如何在 users/sign_up 之后 redirect_to root？

Question

运行 Rails (v7.0.1), ruby (v3.0.1) 并将设计 gem 添加到 Gemfile。

我正在 localhost:3000/users/sign_up 上的浏览器中测试 users/sign_up 路由。它成功地将用户保存到数据库（postgresql）我想在 sign_up 之后 redirect_to root，就像 sign_in 当前所做的那样，但我得到的是：

Devise::RegistrationsController#create 中没有方法错误 #Devise::RegistrationsController:0x00000000032988 的未定义方法“user_url” 提取的源代码（大约第 231 行）： 229 230 231 232 233 234

        if options.empty?
          recipient.public_send(method, *args)
        else
          recipient.public_send(method, *args, options)
        end

这是堆栈跟踪：

NoMethodError (undefined method `user_url' for #<Devise::RegistrationsController:0x00000000032988>):

我尝试使用以下方法修改应用程序控制器：

ApplicationController.rb

def after_sign_up_path_for(:user)
 root_path
end

(https://github.com/heartcombo/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-in-out)

但运气不好。

也试过rails generate devise:controllers registrations公开必要的注册#create方法进行修补，但还没有破解 ()

Answer 1

您可以使用 after_sign_up_path_for 方法

创建自己的注册控制器作为设计注册控制器的子控制器

# app/controllers/registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController
  private

  def after_sign_up_path_for(resource)
    root_path # or any other path
  end
end

然后将此控制器添加到您通往 devise_for 的路线中，就像这样

# config/routes.rb

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