我正在尝试在this guide
之后的应用中实施Facebook身份验证在Facebook上授权后，我得到以下内容：
Unknown action
The action 'facebook' could not be found for Devise::OmniauthCallbacksController
我在app / controller / users / omniauth_callbacks_controller.rb中实现的方法为：
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
def facebook
# You need to implement the method below in your model (e.g. app/models/user.rb)
@user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)
if @user.persisted?
sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
else
session["devise.facebook_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
end
我的回调路线是：
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
有什么我想念的吗？我该如何调试呢？
谢谢！

答案 0 :(得分：12)
解决了我错误设置的问题！我最初遵循了Devise的教程并将其添加到我的路线中：
devise_for :users
然后我按照omniauth教程并为回调添加了以下内容：
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
不知何故，这些必须是冲突的，因为简单地删除第一个记录点回调正确的方向（它一定是在寻找我分类为Devise :: OmniauthCallbacksController的Devise类）。
