【问题描述】:
我正在使用带有 Omniauth 的 Devise 让用户使用 Facebook 登录我的应用程序。我使用 Railscast 教程来启动和运行它。
如果用户已经是我网站的成员,则通过 facebook 进行身份验证可以正常工作。使用 facebook 对新用户进行身份验证时会出现问题。当它为我的用户模型创建新用户时,我收到“users.encrypted_password 可能不是 NULL”错误。我不知道如何将密码从 Facebook 信息传递给 User 模型。
这就是我所拥有的:
authentations_controller.rb
class AuthenticationsController < ApplicationController
def index
@authentications = current_user.authentications if current_user
end
def create
omniauth = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
if authentication
flash[:notice] = "Signed in successfully."
sign_in_and_redirect(:user, authentication.user)
elsif current_user
current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid'])
flash[:notice] = "Authentication successful."
redirect_to authentications_url
else
user = User.new
user.apply_omniauth(omniauth)
if user.save
flash[:notice] = "Signed in successfully."
sign_in_and_redirect(:user, user)
else
session[:omniauth] = omniauth.except('extra')
redirect_to new_user_registration_url
end
end
end
用户.rb
def apply_omniauth(omniauth)
self.email = omniauth['user_info']['email'] if email.blank?
authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid'])
end
def password_required?
(authentications.empty? || !password.blank?) && super
end
任何帮助都会很棒,在此先感谢!
