groovy - Perl 5.8 cascading null checks -

let's have next groovy code:

string name = child.getparent()?.getparent()?.getname();

note getparent() may homecoming null, , in case code continues work without null pointer exceptions beingness thrown.

is there way in 1 line in perl 5.8? open writing generic helper method accomplish this.

i'm running situations have several nested objects , having like:

my $name = $child && $child->getparent && $child->getparent->getparent && $child->getparent->getparent->getname;

yes in 1 line, fugly imo.

in my opinion, original groovy code on boundary of readability anyway. implement rather differently, similar look in perl be

my $name = ( $node = $node->get_parent or $node = $node->get_parent or $node->get_name );

the utility of language isn't defined ability represent complex constructs in few characters

perl groovy null

python - How to add an model instance to a django queryset? - it seems django queryset behaves somehow python list. but doesn't back upwards list's .append() method know. what want like: from my_django_app.models import mymodel queryset = mymodel.objects.none() queryset.append(mymodel.objects.first()) ## no list's .append() method! is there way add together model instance existing queryset? no. queryset representation of query - hence name - not arbitrary collection of instances. if need actual queryset rather list, seek accumulating ids of objects need , getting objects via __in query: list_of_ids = [] list_of_ids.append(my_id) ... queryset = mymodel.objects.filter(id__in=list_of_ids) this isn't efficient, though. python django
