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) {
    ...
 }

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 row 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 the DBIx::Class::ResultSet manpage)

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.
