Question

我是新手试图使用omniauth＆amp; amp;添加facebook登录到我的rails应用程序2和omniauth-facebook。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，我已经在网上搜索并尝试了许多不同的方法而没有太大的成功，我不知道我做错了什么，所以我可以帮助我吗？非常感谢。

在

上运行

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： UsersController＃show中的ActiveRecord :: RecordNotFound 找不到具有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,

                       )
 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?

Answer 1

：

捆绑exec rake路线＆gt;＆gt; r.txt
打开r.txt并查找包含users#show的行，记下该行的第一个字词，它应该类似于user_show（让我们称之为the_route）。
将_path添加到您的路线（例如the_route_path）并在整个项目中搜索该字符串。
您项目中的某个位置（最有可能在视图中）会有link_to或redirect_to the_route_path，我猜您将在某处传递'sign_up'作为:id param。
这就是错误所在。
