如何使用Devise和Ruby on Rails记录用户注册的IP地址？ [英] How to record the IP address a user signed up with using Devise and Ruby on Rails?

问题描述

我尝试了以下内容：

在 user.rb 中：

before_create :record_sign_up_ip

protected
def record_sign_up_ip
  self.sign_up_ip = current_sign_in_ip
end

不幸的是，虽然 current_sign_in_ip 有我正确的本地ip 127.0.0.1 ， sign_up_ip 保持为 nil 。如何轻松获得有人注册的IP？通常我会把它放在创建控制器中，但是使用Devise，没有控制器用于 User 。

Unfortunately, although current_sign_in_ip has my correct local ip of 127.0.0.1, sign_up_ip remains as nil. How can I easily get the IP of someone signing up? Normally I would put this in the create controller, but with Devise, there is no controller for User.

推荐答案

覆盖Devise使用的控制器，如覆盖设计注册控制器

Override the controller used by Devise as noted at Override devise registrations controller

从该帖子修改后，创建app / controllers / users / registrations_controller.rb：

As modified from that post, create app/controllers/users/registrations_controller.rb:

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

  def create
    params['user']['sign_up_ip'] = request.env['REMOTE_ADDR']   
    super
  end

end 

也从该帖子修改，使用该控制器：

Also modified from that post, to use that controller:

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

您还需要使sign_up_up可访问（对于Rails 3）：

You also need to make sign_up_up accessible (for Rails 3):

# app/models/user.rb
  attr_accessible :sign_up_ip
