我是新手，试图使用omniauth & 2 和omniauth-facebook 将facebook 登录添加到我的rails 应用程序中。我按照https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview上的说明进行操作。

但它现在向我显示以下错误，我在网上搜索并尝试了许多不同的方法但没有取得多大成功，我不知道我做错了什么，所以有人可以帮我解决这个问题吗？非常感激。

继续运行

rails (3.2.12) 使用 oauth2 (0.8.1) 使用omniauth (1.1.4) 使用omniauth-oauth2 (1.1.1) 使用omniauth-facebook (1.4.1)

错误：ActiveRecord::RecordNotFound in UsersController#show 找不到 id=sign_up 的用户

我的代码

 class User < ActiveRecord::Base
 # Include default devise modules. Others available are:
 # :token_authenticatable, :confirmable,
 # :lockable, :timeoutable and :omniauthable
   devise :database_authenticatable, :registerable, :recoverable, :rememberable,                  :trackable, :validatable, :omniauthable, :omniauth_providers => [:facebook]

 # Setup accessible (or protected) attributes for your model
 attr_accessible :email, :password, :password_confirmation, :remember_me, :name, :provider, :uid, :name
 attr_accessible :title, :date_of_birth, :firstName, :lastName, :mailId, :phone, :provider, :uid

protected

 def self.find_for_facebook_oauth(auth, signed_in_resource=nil)
user = User.find(:provider => auth.provider, :uid => auth.uid).first
unless user
  user = User.create(name:auth.extra.raw_info.name,
                       provider:auth.provider,
                       uid:auth.uid,
                       email:auth.info.email,
                       password:Devise.friendly_token[0,20]
                       )
 end
 user
end  

def self.new_with_session(params, session)
super.tap do |user|
  if data = session["devise.facebook_data"] && session["devise.facebook_data"]["extra"]["raw_info"]
    user.email = data["email"] if user.email.blank?
  end
 end

  1. 从终端：

    bundle exec rake 路由 >> r.txt

  2. 打开 r.txt 并查找包含 的行users#show，记下该行的第一个术语，它应该类似于 user_show（我们称之为the_route）。

  3. 添加_path到您的路线（例如the_route_path）并在整个项目中搜索该字符串。

  4. 在你的项目中的某个地方（很可能在一个视图中）会有一个link_toorredirect_to the_route_path我猜你会在某个地方'sign_up'作为:id参数传递。

  5. 这就是错误所在。
