身份验证失败：omniauth

Question

我正在按照 omniauth-facebook 的以下教程在我的 rails 应用程序中配置来自 facebook 的身份验证方法：

http://railscasts.com/episodes/360-facebook-authentication

一切正常 运行 但回调后出现以下错误：

undefined method `from_omniauth' for #<Class:0x007ff05a58de30>

和代码片段：

class SessionsController < ApplicationController
  def create
    user = User.from_omniauth(env["omniauth.auth"]) #Highligted line as red
    session[:user_id] = user.id
    redirect_to root_url
  end

以下是我的 session_controller 文件：

class SessionsController < ApplicationController
  def create
    user = User.from_omniauth(env["omniauth.auth"])
    session[:user_id] = user.id
    redirect_to root_url
  end

  def destroy
    session[:user_id] = nil
    redirect_to root_url
  end
end

型号（user.rb）

class User < ActiveRecord::Base
  def self.from_omniauthsk(auth)
    where(auth.slice(:provider, :uid)).first_or_initialize.tap do |user|
      user.provider = auth.provider
      user.uid = auth.uid
      user.name = auth.info.name
      user.oauth_token = auth.credentials.token
      user.oauth_expires_at = Time.at(auth.credentials.expires_at)
      user.save!
    end
  end
end

Gem我用的是

gem 'omniauth-facebook'

Answer 1

你只是打错了：

from_omniauthsk 

应该是

from_omniauth
