用rails 4设计认证的根路由不起作用

我想做什么

我想将用户发送到注册#new页面,如果他们没有登录。

输入登录信息并单击“提交”后,我希望您将其发送到注册#show页面。

怎么了

当您未登录时,它会将您发送到注册#new页面(到目前为止正确)。 但是当您提交登录表单时,它会通过重定向循环发送错误。 服务器的输出就是这个块一遍又一遍地重复:

Started GET "/" for 127.0.0.1 at 2013-09-25 02:31:59 -0400 Processing by RegistrationsController#new as HTML User Load (0.7ms) SELECT "users".* FROM "users" WHERE "users"."id" = 8 ORDER BY "users"."id" ASC LIMIT 1 Redirected to http://lvh.me:3000/ Filter chain halted as :require_no_authentication rendered or redirected Completed 302 Found in 2ms (ActiveRecord: 0.7ms) 

我似乎无法弄明白。 它会让您登录,因为我可以看到通过手动导航到其他页面,但经过authenticated根路径无法正常工作。 我在我的路线文件中尝试了几种不同的组合,似乎无法得到它。 我正在使用的代码基于此线程

我的代码

在我的应用程序控制器中,我有before_filter :authenticate_user!

我的路线档案:

 devise_for :users, :controllers => { :registrations => "registrations" } devise_scope :user do root to: "registrations#new" end authenticated :user do root to: "registrations#show", :as => "profile" end unauthenticated do root to: "registrations#new", :as => "unauthenticated" end 

首先,您应该自定义Devise::RegistrationsController (您可以添加文件app/controllers/registrations_controller.rb

并在devise registrations_controller.rb上查看prepend_before_filter

 prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ] prepend_before_filter :authenticate_scope!, :only => [:edit, :update, :destroy] 

show action添加到prepend_before_filter :authenticate_scope!

registrations_controller.rb

 class RegistrationsController < Devise::RegistrationsController prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ] prepend_before_filter :authenticate_scope!, :only => [:edit, :update, :destroy, :show] # GET /resource/sign_up def new super end # POST /resource def create super end # GET /resource/edit def edit super end def update super end # DELETE /resource def destroy super end def show end protected def after_sign_up_path_for(resource) after_sign_in_path_for(resource) end end 

同时将设计注册视图(编辑和新模板)复制到/app/views/registrations/ ,您可以在/app/views/registrations/文件夹中为配置文件页面创建文件show.html.erb

对于设计路线看起来像:

 devise_for :users, :skip => [:registrations] devise_for :users, :controllers => { :registrations => "registrations" } authenticated :user do devise_scope :user do root to: "registrations#show", :as => "profile" end end unauthenticated do devise_scope :user do root to: "registrations#new", :as => "unauthenticated" end end 

最后,您在文件application_controller.rb中的after_sign_in_path_for(resource)after_sign_out_path_for(resource_or_scope)中设置“路径”

 class ApplicationController < ActionController::Base protect_from_forgery private def after_sign_in_path_for(resource) # After you enter login info and click submit, I want you to be sent to the registrations#show page profile_path end def after_sign_out_path_for(resource_or_scope) new_user_session_path end end 

注意:我试过这个(制作示例应用程序),它可以工作。 登录时请查看日志,并在此处注销

重定向到registration#new是默认的,所以你需要做的就是这个(在路由文件中):

 devise_for :users, :controllers => { :registrations => "registrations" } devise_scope :user do root to: "registrations#show" # This is the root path of the user when you are logged in end unauthenticated do root to: "registrations#new", :as => "unauthenticated" end # I dont't think this part is neccesary... Try if it works without authenticated :user do root to: "registrations#show", :as => "profile" end 

不要使用路由来执行属于控制器的作业。

要在注册后将用户重定向到特定页面,请使用Devise内置的after_sign_up_path_for并覆盖它。

 class ApplicationController def after_sign_up_path_for(resource) faked_user_profile_path(resource) end end 

对于路由,除了devise_for部分之外,我并不是很了解所有这些devise_for 。 但是对于重定向function,这个重写应该足够了。
