Question

In my User model, I have a method to display the time:

def display_time
    puts "Time is: #{Time.zone.now}"
end

I am setting Time.zone for each user in a before filter in the application controller, and then calling the display_time method:

def my_before_filter
    Time.zone = current_user.time_zone
    current_user.display_time
end

I am also setting Time.zone for each user in a loop in my rake task (an hourly cron job), and then calling the same method:

Users.all.each do |user|
    Time.zone = user.time_zone
    user.display_time
end

How can I ensure that the two time zone settings will not interfere with each other ?

I want the display_time method to always use the Time.zone set via the application controller, except when it is called from the cron task’s loop. How can I achieve this ?

Thanks in advance!

Answer 1

Make display_time take the time parameter.

def my_before_filter
  Time.zone = current_user.time_zone
  current_user.display_time(Time.zone.now)
end

# app/models/user.rb
def display_time(current_time)
  puts "Time is: #{current_time}"
end

From your rake task, send the current_time that you want.
