It is very basic, it took code from Jrock's book :)

sub item_DELETE {

    my($self, $c) = @_;

    my $id = $c->stash()->{id};

    my $set = $c->model('MyAppDB::Item')->find({id => $id});

    if($set){
        $self->status_ok($c,
                         entity => mk_entity($set));
        $set->delete();
    }
    else{
        $self->status_not_found($c,
                                message => "Item not found");
    }
}
