如何在Rails 3 + Devise中创建访客用户 [英] how to create a guest user in Rails 3 + Devise

问题描述

目前我有一个rails 3应用程序与设计。它需要用户注册/登录才能访问。

我想启用访客用户。因此，当用户访问某些视图时，会为该用户创建访客用户帐户，然后如果/当他们验证/注册该访客用户时，升级到普通用户。

<将应用程序视为聊天室。我想让访客用户能够加入聊天室，然后再进入twitter进行注册。但是我不想在加入之前强迫用户注册。

建议？

我发现这个： https://github.com/plataformatec/devise/wiki/How-To:-Create-a-guest-user

问题是我添加了助手，但不明白如何启动current_or_guest_user。也不知道如何启动每个特定的允许的观点？

任何想法？指针？谢谢

解决方案

另一种更透明的方式是：

  def current_user 
 super || guest_user 
 end 
 
 private 
 
 def guest_user 
 User.find（session [：guest_user_id] .nil？？session [：guest_user_id] = create_guest_user。 id：session [：guest_user_id]）
 end 
 
 def create_guest_user 
u = User.create（：name =>guest，：email =>guest _ Time.now.to_i}＃{rand（99）} @ example.com）
 u.save（：validate => false）
u 
 end 
  

currently I have a rails 3 app with devise. it requires the users to register / signin for access.

I would like to enable guest users. So that when a user visits certain views a guest user account is created for that user and then if/when they authenticate/register that guest user is then upgraded to a normal user.

Think of the app as a chat room. I want guest users to be able to join the chat room, then later oauth into twitter to register. But I don't want to force users to register before joining.

Suggestions?

I found this: https://github.com/plataformatec/devise/wiki/How-To:-Create-a-guest-user

Problem with that is I added the helper, but don't understand how to initiate current_or_guest_user. Also not sure how to initiate per specific allowed views?

Any ideas? Pointers? Thanks

解决方案

Another more transparent way is this:

def current_user
  super || guest_user
end

private

def guest_user
 User.find(session[:guest_user_id].nil? ? session[:guest_user_id] = create_guest_user.id : session[:guest_user_id])
end

def create_guest_user
  u = User.create(:name => "guest", :email => "guest_#{Time.now.to_i}#{rand(99)}@example.com")
  u.save(:validate => false)
  u
end
