NAME¶
DBIx::Class::Helper::Row::ProxyResultSetUpdate - Efficiently reuse ResultSet
updates from results
SYNOPSIS¶
ResultSet:
package MyApp::Schema::ResultSet::Foo;
use base 'DBIx::Class::ResultSet';
sub update {
my ($self, $data) = @_;
die 'you fool!' if $data->{name} eq 'fool';
return $self->next::method($data);
}
Result:
package MyApp::Schema::Result::Foo;
use base 'DBIx::Class::Core';
__PACKAGE__->load_components(qw( Helper::Row::ProxyResultSetUpdate ));
...
or with DBIx::Class::Candy:
package MyApp::Schema::Result::Foo;
use DBIx::Class::Candy -components => ['Helper::Row::ProxyResultSetMethod'];
...
DESCRIPTION¶
This module makes reusing resultset updates from a result trivially easy. Often
the only way that people share update methods is by overriding update in their
resultset to use "update_all" in DBIx::Class::ResultSet.
Unfortunately, that can end up being wildly inefficient. Instead, if you can
write your update in terms of the resultset, you can make your code much
faster and more efficient.
