A barebones session store which duck-types with the default session store but bypasses Active Record and issues SQL directly. This is an example session model class meant as a basis for your own classes.
The database connection, table name, and session id and data columns are configurable class attributes. Marshaling and unmarshaling are implemented as class methods that you may override. By default, marshaling data is
ActiveSupport::Base64.encode64(Marshal.dump(data))
and unmarshaling data is
Marshal.load(ActiveSupport::Base64.decode64(data))
This marshaling behavior is intended to store the widest range of binary session data in a text column. For higher performance, store in a blob column instead and forgo the Base64 encoding.

Class Method Detail
connection()
create_table!()
drop_table!()
find_by_session_id(session_id)
marshal(data)
new(attributes)
Look for normal and marshaled data, self.find_by_session_id‘s way of telling us to postpone unmarshaling until the data is requested. We need to handle a normal data attribute in case of a new record.
unmarshal(data)
Instance Method Detail
data()
Lazy-unmarshal session state.
