Ruby on Rails登录后设计代码 [英] Ruby on Rails Devise code after login

问题描述

我有一个RoR应用程序使用Devise进行登录。当创建新的用户记录时，有一些代码被放在user.rb文件中作为一个after_create调用/宏/任何。我需要在每次登录后运行这段代码，而不是在创建新用户时运行。

有些Google Googling似乎有一个选择是将Warden回调放在devise.rb代码。我的问题是：

1. 这是对的，还是/或者有更好的方法？


2. 如果这是正确的方法...
   
   
   
   • 如果Warden :: Manager ...方法在Devise.setup的devise.rb或是吗？
   
   
   • 是否after_authentication我应该使用的回调？我只是检查一下基于用户名的目录是否存在，如果不存在，则创建它。
   
   

解决方案

只是子类 Devise的会话控制器，并将您的自定义行为放在那里：

 ＃config / routes .rb 
 devise_for：users，：controllers => {：sessions => custom_sessions} 
  

然后创建您的控制器：

 ＃app / controllers / custom_sessions_controller.rb 
 class CustomSessionsController< Devise :: SessionsController 
 before_filter：before_login，：only => ：create 
 after_filter：after_login，：only => ：创建
 
 def before_login 
 end 
 
 def after_login 
 end 
 end 
  

I have an RoR app using Devise for logins. There is some code that is executed when a new User record is created, by being put in the user.rb file as an after_create call/macro/whatever. I need to make this code run after each login, instead of running on new user creation.

With some Googling, it seems that one option is to place Warden callbacks in the devise.rb code. My questions are:

1. Is this right, and/or is there a better way to do this?
2. If this is the right approach ...
   • Should the Warden::Manager... method defs go in devise.rb inside of Devise.setup, or after it?
   • Is after_authentication the callback I should use? I'm just checking to see if a directory based on the user's name exists, and if not, creating it.

解决方案

Just subclass Devise's sessions controller and put your custom behaviour there:

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

And then create your controller like this:

# app/controllers/custom_sessions_controller.rb
class CustomSessionsController < Devise::SessionsController
  before_filter :before_login, :only => :create
  after_filter :after_login, :only => :create

  def before_login
  end

  def after_login
  end
end
