=head1 NAME

FS::part_export - Object methods for part_export records

=head1 SYNOPSIS

  use FS::part_export;

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

  #($new_record, $options) = $template_recored->clone( $svcpart );

  $error = $record->insert( { 'option' => 'value' } );
  $error = $record->insert( \%options );

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

  $error = $record->delete;

  $error = $record->check;

=head1 DESCRIPTION

An FS::part_export object represents an export of Freeside data to an external
provisioning system.  FS::part_export inherits from FS::Record.  The following
fields are currently supported:

=over 4

=item exportnum - primary key

=item machine - Machine name 

=item exporttype - Export type

=item nodomain - blank or "Y" : usernames are exported to this service with no domain

=back

=head1 METHODS

=over 4

=item new HASHREF

Creates a new export.  To add the export 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 { 'part_export'; }

=cut

#=item clone SVCPART
#
#An alternate constructor.  Creates a new export by duplicating an existing
#export.  The given svcpart is assigned to the new export.
#
#Returns a list consisting of the new export object and a hashref of options.
#
#=cut
#
#sub clone {
#  my $self = shift;
#  my $class = ref($self);
#  my %hash = $self->hash;
#  $hash{'exportnum'} = '';
#  $hash{'svcpart'} = shift;
#  ( $class->new( \%hash ),
#    { map { $_->optionname => $_->optionvalue }
#        qsearch('part_export_option', { 'exportnum' => $self->exportnum } )
#    }
#  );
#}

=item insert HASHREF

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

If a hash reference of options is supplied, part_export_option records are
created (see L<FS::part_export_option>).

=item replace OLD_RECORD HASHREF

Replaces the OLD_RECORD with this one in the database.  If there is an error,
returns the error, otherwise returns false.

If a hash reference of options is supplied, part_export_option records are
created or modified (see L<FS::part_export_option>).

an error, returns the error, otherwise returns false.  Called by the insert
