操作方法：设计 after_sign_up_redirect？

Question

我尝试按照此处 (GitHub Devise Wiki) 的说明进行操作，但对我不起作用。

我正在尝试让 Devise 在用户注册后重定向到 /welcome。我创建了一个 Registrations 控制器，但它永远不会进入视图。我在这里做错了什么？

红宝石 1.9.2 导轨 3.1.0.rc4 设计 1.4.2

谢谢

更新：

由于某种原因，after_sign_up_path_for 未被触发，但 after_sign_in_path_for 被触发。我仍然想让 after_sign_up_path_for 工作

_app/controllers/registrations_controller.rb_

class RegistrationsController < Devise::RegistrationsController
  protected

  def after_sign_up_path_for(resource)
    welcome_path
  end
end

这是我的 config/routs.rb

MyApp::Application.routes.draw do
  devise_for :users

  root :to => 'pages#home'

  match "/users", :to => "users#all"
  match "/users/:id", :to => "users#show", :as => :user

  match "/welcome", :to => "users#welcome", :as => :user

  devise_for :users, :controllers => { :registrations => "registrations" } do
    get "/login", :to => "devise/sessions#new"
    get "/register", :to => "devise/registrations#new"
    get "/logout", :to => "devise/sessions#destroy"
    get '/account' => 'devise/registrations#edit'
  end
end

rake 路线的输出

Answer 1

您的 routes.rb 中有两次 devise_for :users。修改 routes.rb 如下：

MyApp::Application.routes.draw do
  devise_for :users, :controllers => { :registrations => "registrations" } do
    get "/login", :to => "devise/sessions#new"
    get "/register", :to => "devise/registrations#new"
    get "/logout", :to => "devise/sessions#destroy"
    get '/account' => 'devise/registrations#edit'
  end

  root :to => 'pages#home'

  match "/users", :to => "users#all"
  match "/users/:id", :to => "users#show", :as => :user

  match "/welcome", :to => "users#welcome", :as => :user

end

如果你有激活/停用逻辑，你必须覆盖after_inactive_sign_up_path_for，正如设计维基中提到的那样。你能告诉注册后它被重定向到哪里吗？

after_sign_in_path_for工作的原因可能是你有相同的sessions_controller和不同的registrations_controller，所以登录如你所愿，注册路由被阻塞，因为你已经定义了两次，所以所有的注册请求并且动作在设计/注册而不是您的自定义注册控制器中执行。

所以删除它，改变上面提到的 routes.rb，看看会发生什么。

Answer 2

您的devise_for 看起来有点奇怪。 after_sign_up_path_for 应该可以作为 application_controller.rb 中的公共方法使用

将您的路线文件更改为devise_for :users，并将after_sign_up_path_for 放在您的application_controller.rb 中

Answer 3

您的 routes.rb 文件中有重复的 devise_for 列表。尝试删除第一个，简单的 devise_for :users，只留下第二个。

Answer 4

在我的应用程序中，我的application_controller.rb 文件中有after_sign_in_path_for 方法。试着把它放在那里，重新启动你的服务器，看看是否有什么不同。另外，我没有在protected 下列出我的方法，而是在private 下列出。

Answer 5

如果您想在注册后将用户重定向到欢迎页面，听起来您只是想在成功创建用户后重定向他们。所以你的 users_controller 看起来像这样：

class UsersController < ApplicationController
  def new  
      @user = User.new  
  end  

  def create  
    @user = User.new(params[:user])  
    if @user.save
      flash[:notice] = "Registration successful."  
      redirect_to welcome_path  
    else  
      render :action => 'new'  
    end  
  end

  def show
    @user = User.find(params[:id])
  end

  def edit
    @user = User.find(params[:id])
  end

  def update
    @user = User.find(params[:id])
    if @user.update_attributes(params[:user])
      flash[:notice] = "Successfully updated user."
      redirect_to @user
    else
      render :action => 'edit'
    end
  end
end

Answer 6

说明对我来说效果很好（新的注册控制器，修改 routes.rb 并将注册视图复制到 app/view/registrations），但我需要稍微更改我的 routes.rb 以便获取注册控制器。顺序很重要，因为将使用第一个匹配路由 - 您希望它成为新的注册路由。

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

devise_for :users

（确保 devise_for :users 出现在新的注册路径之后）
