In rare cases, you’d like to calculate action in your own way, or to modify attributes actions and fks in Filter.pm. You can do these by overriding get_action. Just to make sure you return a two-element array: the action and its hash value.
The overridden get_action should be:
sub get_action {
my $self = shift;
my $actions = $self->{ACTIONS};
my $fks = $self->{FKS};
do_something
# if you get $action
return $action, $actions->{$action};
# or after you have modified the attributes, pass to SUPER
return $self->SUPER::get_action(@_);
}
Note that get_action runs at Phase 6 in the life circle, before the data collection, ACL and RLS. So at the time of this method, $self->{ARGS} is empty. If you’d like to change something in the 3 later phases, which you can’t access directly, you may do some data manipulations here.
