=head1 NAME

FS::cgp_rule - Object methods for cgp_rule records

=head1 SYNOPSIS

  use FS::cgp_rule;

  $record = new FS::cgp_rule \%hash;
  $record = new FS::cgp_rule { 'column' => 'value' };

  $error = $record->insert;

  $error = $new_record->replace($old_record);

  $error = $record->delete;

  $error = $record->check;

=head1 DESCRIPTION

An FS::cgp_rule object represents a mail filtering rule.  FS::cgp_rule
inherits from FS::Record.  The following fields are currently supported:

=over 4

=item rulenum

primary key

=item name

name

=item comment

comment

=item svcnum

svcnum

=item priority

priority

=head1 METHODS

=over 4

=item new HASHREF

Creates a new rule.  To add the rule 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

# the new method can be inherited from FS::Record, if a table method is defined

sub table { 'cgp_rule'; }

=item insert

Adds this record to the database.  If there is an error, returns the error,
otherwise returns false.

=cut

# the insert method can be inherited from FS::Record

=item delete

Delete this record from the database.

=cut

sub delete {
  my $self = shift;

  local $SIG{HUP} = 'IGNORE';
  local $SIG{INT} = 'IGNORE';
  local $SIG{QUIT} = 'IGNORE';
  local $SIG{TERM} = 'IGNORE';
  local $SIG{TSTP} = 'IGNORE';
  local $SIG{PIPE} = 'IGNORE';

  my $oldAutoCommit = $FS::UID::AutoCommit;
  local $FS::UID::AutoCommit = 0;
  my $dbh = dbh;

  my @del = $self->cgp_rule_condition;
  push @del, $self->cgp_rule_action;

  foreach my $del (@del) {
    my $error = $del->delete;
    if ( $error ) {
      $dbh->rollback if $oldAutoCommit;
      return $error;
    }
  }

  my $error = $self->SUPER::delete(@_);
  if ( $error ) {
    $dbh->rollback if $oldAutoCommit;
    return $error;
  }

  $dbh->commit or die $dbh->errstr if $oldAutoCommit;

}

=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

# the replace method can be inherited from FS::Record

=item check

Checks all fields to make sure this is a valid rule.  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('rulenum')
    || $self->ut_text('name')
    || $self->ut_textn('comment')
    || $self->ut_foreign_key('svcnum', 'cust_svc', 'svcnum')
    || $self->ut_number('priority')
  ;
  return $error if $error;

  $self->SUPER::check;
}

=item cust_svc

=cut

sub cust_svc {
  my $self = shift;
  qsearchs('cust_svc', { 'svcnum' => $self->svcnum } );
}

=item cgp_rule_condition

Returns the conditions associated with this rule, as FS::cgp_rule_condition
objects.

=cut

sub cgp_rule_condition {
  my $self = shift;
  qsearch('cgp_rule_condition', { 'rulenum' => $self->rulenum } );
}

=item cgp_rule_action

Returns the actions associated with this rule, as FS::cgp_rule_action
objects.

=cut

sub cgp_rule_action {
  my $self = shift;
  qsearch('cgp_rule_action', { 'rulenum' => $self->rulenum } );
}
