DBIx::Class::ResultClass::HashRefInflator::UTF8 - Get raw hashrefs from a resultset with utf-8 flag
version 1.000005
use DBIx::Class::ResultClass::HashRefInflator::UTF8;
my $rs = $schema->resultset('CD');
$rs->result_class('DBIx::Class::ResultClass::HashRefInflator::UTF8');
while (my $hashref = $rs->next) {
...
}
OR as an attribute:
my $rs = $schema->resultset('CD')->search({}, {
result_class => 'DBIx::Class::ResultClass::HashRefInflator::UTF8',
});
while (my $hashref = $rs->next) {
...
}
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:
$rs->result_class
on a specific resultset to affect only that
resultset (and any chained off of it); or__PACKAGE__->result_class
on your source object to force all
uses of that result source to be inflated to hash-refs - this approach is not
recommended.This module should be used to force UTF8 on your results in case your DBI/DBD/lib-$protocol pipeline does not support unicode natively (similar to the higher-level DBIx::Class::ForceUTF8).
Inflates the result and prefetched data into a hash-ref (invoked by DBIx::Class::ResultSet)
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::UTF8');
my $first = $cds->first;
$first
will not be a hashref, it will be a normal CD row since
HashRefInflator::UTF8 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.
