NAME ^

Dancer::Session::DBIC - DBIx::Class session engine for Dancer

VERSION ^

0.003

DESCRIPTION ^

This module implements a session engine for Dancer by serializing the session, and storing it in a database via DBIx::Class. The default serialization method is JSON, though one can specify any serialization format you want. YAML and Storable are viable alternatives.

JSON was chosen as the default serialization format, as it is fast, terse, and portable.

SYNOPSIS ^

Example configuration:

    session: "DBIC"
    session_options:
      dsn:      "DBI:mysql:database=testing;host=127.0.0.1;port=3306" # DBI Data Source Name
      schema_class:    "Interchange6::Schema"  # DBIx::Class schema
      user:     "user"      # Username used to connect to the database
      pass: "password"  # Password to connect to the database
      resultset: "MySession" # DBIx::Class resultset, defaults to Session
      id_column: "my_session_id" # defaults to sessions_id
      data_column: "my_session_data" # defaults to session_data

In conjunction with Dancer::Plugin::DBIC, you can simply use the schema object provided by this plugin in your application:

    set session_options => {schema => schema};

Custom serializer / deserializer can be specified as follows:

    set 'session_options' => {
        schema       => schema,
        serializer   => sub { YAML::Dump(@_); },
        deserializer => sub { YAML::Load(@_); },
    };

SESSION EXPIRATION ^

A timestamp field that updates when a session is updated is recommended, so you can expire sessions server-side as well as client-side.

This session engine will not automagically remove expired sessions on the server, but with a timestamp field as above, you should be able to to do this manually.

METHODS ^

create()

Creates a new session. Returns the session object.

flush()

Write the session to the database. Returns the session object.

retrieve($id)

Look for a session with the given id.

Returns the session object if found, undef if not. Logs a debug-level warning if the session was found, but could not be deserialized.

destroy()

Remove the current session object from the database.
