A:
Define a current_user method in your ApplicationController
class ApplicationController < ActionController::Base
helper_method :current_user
def current_user
# ...
# return an instance of User class
# can be just:
# @current_user ||= User.find(session[:user_id])
# if you set session[:user_id] when the user logs in
end
end
This way you can access current_user.id inside other controllers.

You don't answer the question because it's assume he use some authentication plugin

I didn't assume he's using any plugins. If he has a login action, he's keeping the `user_id` somewhere. This is everything I've assumed.

Yes, regardless of whether he's using an authentication plugin, it's still perfectly valid to define `current_user`, and more than likely he is using a plugin anyway.

A:
You need use session.
You put your user id in session after login
session[:user_id] = user.id
And in all of your controller you can fetch you userid from this session
User.find(session[:user_id])
