Class: ActiveRecord::SessionStore::SqlBypass

Class | ActiveRecord::SessionStore::SqlBypass
In: | lib/active_record/session_store.rb
Parent: | Object

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.

### Methods

connection create_table! data destroy drop_table! find_by_session_id loaded? marshal new new_record? save unmarshal

### Attributes

data | [W] |
session_id | [R] |

### Public Class methods

connection()
create_table!()
drop_table!()
find_by_session_id(session_id)

Look up a session by id and unmarshal its data if found.

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)

### Public Instance methods

data()

Lazy-unmarshal session state.

destroy()
loaded?()
new_record?()
save()
