Answer 1

Answer is now outdated [ Valid for rails4 ]

I have done the same. Please follow these steps:

1. rails generate migration add_username_to_users username:string:uniq

2. rake db:migrate

3. add attr_accessible :username

4. in application_controller.rb:

   before_action :configure_permitted_parameters, if: :devise_controller?
   
   protected
   def configure_permitted_parameters
      devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password, :password_confirmation, :remember_me) }
      devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:login, :username, :email, :password, :remember_me) }
      devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:username, :email, :password, :password_confirmation, :current_password) }
   end 
   

5. in config/initializers if you want to replace email by usernname

   config.authentication_keys = [ :username ]
   config.case_insensitive_keys = [ :username ]  
   config.strip_whitespace_keys = [ :username ]
   

6. update the views.

Note if attr_accessible :usernamegives error try attr_accessor :username

If you are using rails 4 then put below code in application controller

class ApplicationController < ActionController::Base
 before_action :configure_permitted_parameters, if: :devise_controller?

 protected

 def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_up) << :username
 end
end

If you are using rails 4 then follow this steps:

1. rails g migration AddUserNameToAuthorize

2. rake db:migrate

3. put this code in application_controller.rb to accept username parameter for sign_in, sign_up and also for account_update:

   class ApplicationController < ActionController::Base
       protect_from_forgery with: :exception
       def configure_permitted_parameters
         devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email, :password,:username) }
         devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password, :password_confirmation,:username) }
         devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:email, :password, :password_confirmation,:username) }
       end
   end

Devise actually add the field to model which you specified during devise setup. If You have add migration to that model. For example, you have used devise for user model, then you can generate migration for adding the username to user model and run the db:migrate and add the attr_accessible :username to model, if you are using rails < 4
