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); orSpecify
__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.
Module Install Instructions
To install DBIx::Class, copy and paste the appropriate command in to your terminal.
cpanm DBIx::Class
perl -MCPAN -e shell install DBIx::Class
