设计回调 [英] Devise call backs

问题描述

这是我想出的：

  Warden :: Manager.after_authentication do | user，auth，opts | 
 user.update_attribute（：currently_signed_in，true）
 end 
 
 Warden :: Manager.before_logout do | user，auth，opts | 
 user.update_attribute（：Currently_signed_in，false）
 end 
  

这是什么我来跟踪目前登录的用户。

解决方案

我不是专家，但我相信回调（hooks）在监狱长级别（Devise建在监狱长之上）。

after_set_user和before_logout在Warden应该为你做的伎俩，但还有其他选项列在 Warden :: Hooks

Does devise have call backs when a user signs in and out?

This is what I came up with:

Warden::Manager.after_authentication do |user,auth,opts|
  user.update_attribute(:currently_signed_in, true)
end

Warden::Manager.before_logout do |user,auth,opts|
  user.update_attribute(:currently_signed_in, false)
end

This is what I came with to track users that are currently signed in.

解决方案

I'm no expert but I believe the callbacks (hooks) are at the Warden level (Devise is built on top of Warden).

after_set_user and before_logout in Warden should do the trick for you but there are other options listed in Warden::Hooks
