20 my $rs = $schema->resultset('CD')->search({}, {

24 ...

28 DBIx::Class is faster than older ORMs like Class::DBI but it still
29 isn't designed primarily for speed. Sometimes you need to quickly
30 retrieve the data from a massive resultset, while skipping the creation
31 of fancy result objects. Specifying this class as a "result_class" for
32 a resultset will change "$rs->next" to return a plain data hash-ref (or
33 a list of such hash-refs if "$rs->all" is used).
34
35 There are two ways of applying this class to a resultset:
36
37 · Specify "$rs->result_class" on a specific resultset to affect only
38 that resultset (and any chained off of it); or
39
40 · Specify "__PACKAGE__->result_class" on your source object to force
41 all uses of that result source to be inflated to hash-refs - this
42 approach is not recommended.
43
45 inflate_result
46 Inflates the result and prefetched data into a hash-ref (invoked by
47 DBIx::Class::ResultSet)
48
50 · This will not work for relationships that have been prefetched.
51 Consider the following:
52
53 my $artist = $artitsts_rs->search({}, {prefetch => 'cds' })->first;
54
55 my $cds = $artist->cds;
56 $cds->result_class('DBIx::Class::ResultClass::HashRefInflator');
57 my $first = $cds->first;
58
59 $first will not be a hashref, it will be a normal CD row since
60 HashRefInflator only affects resultsets at inflation time, and
61 prefetch causes relations to be inflated when the master $artist
62 row is inflated.
63
64 · Column value inflation, e.g., using modules like
65 DBIx::Class::InflateColumn::DateTime, is not performed. The
66 returned hash contains the raw database values.
