delayed_job how to set .delay(run_at: from (attribute).time.from_now)

问题

I am using delayed_job successfully like:

 Mailer.delay(run_at: 1.minutes.from_now).my_mail(my model)

I would like to set the minutes with an attribute, in this case called :frequency . i have tried with :frequency/frequency:/(frequency)/[frequency][:frequency]

one of the errors I'm getting is

undefined method `minutes' for :frequency:Symbol

Is what I'm trying to do possible? or should i do something else? How should i do it? Thanks for your help.

回答1:

Try:

frequency = 10
"#{frequency}".to_i.minute.from_now
