rails + sideqik... How to perform a task at a specific date and time

Question

I am using https://github.com/mperham/sidekiq gem in a rails app to schedule tasks at a specific date and time.. Ex: Send appointment reminder 10minutes before the appointment schedule time.

class TextWorker
include Sidekiq::Worker

    def perform(appointer_id)
        number = Usermodel.find_by_id(appointer_id).contact
        Message.create(:from =>  email, 
                           :to =>   number,
                               :body => 'Thank you...Your appointment is at 10/1/2015 Sun, at 12pm')
    end

end

and calling it here in appointments controller:

class Appointments_controller

def create
    TextWorker.delay_until(10/20/2014, 13:40).perform_async(@user_contact)
end

delay_until doesn't work with specific date/time:

Is there any other way to perform a task at a specific date/time in sideqik? if so how? please

Answer 1

you could pass in the calculated difference in order to send what sidekiq expects

e.g. DateTime.parse("10/20/2014")-DateTime.now

so :

  delay_interval = DateTime.parse("10/20/2014")-DateTime.now
  TextWorker.delay_until(delay_interval).perform_async(@user_contact)
