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

From their Wiki — How To: Allow users to sign in using their username or email address.

Answer 2

https://gist.github.com/867932 : One solution for everything. Sign in, forgot password, confirmation, unlock instructions.

Answer 3

Make sure you already added username field and add username to attr_accessible. Create a login virtual attribute in Users

1) Add login as an attr_accessor

# Virtual attribute for authenticating by either username or email
# This is in addition to a real persisted field like 'username'
attr_accessor :login

2) Add login to attr_accessible

attr_accessible :login

Tell Devise to use :login in the authentication_keys

Modify config/initializers/devise.rb to have:

config.authentication_keys = [ :login ]

Overwrite Devise’s find_for_database_authentication method in Users

# Overrides the devise method find_for_authentication
# Allow users to Sign In using their username or email address
def self.find_for_authentication(conditions)
  login = conditions.delete(:login)
  where(conditions).where(["username = :value OR email = :value", { :value => login }]).first
end

Update your views Make sure you have the Devise views in your project so that you can customize them

remove <%= f.label :email %>
remove <%= f.email_field :email %>
add <%= f.label :login %>   
add <%= f.text_field :login %>

Answer 4

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:

(An earlier answer had a broken link, which I believe was intended to link to this resource.)

Answer 5

def self.find_for_authentication(conditions)
  conditions = ["username = ? or email = ?", conditions[authentication_keys.first], conditions[authentication_keys.first]]
  # raise StandardError, conditions.inspect
  super
end

Use their example!
