设计:注册失败时重定向? [英] Devise: redirect on sign up failure?

问题描述

我正在尝试重定向未通过注册表单的用户(例如，他们输入的用户名已被占用，他们将字段留空等...)

I'm trying to redirect users that have failed the sign up form (e.g. they entered a username that is already taken, they left a field blank, etc...)

我为登录表单失败的用户设置了自定义失败，代码如下:

I have custom failure set up for users that fail the sign in form, code below:

class CustomFailure < Devise::FailureApp 

   def redirect_url 
      root_path 
   end 

   def respond 
      if http_auth? 
      http_auth 
   else 
      redirect 
   end 
 end

但是，我一直不知道如何设置它以防止注册失败.理想情况下，我只想将它们重定向回/到 root_path，有什么想法吗?谢谢！

However, I've been stuck on how to set this up for sign up failure. Ideally I would just like to redirect them back/to root_path, any ideas? Thank you!

推荐答案

您可能需要继承 Devise::RegistrationsController 并覆盖 create 操作.只需从 here 复制 create 方法并修改保存失败时的重定向.

You will probably need to subclass Devise::RegistrationsController and override the create action. Just copy over the create method from here and modify the redirect on failure to save.

# app/controllers/registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController


  def create
    # modify logic to redirect to root url
  end


end 

更改您的路线以告诉 Devise 使用您的控制器:

Change your routes to tell Devise to use your controller:

# config/routes.rb
devise_for :users, :controllers => {:registrations => "registrations"}
