SYNOPSIS

use Plack::Builder;
use Plack::Middleware::Session;
use Plack::Session::Store::DBI;
my $app = sub {
return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];
};
builder {
enable 'Session',
store => Plack::Session::Store::DBI->new(
dbh => DBI->connect( @connect_args )
);
$app;
};
# set get_dbh callback for ondemand
builder {
enable 'Session',
store => Plack::Session::Store::DBI->new(
get_dbh => sub { DBI->connect( @connect_args ) }
);
$app;
};

# with custom serializer/deserializer
builder {
enable 'Session',
store => Plack::Session::Store::DBI->new(
dbh => DBI->connect( @connect_args )
# YAML takes its args in the opposite order
serializer => sub { YAML::DumpFile( reverse @_ ) },
deserializer => sub { YAML::LoadFile( @_ ) },
);
$app;
};
# use custom session table name
builder {
enable 'Session',
store => Plack::Session::Store::DBI->new(
dbh => DBI->connect( @connect_args ),
table_name => 'my_session_table',
);
$app;
};

DESCRIPTION

This implements a DBI based storage for session data. By default it will use Storable and MIME::Base64 to serialize and deserialize the data, but this can be configured easily.

This is a subclass of Plack::Session::Store and implements its full interface.

SESSION TABLE SCHEMA

Your session table must have at least the following schema structure:

    CREATE TABLE sessions (
        id           CHAR(72) PRIMARY KEY,
        session_data TEXT
    );

Note that MySQL TEXT fields only store 64KB, so if your session data will exceed that size you'll want to move to MEDIUMTEXT, MEDIUMBLOB, or larger.

AUTHORS

Many aspects of this module were partially based upon Catalyst::Plugin::Session::Store::DBI
