路由错误未初始化的常量用户
我是一个铁杆新手…我正在尝试设置登录Facebook的演示应用程序。 我正在使用OmniAuth并遵循本教程
https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview
重定向到fB时出现此错误：
Routing Error: uninitialized constant Users Try running rake routes for more information on available routes. 环境
Windows 7 Rails version :3.2.9.rc2 omniauth-1.1.1 devise-2.1.2
我的routes.rb看起来像这样：
root :to => 'static_pages#home' resources :users get "static_pages/home" match '/auth/facebook' => 'omniauth#passthru' match '/users/auth/facebook' => 'users/omniauth_callbacks#passthru' devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } , :strategy_class => OmniAuth::Strategies::Facebook
devise.rb包含：
require 'devise/orm/active_record' require 'omniauth-facebook' config.omniauth_path_prefix = "/users/auth" config.omniauth :facebook, "ABC", "XYZ",{:client_options => { :ssl => { :verify => false } }}
OmniAuthController包含：ie app / controllers / omniauth_callbacks_controller.rb
class Users::OmniauthCallbacksController :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 redirect_to "static_pages_home" end end def passthru render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false # Or alternatively, # raise ActionController::RoutingError.new('Not Found') end end
User.rb模型包含：
class User 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 end end
跟踪：
在2012-11-23 22:39:32 -0800（facebook）开始获取127.0.0.1的GET“/ users / auth / facebook”。回调阶段已启动。
开始GET“/ users / auth / facebook / callback？

MV
应用程序/控制器/ omniauth_callbacks_controller.rb
至
应用程序/控制器/用户/ omniauth_callbacks_controller.rb
或改变
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
至
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
我相信这部分搞砸了：
match '/users/auth/facebook' => 'users/omniauth_callbacks#passthru'
很少测试，对你来说：
放在你看来：
<%= link_to users_auth_facebook_path, users_auth_facebook_path %>
并点击它，它也给出了同样的错误……
我相信你应该使用类似的东西（你在上面链接的wiki中提到的）：
devise_scope :user do get '/users/auth/:provider' => 'users/omniauth_callbacks#passthru' end
并使用passthru方法将操作委派给适当的私有/受保护方法，具体取决于params [：provider]值
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController def passthru send(params[:provider]) if providers.include?(params[:provider]) end protected def facebook raise "Implement me for facebook" end def twitter raise "Implement me for twitter" end private def providers ["facebook", "twitter"] end end
