Rails -> Devise -> how to access current_user from Module

Question

I'm currently using Rails 3.2.9 with devise 3.0.4

I can access Devise current_user in Controller without any problem.

However, when I'm trying to access current_user in Module as below and receive error.

c_time = DateTime.current.in_time_zone(current_user.local_timezone)

NameError (undefined local variable or method `current_user' for DateCalculator:Module):

It would be great if someone please advise what's the best way to access current_user from Module.

Many Thanks in advance.

Answer 1

试试这个而不是使用current_user对象

UserSession.find.user

Answer 2

If your module does something specific to current signed in user, your can follow this way

config/initializers/user_specific_time.rb
module Devise
    module Controllers
        module Helpers
            def user_specific_time
                c_time = DateTime.current.in_time_zone(current_user.local_timezone)
            end
        end
    end
end

There is a Gem called sentient_user it is a cheeky approach but it does exactly what you need ;) which is to have access to current logged in user, from view | Controller | Model etc

https://rubygems.org/gems/sentient_user
