=head1 NAME
FS::cust_refund - Object method for cust_refund objects
=head1 SYNOPSIS
use FS::cust_refund;
$record = create FS::cust_refund \%hash;
$record = create FS::cust_refund { 'column' => 'value' };
$error = $record->insert;
$error = $new_record->replace($old_record);
$error = $record->delete;
$error = $record->check;
=head1 DESCRIPTION
An FS::cust_refund represents a refund. FS::cust_refund inherits from
FS::Record. The following fields are currently supported:
=over 4
=item refundnum - primary key (assigned automatically for new refunds)
=item crednum - Credit (see L<FS::cust_credit>)
=item refund - Amount of the refund
=item _date - specified as a UNIX timestamp; see L<perlfunc/"time">. Also see
L<Time::Local> and L<Date::Parse> for conversion functions.
=item payby - `CARD' (credit cards), `BILL' (billing), or `COMP' (free)
=item payinfo - card number, P.O.#, or comp issuer (4-8 lowercase alphanumerics; think username)
=item otaker - order taker (assigned automatically, see L<FS::UID>)
=back
=head1 METHODS
=over 4
=item create HASHREF
Creates a new refund. To add the refund to the database, see L<"insert">.
=cut
sub create {
my($proto,$hashref)=@_;
#now in FS::Record::new
#my($field);
#foreach $field (fields('cust_refund')) {
# $hashref->{$field}='' unless defined $hashref->{$field};
#}
$proto->new('cust_refund',$hashref);
}
=item insert
Adds this refund to the database, and updates the credit (see
L<FS::cust_credit>).
=cut
sub insert {
my($self)=@_;
my($error);
$error=$self->check;
return $error if $error;
my($old_cust_credit) = qsearchs('cust_credit', {
'crednum' => $self->getfield('crednum')
} );
return "Unknown crednum" unless $old_cust_credit;
my(%hash)=$old_cust_credit->hash;
$hash{credited} = sprintf("%.2f",$hash{credited} - $self->getfield('refund') );
my($new_cust_credit) = create FS::cust_credit ( \%hash );
local $SIG{HUP} = 'IGNORE';
local $SIG{INT} = 'IGNORE';
local $SIG{QUIT} = 'IGNORE';
local $SIG{TERM} = 'IGNORE';
local $SIG{TSTP} = 'IGNORE';
$error=$new_cust_credit -> replace($old_cust_credit);
return "Error modifying cust_credit: $error" if $error;
$self->add;
}
=item delete
Currently unimplemented (accounting reasons).
=cut
sub delete {
return "Can't (yet?) delete cust_refund records!";
#template code below
# my($self)=@_;
#
# $self->del;
}
=item replace OLD_RECORD
Currently unimplemented (accounting reasons).
=cut
sub replace {
return "Can't (yet?) modify cust_refund records!";
#template code below
# my($new,$old)=@_;
# return "(Old) Not a cust_refund record!" unless $old->table eq "cust_refund";
#
# $new->check or
# $new->rep($old);
}
=item check
Checks all fields to make sure this is a valid refund. If there is an error,
returns the error, otherwise returns false. Called by the insert method.
=cut
sub check {
my($self)=@_;
return "Not a cust_refund record!" unless $self->table eq "cust_refund";
