Class: AuthenticationsController

Inherits:
ApplicationController show all
Defined in:
app/controllers/authentications_controller.rb

Overview

AuthenticationController will handle OmniAuth-providers for an existing user. Since authentications are handled by the omni-gem all we need is index, create, and delete. There is no need to edit/update or show a single authentication.
