# DBIx::Class::ResultClass::HashRefInflator(3pm)

Get raw hashrefs from a resultset

## NAME

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

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.
