One revelation I had recently which I don't think has been mentioned
anywhere (at least not that I recall) is that when using DBIC and
Catalyst, *everything* is treated as a scalar. (is this a true
statement?) So in other words,
my $people = $c->model('AddressDB::People')
instead of
my @people = $c->model('AddressDB::People')
Assuming that AddressDB::People is a DBIx::Class-based model, then
my $people = $c->model('AddressDB::People')
will get you a DBIx::Class::ResultSet object, which is an object. You
can then use that object to iterate over the resultset or chain
another search on it.
my @people = $c->model('AddressDB::People')
will get you an array of row objects, which are the values returned by
iterating over the resultset. It's the equivalent of $c-
>model('AddressBookDB::People')->all();
Catalyst just provides a thin wrapper around the model, so this
doesn't really have anything to do with Catalyst and is more the
behaviour of DBIx::Class.
