+=head1 NAME
+
+FS::cust_credit - Object methods for cust_credit records
+
+=head1 SYNOPSIS
+
+ use FS::cust_credit;
+
+ $record = create FS::cust_credit \%hash;
+ $record = create FS::cust_credit { 'column' => 'value' };
+
+ $error = $record->insert;
+
+ $error = $new_record->replace($old_record);
+
+ $error = $record->delete;
+
+ $error = $record->check;
+
+=head1 DESCRIPTION
+
+An FS::cust_credit object represents a credit. FS::cust_credit inherits from
+FS::Record. The following fields are currently supported:
+
+=over 4
+
+=item crednum - primary key (assigned automatically for new credits)
+
+=item custnum - customer (see L<FS::cust_main>)
+
+=item amount - amount of the credit
+
+=item credited - how much of this credit that is still outstanding, which is
+amount minus all refunds (see L<FS::cust_refund>).
+
+=item _date - specified as a UNIX timestamp; see L<perlfunc/"time">. Also see
+L<Time::Local> and L<Date::Parse> for conversion functions.
+
+=item otaker - order taker (assigned automatically, see L<FS::UID>)
+
+=item reason - text
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item create HASHREF
+
+Creates a new credit. To add the credit to the database, see L<"insert">.
+
+=cut
+
+sub create {
+ my($proto,$hashref)=@_;
+
+ #now in FS::Record::new
+ #my($field);
+ #foreach $field (fields('cust_credit')) {
+ # $hashref->{$field}='' unless defined $hashref->{$field};
+ #}
+
+ $proto->new('cust_credit',$hashref);
+}
+
+=item insert
+
+Adds this credit to the database ("Posts" the credit). If there is an error,
+returns the error, otherwise returns false.
+
+When adding new invoices, credited must be amount (or null, in which case it is
+automatically set to amount).
+
+=cut
+
+sub insert {
+ my($self)=@_;
+
+ $self->setfield('credited',$self->amount) if $self->credited eq '';
+ return "credited != amount!"
+ unless $self->credited == $self->amount;
+
+ $self->check or
+ $self->add;
+}
+
+=item delete
+
+Currently unimplemented.
+
+=cut
+
+sub delete {
+ return "Can't remove credit!"
+ #my($self)=@_;
+ #$self->del;
+}
+
+=item replace OLD_RECORD
+
+Replaces the OLD_RECORD with this one in the database. If there is an error,
+returns the error, otherwise returns false.
+
+Only credited may be changed. Credited is normally updated by creating and
+inserting a refund (see L<FS::cust_refund>).
+
+=cut
+
+sub replace {
+ my($new,$old)=@_;
+ return "(Old) Not a cust_credit record!" unless $old->table eq "cust_credit";
+ return "Can't change crednum!"
+ unless $old->getfield('crednum') eq $new->getfield('crednum');
+ return "Can't change custnum!"
+ unless $old->getfield('custnum') eq $new->getfield('custnum');
+ return "Can't change date!"
+ unless $old->getfield('_date') eq $new->getfield('_date');
+ return "Can't change amount!"
+ unless $old->getfield('amount') eq $new->getfield('amount');
+ return "(New) credited can't be > (new) amount!"
+ if $new->getfield('credited') > $new->getfield('amount');
+
+ $new->check or
+ $new->rep($old);
+}
+
+=item check
+
+Checks all fields to make sure this is a valid credit. If there is an error,
+returns the error, otherwise returns false. Called by the insert and replace
+methods.

+ my($self)=@_;

+
+The delete method.
