NAME

DBIx::Class::ResultSet::PgLog - ResultSet base class for DBIx::Class::PgLog

VERSION

version 0.1

SYNOPSIS

Either create your own resultset-classes for each audited result-class, and load PgLogs resultset-component:

package MySchema::ResultSet::MyAuditedSource;

use base "DBIx::Class::ResultSet"; # or use Moose and MooseX::NonMoose;

__PACKAGE__->load_components("ResultSet::PgLog");

Or set the default resultset-class in your Schema:

package MySchema;

use base "DBIx::Class::Schema";

...

__PACKAGE__->load_namespaces(
	default_resultset_class => "PgLog"
);

DESCRIPTION

This resultset class enables logging for database updates made by calling "delete" in DBIx::Class::ResultSet and "update" in DBIx::Class::ResultSet. This includes any updates made by methods which rely on the above, like "set_\$rel" in DBIx::Class::Relationship::Base.

If you want full logging in a relational database, you most likely want to use this component.

NOTE:

The current implementation enables logging in the resultset by simply delegating 'delete' and 'update' to 'delete_all' and 'update_all', which call the required triggers. As a result, a database query like

"DELETE FROM table WHERE id IN '1', '2', '3'"

will result in 3 atomic queries:

"DELETE FROM table WHERE id = '1'";
"DELETE FROM table WHERE id = '2'";
"DELETE FROM table WHERE id = '3'";

which is much slower. It is therefore recommended to use this module only for resultset classes where it is needed. Specifying this module as default resultset class is only recommended if logging is needed for all tables.

DBIx::Class::ResultSet OVERRIDDEN METHODS

delete

Calls "delete_all" in DBIx::Class::ResultSet to ensure that triggers defined by DBIx::Class::PgLog are run.

update

Calls "update_all" in DBIx::Class::ResultSet to ensure that triggers defined by DBIx::Class::PgLog are run.
