我正在关注 Railscast #235“Devise + OmniAuth Revised”,每当我尝试使用 Twitter 进行身份验证时,都会遇到用户名的 NoMethodError。我正在运行 Rails 3.2。

具体来说,它写道:

NoMethodError in OmniauthCallbacksController#twitter
undefined method `username' for #<User:0x007fa4744561c0>

app/models/user.rb:11:in `from_omniauth'
app/controllers/omniauth_callbacks_controller.rb:3:in `all'

我是 Rails 的新手,所以任何帮助将不胜感激。看看我的代码:

omn​​iauth_callbacks_controller:
    class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def all
user = User.from_omniauth(request.env["omniauth.auth"])
if user.persisted?
flash.notice = "Signed in!"
sign_in_and_redirect user
else
session["devise.user_attributes"] = user.attributes
redirect_to new_user_registration_url
end
end
alias_method :twitter, :all
end

用户模型:
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable, :omniauthable,
:recoverable, :rememberable, :trackable, :validatable

attr_accessible :email, :password, :password_confirmation, :remember_me, :username

validates_presence_of :username
validates_uniqueness_of :username

def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_create do |user|
user.provider = auth.provider
user.uid = auth.uid
user.username = auth.info.nickname
end
end

def self.new_with_session(params, session)
if session["devise.user_attributes"]
new(session["devise.user_attributes"], without_protection: true) do |user|
user.attributes = params
user.valid?
end
else
super
end
end

def password_required?
super && provider.blank?
end

def update_with_password(params, *options)
if encrypted_password.blank?
update_attributes(params, *options)
else
super
end
end
end
