NAME Dancer2::Session::DBIC - DBIx::Class session engine for Dancer2 VERSION 0.120 DESCRIPTION This module implements a session engine for Dancer2 by serializing the session, and storing it in a database via DBIx::Class. JSON was chosen as the default serialization format, as it is fast, terse, and portable. SYNOPSIS Example configuration: session: "DBIC" engines: session: DBIC: 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 password: "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 serializer: "YAML" # defaults to JSON Or if you are already using Dancer2::Plugin::DBIC and want to use its existing configuration for a database section named 'default' with all else set to default in this module then you could simply use: session: "DBIC" engines: session: DBIC: db_connection_name: default 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. ATTRIBUTES schema_class DBIx::Class schema class, e.g. Interchange6::Schema. db_connection_name The Dancer2::Plugin::DBIC database connection name. If this option is provided then "schema_class", "dsn", "user" and "password" are all ignored. resultset DBIx::Class resultset, defaults to Session. id_column Column for session id, defaults to sessions_id. If this column is not the primary key of the table, it should have a unique constraint added to it. See "add_unique_constraint" in DBIx::Class::ResultSource. data_column Column for session data, defaults to session_data. dsn DBI dsn to connect to the database. user Database username. password Database password. schema DBIx::Class schema. serializer Serializer to use, defaults to JSON. Dancer2::Session::DBIC provides the following serializer classes: JSON - Dancer2::Session::DBIC::Serializer::JSON Sereal - Dancer2::Session::DBIC::Serializer::Sereal YAML - Dancer2::Session::DBIC::Serializer::YAML If you do not use the default JSON serializer then you might need to install additional modules - see the specific serializer class for details. You can also use your own serializer class by passing the fully-qualified class name as argument to this option, e.g.: MyApp::Session::Serializer serializer_object Vivified "serializer" object. serialize_options Options to be passed to the constructor of the serializer class as a hash reference. deserialize_options Options to be passed to the constructor of the deserializer class as a hash reference. METHODS _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. Dies if the session was found, but could not be deserialized. _change_id( $old_id, $new_id ) Change ID of session with $old_id to <$new_id>. _destroy() Remove the current session object from the database.
