=head1 NAME
FS::domain_record - Object methods for domain_record records
=head1 SYNOPSIS
use FS::domain_record;
$record = new FS::domain_record \%hash;
$record = new FS::domain_record { 'column' => 'value' };
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::domain_record object represents an entry in a DNS zone.
FS::domain_record inherits from FS::Record. The following fields are currently
supported:
=over 4
=item recnum - primary key
=item svcnum - Domain (see L<FS::svc_domain>) of this entry
=item reczone - partial (or full) zone for this entry
=item recaf - address family for this entry, currently only `IN' is recognized.
=item rectype - record type for this entry (A, MX, etc.)
=item recdata - data for this entry
=back
=head1 METHODS
=over 4
=item new HASHREF
Creates a new entry. To add the example 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 { 'domain_record'; }
=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
=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('recnum')
|| $self->ut_number('svcnum')
;
return $error if $error;
return "Unknown svcnum (in svc_domain)"
unless qsearchs('svc_domain', { 'svcnum' => $self->svcnum } );
$self->reczone =~ /^(@|[a-z0-9\.\-]+)$/
or return "Illegal reczone: ". $self->reczone;
$self->reczone($1);
$self->recaf =~ /^(IN)$/ or return "Illegal recaf: ". $self->recaf;
$self->recaf($1);
$self->rectype =~ /^(SOA|NS|MX|A|PTR|CNAME)$/
or return "Illegal rectype (only SOA NS MX A PTR CNAME recognized): ".
$self->rectype;
$self->rectype($1);
if ( $self->rectype eq 'SOA' ) {
my $recdata = $self->recdata;
$recdata =~ s/\s+/ /g;
$recdata =~ /^([a-z0-9\.\-]+ [\w\-\+]+\.[a-z0-9\.\-]+ \( (\d+ ){5}\))$/
or return "Illegal data for SOA reocrd: $recdata";
$self->recdata($1);
} elsif ( $self->rectype eq 'NS' ) {
$self->recdata =~ /^([a-z0-9\.\-]+)$/
or return "Illegal data for NS record: ". $self->recdata;
$self->recdata($1);
} elsif ( $self->rectype eq 'MX' ) {
$self->recdata =~ /^(\d+)\s+([a-z0-9\.\-]+)$/
or return "Illegal data for MX record: ". $self->recdata;
$self->recdata("$1 $2");
} elsif ( $self->rectype eq 'A' ) {
$self->recdata =~ /^((\d{1,3}\.){3}\d{1,3})$/
or return "Illegal data for A record: ". $self->recdata;
$self->recdata($1);
} elsif ( $self->rectype eq 'PTR' ) {
$self->recdata =~ /^([a-z0-9\.\-]+)$/
or return "Illegal data for PTR record: ". $self->recdata;
$self->recdata($1);
} elsif ( $self->rectype eq 'CNAME' ) {
$self->recdata =~ /^([a-z0-9\.\-]+)$/
or return "Illegal data for CNAME record: ". $self->recdata;

=head1 BUGS
The data validation doesn't check everything it could. In particular,
there is no protection against bad data that passes the regex, duplicate
SOA records, forgetting the trailing `.', impossible IP addersses, etc. Of
course, it's still better than editing the zone files directly. :)
