NAME

CHI::Driver::DBIC - DBIx::Class Driver for CHI.

VERSION

Version 0.002

SYNOPSIS

This module allow the CHI caching interface to use a database as a backend via DBIx::Class.

It implements the methods which are required by a CHI::Driver: store, fetch, remove and clear. It should not be necessary to access these methods directly.

It should be noted that most database supported by DBIx::Class are slower than caches or NoSQL databases.

Example Object Creation

  $chi = CHI->new(
    driver             => 'DBIC',
    resultset          => $schema->resultset('Mbfl2Session'),
    expires_on_backend => 1,
    expires_in         => 30
  ),

Example get and set

  $val = $chi->get($key);

  $chi->set( $key, $val );

Example Table Definition (Oracle)

  SQL> desc mbfl2_sessions
   Name                                      Null?    Type
   ----------------------------------------- -------- ----------------------------
   ID                                        NOT NULL VARCHAR2(72)
   SESSION_DATA                                       BLOB
   EXPIRES                                            NUMBER

EXPORT
