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) =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). =item _date - specified as a UNIX timestamp; see L. Also see L and L for conversion functions. =item otaker - order taker (assigned automatically, see L) =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)=@_; #$self->del; } =item replace OLD_RECORD Replaces the OLD_RECORD with this one in the database. If there is an error, returns the error, otherwise returns false. Only credited may be changed. Credited is normally updated by creating and inserting a refund (see L). =cut sub replace { my($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. =cut sub check { my($self)=@_; return "Not a cust_credit record!" unless $self->table eq "cust_credit"; my($recref) = $self->hashref; $recref->{crednum} =~ /^(\d*)$/ or return "Illegal crednum"; $recref->{crednum} = $1; $recref->{custnum} =~ /^(\d+)$/ or return "Illegal custnum"; $recref->{custnum} = $1; return "Unknown customer" unless qsearchs('cust_main',{'custnum'=>$recref->{custnum}}); $recref->{_date} =~ /^(\d*)$/ or return "Illegal date"; $recref->{_date} = $recref->{_date} ? $1 : time; $recref->{amount} =~ /^(\d+(\.\d\d)?)$/ or return "Illegal amount"; $recref->{amount} = $1; $recref->{credited} =~ /^(\-?\d+(\.\d\d)?)$/ or return "Illegal credited"; $recref->{credited} = $1; #$recref->{otaker} =~ /^(\w+)$/ or return "Illegal otaker"; #$recref->{otaker} = $1; $self->otaker(getotaker); $self->ut_textn('reason'); } =back =head1 BUGS The delete method.
