DBIx::Class::Ordered - Modify the position of objects in an ordered list.
group excluding the one you called it on.
The ordering is a backwards-compatibility artifact - if you need
-a resultset with no ordering applied use L</_siblings>
+a resultset with no ordering applied use C<_siblings>

# since the columns are already re-set the _grouping_clause is correct
# move_to_group() knows how to get the original storage values

=head1 METHODS FOR EXTENDING ORDERED
local $rsrc->schema->{_ORDERED_INTERNAL_UPDATE} = 1;
my @pcols = $rsrc->primary_columns;
if (
- first { $_ eq $position_column } ( map { @$_ } (values %{{ $rsrc->unique_constraints }} ) )
+ grep { $_ eq $position_column } ( map { @$_ } (values %{{ $rsrc->unique_constraints }} ) )
) {
my $clean_rs = $rsrc->resultset;
Using a database defined default_value on one of your group columns
could result in the position not being assigned correctly.
