I'm new to Devise and have it working fine by using an email address as the authentication
key. However, I have a use case which requires a username instead and I can't seem to get it working.
I've added a string column, "username" to the users table, changed the fields from :email to :username in the sign-in form, and have changed the authentication
key in devise.rb to :username yet when I go to sign in I'm met with this prompt: "Please enter an email address".
What am I doing wrong?
**new.html.erb**
<div><%= f.label :username %><br />
<%= f.email_field :username %></div>
**User.rb**
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :authentication_keys => [:username]
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me, :username
# attr_accessible :title, :body
end
**devise.rb**
config.authentication_keys = [ :username ]
