NAME

       DBIx::Class::TimeStamp - DBIx::Class extension to update and create date and time based fields

DESCRIPTION

       Works in conjunction with InflateColumn::DateTime to automatically set update and create date and time based fields in a table.

SYNOPSIS

	package My::Schema;

	__PACKAGE__->load_components(qw( TimeStamp ... Core ));

	__PACKAGE__->add_columns(
	   id => { data_type => 'integer' },
	   t_created => { data_type => 'datetime', set_on_create => 1 },
	   t_updated => { data_type => 'datetime',
	       set_on_create => 1, set_on_update => 1 },
	);

       Now, any update or create actions will update the specified columns with the current time, using the DateTime inflator.

       This is effectively trigger emulation to get consistent behavior across databases that either implement them poorly or not at all.

METHODS

   get_timestamp
       Returns a DateTime object pointing to now.  Override this method if you have different time accounting functions, or want to do anything
       special.

       The date and time objects in the database are expected to be inflated.  As such you can be pretty flexible with what you want to return
       here.

NAME

       DBIx::Class::KiokuDB - Refer to KiokuDB objects from DBIx::Class tables.

SYNOPSIS

       See DBIx::Class::Schema::KiokuDB.

	   package MyApp::DB::Result::Album;
	   use base qw(DBIx::Class);

	   __PACKAGE__>load_components(qw(Core KiokuDB));

	   __PACKAGE__->table('album');

	   __PACKAGE__->add_columns(
	       id => { data_type => "integer" },
	       title => { data_type => "varchar" },

	       # the foreign key for the KiokuDB object:
	       metadata => { data_type => "varchar" },
	   );

	   __PACKAGE__->set_primary_key('id');

	   # enable a KiokuDB rel on the column:
	   __PACKAGE__->kiokudb_column('metadata');

DESCRIPTION

       This DBIx::Class component provides the code necessary for DBIx::Class::Row objects to refer to KiokuDB objects stored in
       KiokuDB::Backend::DBI.

CLASS METHODS

       kiokudb_column $rel
	   Declares a relationship to any KiokuDB object.

	   In future versions adding relationships to different sub-collections will be possible as well.

METHODS

       store
	   A convenience method that calls "store" in KiokuDB on all referenced KiokuDB objects, and then invokes "insert_or_update" on $self.

       get_kiokudb_column $col
       set_kiokudb_column $col, $obj
       store_kiokudb_column $col, $obj
	   See DBIx::Class::Row.

OVERRIDDEN METHODS

       new Recognizes objects passed in as column values, much like standard relationships do.

       insert
	   Also calls "insert" in KiokuDB on all referenced objects that are not in the KiokuDB storage.

       update
	   Adds a check to ensure that all referenced KiokuDB objects are in storage.
