RoR Devise: Sign in with username OR email

Question

What\'s the best way to enable users to log in with their email address OR their username? I am using warden + devise for authentication. I think it probably won\'t be too h

Answer 1

Platforma Tec (devise author) has posted a solution to their github wiki which uses an underlying Warden authentication strategy rather than plugging into the Controller:
