=head1 NAME
FS::part_pkg::prorate_Mixin - Mixin class for part_pkg:: classes that
need to prorate partial months
=head1 SYNOPSIS
package FS::part_pkg::...;
use base qw( FS::part_pkg::prorate_Mixin );
sub calc_recur {
...
if( conditions that trigger prorate ) {
# sets $$sdate and $param->{'months'}, returns the prorated charge
$charges = $self->calc_prorate($cust_pkg, $sdate, $param, $cutoff_day);
}
...
}
=head METHODS
=item calc_prorate CUST_PKG
Takes all the arguments of calc_recur, followed by a day of the month
to prorate to. Calculates a prorated charge from the $sdate to that day,
and sets the $sdate and $param->{months} accordingly.
Options:
- recur_fee: The charge to use for a complete billing period.
- add_full_period: Bill for the time up to the prorate day plus one full
billing period after that.
- prorate_round_day: Round the current time to the nearest full day,
instead of using the exact time.
