package FS::cust_credit_refund;
use base qw( FS::cust_main_Mixin FS::Record );
use strict;
=head1 NAME
FS::cust_credit_refund - Object methods for cust_bill_pay records
=head1 SYNOPSIS
use FS::cust_credit_refund;
$record = new FS::cust_credit_refund \%hash;
$record = new FS::cust_credit_refund { 'column' => 'value' };
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::cust_credit_refund represents the application of a refund to a specific
credit. FS::cust_credit_refund inherits from FS::Record. The following fields
are currently supported:
=over 4
=item creditrefundnum - primary key (assigned automatically)
=item crednum - Credit (see L<FS::cust_credit>)
=item refundnum - Refund (see L<FS::cust_refund>)
=item amount - Amount of the refund to apply to the specific credit.
=item _date - specified as a UNIX timestamp; see L<perlfunc/"time">. Also see
L<Time::Local> and L<Date::Parse> for conversion functions.
=back
=head1 METHODS
=over 4
=item new HASHREF
Creates a new record. To add the record to the database, see L<"insert">.
=cut
sub table { 'cust_credit_refund'; }
=item insert
Adds this record to the database. If there is an error, returns the error,
otherwise returns false.
=cut
sub insert {
my $self = shift;
return "Can't apply refund to closed credit"
if $self->cust_credit->closed =~ /^Y/i;
return "Can't apply credit to closed refund"
if $self->cust_refund->closed =~ /^Y/i;
$self->SUPER::insert(@_);
}
=item delete
Remove this cust_credit_refund from the database. If there is an error,
returns the error, otherwise returns false.
=cut
sub delete {
my $self = shift;
return "Can't remove refund from closed credit"
if $self->cust_credit->closed =~ /^Y/i;
return "Can't remove credit from closed refund"
if $self->cust_refund->closed =~ /^Y/i;
$self->SUPER::delete(@_);
}
=item replace OLD_RECORD
Currently unimplemented (accounting reasons).
=cut
sub replace {
return "Can't (yet?) modify cust_credit_refund records!";
}
=item check
Checks all fields to make sure this is a valid refund application. If there is
an error, returns the error, otherwise returns false. Called by the insert
method.
=cut
sub check {
my $self = shift;
my $error =
$self->ut_numbern('creditrefundnum')
|| $self->ut_number('crednum')
|| $self->ut_number('refundnum')
|| $self->ut_money('amount')
|| $self->ut_numbern('_date')
;
return $error if $error;
return "amount must be > 0" if $self->amount <= 0;
return "unknown cust_credit.crednum: ". $self->crednum
unless my $cust_credit = $self->cust_credit;
return "Unknown refund"
unless my $cust_refund = $self->cust_refund;
$self->_date(time) unless $self->_date;
return "Cannot apply more than remaining value of credit"
unless $self->amount <= $cust_credit->credited;
return "Cannot apply more than remaining value of refund"
unless $self->amount <= $cust_refund->unapplied;
$self->SUPER::check;
}
=item cust_refund
Returns the refund (see L<FS::cust_refund>)
=item cust_credit
Returns the credit (see L<FS::cust_credit>)
=back
=head1 BUGS
Delete and replace methods.
the checks for over-applied refunds could be better done like the ones in
cust_bill_credit

base documentation.
