=head1 NAME

FS::tax_rate_location - Object methods for tax_rate_location records

=head1 SYNOPSIS

  use FS::tax_rate_location;

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

  $error = $record->insert;

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

  $error = $record->delete;

  $error = $record->check;

=head1 DESCRIPTION

An FS::tax_rate_location object represents an example.  FS::tax_rate_location inherits from
FS::Record.  The following fields are currently supported:

=over 4

=item taxratelocationnum

Primary key (assigned automatically for new tax_rate_locations)

=item data_vendor

The tax data vendor

=item geocode

A unique geographic location code provided by the data vendor

=item city

City

=item county

County

=item state

State

=item disabled

If 'Y' this record is no longer active.

=head1 METHODS

=over 4

=item new HASHREF

Creates a new tax rate location.  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 { 'tax_rate_location'; }

=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 tax rate locations.  Set disable to 'Y' instead.";
  # check that it is unused in any cust_bill_pkg_tax_location records instead?
}

=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 tax rate location.  If there is
an error, returns the error, otherwise returns false.  Called by the insert
and replace methods.
