_on_create => 1 }, | ||||
| 32 | t_updated => { data_type => 'datetime', | ||||
| 33 | set_on_create => 1, set_on_update => 1 }, | ||||
| 34 | ); | ||||
| 35 | |||||
| 36 | Now, any update or create actions will update the specified columns with the | ||||
| 37 | current time, using the DateTime inflator. | ||||
| 38 | |||||
| 39 | This is effectively trigger emulation to get consistent behavior across | ||||
| 40 | databases that either implement them poorly or not at all. | ||||

| 71 | =head1 METHODS | ||||
| 72 | |||||
| 73 | =head2 get_timestamp | ||||
| 74 | |||||
| 75 | Returns a DateTime object pointing to now. Override this method if you have | ||||
| 76 | different time accounting functions, or want to do anything special. | ||||
| 77 | |||||
| 78 | The date and time objects in the database are expected to be inflated. As such | ||||
| 79 | you can be pretty flexible with what you want to return here. | ||||
