  $error = $record->insert;

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

  $error = $record->delete;

  $error = $record->check;

=head1 METHODS

=over 4

=item new HASHREF

Creates a new record.  To add the record 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 { 'cust_bill_pkg_tax_rate_location'; }

=item insert

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

=item delete

Delete this record from the database.

=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.

=item check

Checks all fields to make sure this is a valid record.  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('billpkgtaxratelocationnum')
    || $self->ut_foreign_key('billpkgnum', 'cust_bill_pkg', 'billpkgnum' )
    || $self->ut_number('taxnum') #cust_bill_pkg/tax_rate key, based on taxtype
    || $self->ut_enum('taxtype', [ qw( FS::cust_main_county FS::tax_rate ) ] )
    || $self->ut_textn('locationtaxid')
    || $self->ut_foreign_key('taxratelocationnum', 'tax_rate_location', 'taxratelocationnum' )
    || $self->ut_money('amount')
  ;
  return $error if $error;

  $self->SUPER::check;
}

=item cust_bill_pkg

Returns the associated cust_bill_pkg object

=item tax_rate_location

Returns the associated tax_rate_location object

=item taxname

Returns the tax name (the itemdesc).

=cut

sub taxname {
  my $self = shift;
  my $tax_rate = FS::tax_rate->by_key($self->taxnum)
    or return '';

}

=item desc

Returns a description for this tax line item constituent.  Currently this
is the desc of the associated line item followed by the
state,county,city,locationtaxid for the location in parentheses.

=cut

sub desc {
  my $self = shift;
  my $tax_rate_location = $self->tax_rate_location;
  my $location = join(', ', grep { $_ }
                            map { $tax_rate_location->$_ }
                            qw( state county city )
  );
  $location .= ( $location && $self->locationtaxid ) ? ', ' : '';
  $location .= $self->locationtaxid;
  my $cust_bill_pkg_desc = $self->billpkgnum
                         ? $self->cust_bill_pkg->desc
                         : $self->cust_bill_pkg_desc;

  $balance -= $_->amount foreach ( $self->cust_credit_bill_pkg('setup') );
  $balance = sprintf( '%.2f', $balance );
  $balance =~ s/^\-0\.00$/0.00/; #yay ieee fp
