NAME

6       DBIx::Class::ResultClass::HashRefInflator - Get raw hashrefs from a
7       resultset
8

SYNOPSIS

10        use DBIx::Class::ResultClass::HashRefInflator;
11
12        my $rs = $schema->resultset('CD');
13        $rs->result_class('DBIx::Class::ResultClass::HashRefInflator');
14        while (my $hashref = $rs->next) {
15          ...
16        }
17
18         OR as an attribute:
19
20        my $rs = $schema->resultset('CD')->search({}, {
21          result_class => 'DBIx::Class::ResultClass::HashRefInflator',
22        });
23        while (my $hashref = $rs->next) {
24          ...
25        }

DESCRIPTION

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

METHODS

45   inflate_result
46       Inflates the result and prefetched data into a hash-ref (invoked by
47       DBIx::Class::ResultSet)
48

CAVEATS

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.
