=head1 NAME
FS::part_pkg_report_option - Object methods for part_pkg_report_option records
=head1 SYNOPSIS
use FS::part_pkg_report_option;
$record = new FS::part_pkg_report_option \%hash;
$record = new FS::part_pkg_report_option { 'column' => 'value' };
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::part_pkg_report_option object represents a package definition optional
reporting classification. FS::part_pkg_report_option inherits from
FS::Record. The following fields are currently supported:
=over 4
=item num
primary key
=item name
name - The name associated with the reporting option
=item disabled
disabled - set to 'Y' to prevent addition to new packages
=back
=head1 METHODS
=over 4
=item new HASHREF
Creates a new report option. To add the option to the database, see L<"insert">.
Note that this stores the hash reference, not a distinct copy of the hash it
points to. You can ask the object for a copy with the I<hash> method.
=cut
sub table { 'part_pkg_report_option'; }
=item insert
Adds this record to the database. If there is an error, returns the error,
otherwise returns false.
=cut
=item delete
Delete this record from the database.
=cut
sub delete {
return "Can't delete part_pkg_report_option records!";
}
=item replace OLD_RECORD
Replaces the OLD_RECORD with this one in the database. If there is an error,
returns the error, otherwise returns false.
=cut
=item check
Checks all fields to make sure this is a valid example. If there is
an error, returns the error, otherwise returns false. Called by the insert
and replace methods.
=cut
# the check method should currently be supplied - FS::Record contains some
# data checking routines
sub check {
my $self = shift;
my $error =
$self->ut_numbern('num')
|| $self->ut_text('name')
|| $self->ut_enum('disabled', [ '', 'Y' ])
;
return $error if $error;
$self->SUPER::check;
}
=back
=head1 CLASS METHODS
=over 4
=item subsets OPTIONNUM, ...
Given a list of report_option numbers, determines all combinations of those
numbers that exist on actual package definitions. For each such combination,
returns an arrayref of report_option numbers, followed by an arrayref of
corresponding report class names. This is used for a search optimization.
=cut
# probably doesn't belong here, but there's not a better place for it
# and optimizations are, by nature, hackish
sub subsets {
my ($self, @nums) = @_;
my @optionnames = map { "'report_option_$_'" } @nums;
my $where = "WHERE optionname IN(".join(',',@optionnames).")"
if @nums;
my $subselect =
"SELECT pkgpart, replace(optionname, 'report_option_', '')::int AS num ".
"FROM part_pkg_option $where ".
"ORDER BY pkgpart, num";
my $select =
"SELECT DISTINCT array_to_string(array_agg(num), ','), ".
"array_to_string(array_agg(name), ',') ".
"FROM ($subselect) AS x JOIN part_pkg_report_option USING (num) ".
"GROUP BY pkgpart";
my $dbh = dbh;
my $sth = $dbh->prepare($select)
or die $dbh->errstr; # seriously, this should never happen
$sth->execute
or die $sth->errstr;
# return a pair of entries for the null set (conventionally we use zero
# for that)
( [ 0 ], [ '(empty class)' ],
# followed by the first two columns: report class numbers and names
map { [ split(',',$_->[0]) ],
[ split(',',$_->[1]) ] } @{ $sth->fetchall_arrayref }
);
}
=back
=head1 BUGS
Overlaps somewhat with pkg_class and pkg_category
