Extended by:

Overview

TokenAuthenticatable

Allows to connect through an unique identifier.

The strategy to generate the authentication token is up to you. You may either generate a token when a user is created:

before_create :reset_authentication_token

or you may change the token whenever a user is saved:

before_save :reset_authentification_token

or whenever its password is changed:

before_save :reset_authentication_token, :if => :encrypted_password_changed?

The strategy to invalidate the authentication token is also up to you. You may use a callback or one of the configuration options:

  • token_authentication_valid_for - number of seconds a token will be valid once created (defaults to nil);

  • reusable_authentication_token - false to destroy the token once it’s consumed (defaults to true).
