Devise + Facebook omniauth:找不到Devise::OmniauthCallbacksController的操作'facebook‘

Question

我在SO上发现了类似的帖子，但它们都没有帮助我解决这个问题。我的路由如下所示：

devise_for :users do
    post '/users' => 'registrations#create', :as => 'user_registration'
end
devise_for :users, :controllers => {:omniauth_callbacks => "users/omniauth_callbacks"}

我也尝试过：

devise_for :users, :controllers => {:omniauth_callbacks => "omniauth_callbacks"}

但我还是得到了

The action 'facebook' could not be found for Devise::OmniauthCallbacksController

我甚至尝试过重启服务器，但这对我没有帮助。我正在关注this tutorial。

omniauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
    def facebook
        @user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)

        if @user.persisted?
            puts @user.inspect
            flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Facebook"
            sign_in_and_redirect @user, :event => :authentication
        else
            session["devise.facebook_data"] = request.env["omniauth.auth"]
            redirect_to new_user_registration_url
        end
    end
end

Answer 1

将您的设计路线更改为

  devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } 

以确保它与您的控制器定义匹配。

Answer 2

检查你的路线。也许它们会生成两次。尝试：

devise_for :users, :controllers => {:omniauth_callbacks => "users/omniauth_callbacks"}
devise_scope :users do
  post '/users' => 'registrations#create', :as => 'user_registration'
end
