NAME

       Catalyst::Plugin::Session::Store::DBIC - Store your sessions via DBIx::Class

SYNOPSIS

           # Create a table in your database for sessions
           CREATE TABLE sessions (
               id           CHAR(72) PRIMARY KEY,
               session_data TEXT,
               expires      INTEGER
           );

           # Create the corresponding table class
           package MyApp::Schema::Session;

           use base qw/DBIx::Class/;

           __PACKAGE__->load_components(qw/Core/);
           __PACKAGE__->table('sessions');
           __PACKAGE__->add_columns(qw/id session_data expires/);
           __PACKAGE__->set_primary_key('id');

           1;

           # In your application
           use Catalyst qw/Session Session::Store::DBIC Session::State::Cookie/;

           __PACKAGE__->config(
               # ... other items ...
               'Plugin::Session' => {
                   dbic_class => 'DBIC::Session',  # Assuming MyApp::Model::DBIC
                   expires    => 3600,
               },
           );

           # Later, in a controller action
           $c->session->{foo} = 'bar';

DESCRIPTION

       This Catalyst::Plugin::Session storage module saves session data in your database via
       DBIx::Class.  It's actually just a wrapper around
       Catalyst::Plugin::Session::Store::Delegate; if you need complete control over how your
       sessions are stored, you probably want to use that instead.

METHODS

   setup_finished
       Hook into the configured session class.

   session_store_dbic_class
       Return the DBIx::Class class name to be passed to "$c->model".  Defaults to
       "DBIC::Session".

   session_store_dbic_id_field
       Return the configured ID field name.  Defaults to "id".

   session_store_dbic_data_field
       Return the configured data field name.  Defaults to "session_data".

   session_store_dbic_expires_field
       Return the configured expires field name.  Defaults to "expires".

   session_store_model
       Return the model used to find a session.

   get_session_store_delegate
       Load the row corresponding to the specified session ID.  If none is found, one is
       automatically created.

   session_store_delegate_key_to_accessor
       Match the specified key and operation to the session ID and field name.

   delete_session_data
       Delete the specified session from the backend store.

   delete_expired_sessions
       Delete all expired sessions.

CONFIGURATION

       The following parameters should be placed in your application configuration under the
       "Plugin::Session" key.

   dbic_class
       (Required) The name of the DBIx::Class that represents a session in the database.  It is
       recommended that you provide only the part after "MyApp::Model", e.g. "DBIC::Session".

       If you are using Catalyst::Model::DBIC::Schema, the following layout is recommended:

       ·   "MyApp::Schema" - your DBIx::Class::Schema class

       ·   "MyApp::Schema::Session" - your session table class

       ·   "MyApp::Model::DBIC" - your Catalyst::Model::DBIC::Schema class

       This module will then use "$c->model" to access the appropriate result source from the
       composed schema matching the "dbic_class" name.

       For more information, please see Catalyst::Model::DBIC::Schema.

   expires
       Number of seconds for which sessions are active.

       Note that no automatic cleanup is done on your session data.  To delete expired sessions,
       you can use the "delete_expired_sessions" method with Catalyst::Plugin::Scheduler.

   id_field
       The name of the field on your sessions table which stores the session ID.  Defaults to
       "id".

   data_field
       The name of the field on your sessions table which stores session data.  Defaults to
       "session_data" for compatibility with Catalyst::Plugin::Session::Store::DBI.

   expires_field
       The name of the field on your sessions table which stores the expiration time of the
       session.  Defaults to "expires".

SCHEMA

       Your sessions table should contain the following columns:

           id           CHAR(72) PRIMARY KEY
           session_data TEXT
           expires      INTEGER

       The "id" column should probably be 72 characters.  It needs to handle the longest string
       that can be returned by "generate_session_id" in Catalyst::Plugin::Session, plus another
       eight characters for internal use.  This is less than 72 characters when SHA-1 or MD5 is
       used, but SHA-256 will need all 72 characters.

       The "session_data" column should be a long text field.  Session data is encoded using
       MIME::Base64 before being stored in the database.

       Note that MySQL "TEXT" fields only store 64 kB, so if your session data will exceed that
       size you'll want to use "MEDIUMTEXT", "MEDIUMBLOB", or larger. If you configure your
       DBIx::Class::ResultSource to include the size of the column, you will receive warnings for
       this problem:

           This session requires 1180 bytes of storage, but your database
           column 'session_data' can only store 200 bytes. Storing this
           session may not be reliable; increase the size of your data field

       See "add_columns" in DBIx::Class::ResultSource for more information.

       The "expires" column stores the future expiration time of the session.  This may be null
       for per-user and flash sessions.

       Note that you can change the column names using the "id_field", "data_field", and
       "expires_field" configuration parameters.  However, the column types must match the above.
