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:

       o   Specify "$rs->result_class" on a specific resultset to affect only that resultset (and any chained off of it); or

       o   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

       o   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.

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

NAME

       DBIx::Class::Manual::ResultClass - Representing a single result (row) from a DB query

SYNOPSIS

	 package My::Schema::Result::Track;

	 use parent 'DBIx::Class::Core';

	 __PACKAGE__->table('tracks');

	 __PACKAGE__->add_columns({
	   id => {
	     data_type => 'int',
	     is_auto_increment => 1,
	   },
	   cd_id => {
	     data_type => 'int',
	   },
	   title => {
	     data_type => 'varchar',
	     size => 50,
	   },
	   rank => {
	     data_type => 'int',
	     is_nullable => 1,
	   },
	 });

	 __PACKAGE__->set_primary_key('id');
	 __PACKAGE__->add_unique_constraint(u_title => ['cd_id', 'title']);

DESCRIPTION

       In DBIx::Class, a user normally receives query results as instances of a certain "Result Class", depending on the main query source.
       Besides being the primary "toolset" for interaction with your data, a "Result Class" also serves to establish source metadata, which is
       then used during initialization of your DBIx::Class::Schema instance.

       Because of these multiple seemingly conflicting purposes, it is hard to aggregate the documentation of various methods available on a
       typical "Result Class". This document serves as a general overview of "Result Class" declaration best practices, and offers an index of the
       available methods (and the Components/Roles which provide them).
