NAME
    Dancer2::Session::DBIC - DBIx::Class session engine for Dancer2

VERSION
    0.004

DESCRIPTION
    This module implements a session engine for Dancer2 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"
        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

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.

  resultset
    DBIx::Class resultset, defaults to `Session'.

  id_column
    Column for session id, defaults to `sessions_id'.

  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.

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.

  _destroy()
    Remove the current session object from the database.
