10 DBIx::Class::PK::Auto - Automatic Primary Key class
16 This class overrides the insert method to get automatically
17 incremented primary keys.
19 You don't want to be using this directly - instead load the appropriate
20 one for your database, e.g. PK::Auto::SQLite
26 Overrides insert so that it will get the value of autoincremented
32 my ($self, @rest) = @_;
33 my $ret = $self->next::method(@rest);
35 # if all primaries are already populated, skip auto-inc
37 map { $populated++ if defined $self->get_column($_) } $self->primary_columns;
38 return $ret if ( $populated == scalar $self->primary_columns );
40 my ($pri, $too_many) =
41 (grep { $self->column_info($_)->{'auto_increment'} }
42 $self->primary_columns)
43 || $self->primary_columns;
44 $self->throw( "More than one possible key found for auto-inc on ".ref $self )
46 unless (defined $self->get_column($pri)) {
47 $self->throw( "Can't auto-inc for $pri on ".ref $self.": no _last_insert_id method" )
48 unless $self->can('last_insert_id');
49 my $id = $self->last_insert_id;
50 $self->throw( "Can't get last insert id" ) unless $id;
51 $self->store_column($pri => $id);
58 Manually define the correct sequence for your table, to avoid the overhead
59 associated with looking up the sequence automatically.
