ruby-on-rails - 使用 rails 4 认证的根路由进行设计无法正常工作

Question

我正在尝试做的事情

如果他们没有登录，我想将用户发送到registrations#new 页面。

在您输入登录信息并单击提交后，我希望您被发送到registrations#show 页面。

怎么了

当您未登录时，它会将您发送到 registrations#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 block 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)

我似乎无法弄清楚。它确实让您登录，正如我所看到的，通过手动导航到不同的页面，但是 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，但似乎无法得到它。我使用的代码基于 this thread

我的代码

在我的应用程序 Controller 中，我有 before_filter :authenticate_user!
我的路线文件:

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

Answer 1

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

见prepend_before_filter正在设计registrations_controller.rb

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

添加 show对 prepend_before_filter :authenticate_scope! 采取行动

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

同时复制 devise registration的观点(编辑和新模板)到 /app/views/registrations/你可以制作一个文件 show.html.erb在 /app/views/registrations/个人资料页面的文件夹。

对于设计路线如下:

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，在 after_sign_in_path_for(resource) 中设置“路径”和 after_sign_out_path_for(resource_or_scope)在文件 application_controller.rb

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:我已经尝试过(制作示例应用程序)，它可以工作。登录时查看日志 here , 并注销 here
