DBIx::C...Inflator(3)

💖 NAME 💖

okay bestie, welcome to DBIx::C...Inflator(3) from the User Contributed Perl Documentation section — we're getting into some raw-hashref realness, and it's lowkey iconic. 💅✨

DBIx::Class::ResultClass::HashRefInflator — Get raw hashrefs from a resultset.

---

✨ SYNOPSIS ✨

use DBIx::Class::ResultClass::HashRefInflator;

my $rs = $schema->resultset('CD');
$rs->result_class('DBIx::Class::ResultClass::HashRefInflator');
while (my $hashref = $rs->next) {
  ...
}

OR as an attribute:

my $rs = $schema->resultset('CD')->search({}, {
  result_class => 'DBIx::Class::ResultClass::HashRefInflator',
});
while (my $hashref = $rs->next) {
  ...
}

---

🌸 DESCRIPTION 🌸

okay so real talk: DBIx::Class is faster than older ORMs like Class::DBI, but it still isn't designed primarily for speed. Sometimes you need to quickly retrieve the data from a massive resultset while skipping the creation of fancy result objects. Specifying this class as a result_class for a resultset will change $rs->next to return a plain data hash-ref — or a list of such hash-refs if $rs->all is used. 🫶

There are two ways of applying this class to a resultset:

• Specify $rs->result_class on a specific resultset to affect only that resultset (and any chained off of it); or
• Specify __PACKAGE__->result_class on your source object to force all uses of that result source to be inflated to hash-refs — this approach is not recommended. 🙈

🎀 METHODS 🎀

inflate_result

Inflates the result and prefetched data into a hash-ref (invoked by DBIx::Class::ResultSet). 💖

---

⚠️ CAVEATS ⚠️

• This will not work for relationships that have been prefetched. Consider the following:

my $artist = $artitsts_rs->search({}, {prefetch => 'cds' })->first;

my $cds = $artist->cds;
$cds->result_class('DBIx::Class::ResultClass::HashRefInflator');
my $first = $cds->first;

$first will not be a hashref, it will be a normal CD row since HashRefInflator only affects resultsets at inflation time, and prefetch causes relations to be inflated when the master $artist row is inflated. 😭

• Column value inflation, e.g., using modules like DBIx::Class::InflateColumn::DateTime, is not performed. The returned hash contains the raw database values. 💀
