ruby - 怎么在model里边获取当前用户的ID等信息

Question

想要做一个操作日志记录执行过的操作，
然后想在model里边获取当前操作用户的ID，进行操作的数据表名称，还有操作类型
现在写了一个moduel。

module RecordOperation
  extend ActiveSupport::Concern
  included do
    after_update :record_operation
    before_destroy :record_operation
    after_create :record_operation
    def record_operation

    end
end

Answer 1

This is what the design document says
To verify if a user is signed in, use the following helper:

user_signed_in?

For the current signed-in user, this helper is available:

current_user

You can access the session for this scope:

user_session

================================
As for the model, a direct way is to directly pass in the user instance or id in the method

I like redmine’s processing method better
User.rb

def self.current=(user)
    Thread.current[:current_user] = user
end

def self.current
  Thread.current[:current_user] ||= User.anonymous
end

Then in the login method

User.current = find_current_user
if user && user.is_a?(User)
  User.current = user
  start_user_session(user)
else
  User.current = User.anonymous
end

Finally User.current can be called anywhere to get an instance of the currently logged in person

In fact, I have not used design in depth, and I am not sure about its specific implementation.
I just got curious, so I will try it when I go back tonight
