Module: Authlogic::ORMAdapters::ActiveRecordAdapter::ActsAsAuthentic::Persistence

Defined in:
lib/authlogic/orm_adapters/active_record_adapter/acts_as_authentic/persistence.rb

Overview

Persistence

This is responsible for all record persistence. Basically what your Authlogic session needs to persist the record’s session.

Class Methods

  • forget_all! - resets ALL records remember_token to a unique value, requiring all users to re-login

  • unique_token - returns a pretty hardcore random token that is finally encrypted with a hash algorithm

Instance Methods

  • forget! - resets the record’s remember_token which requires them to re-login

Alias Method Chains

  • #{options[:password_field]} - adds in functionality to reset the remember token when the password is changed
