delay_job如何设置.delay（run_at：from（attribute）.time.from_now） [英] delayed_job how to set .delay(run_at: from (attribute).time.from_now)

问题描述

我正在成功使用delay_job，例如：

I am using delayed_job successfully like:

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

我想用属性设置分钟，在本例中为：frequency。
i尝试使用：frequency / frequency：/（frequency）/ [frequency] [：frequency]

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

我遇到的一个错误是

undefined method `minutes' for :frequency:Symbol

我想做的是可能的吗？还是我应该做别的事情？
我应该怎么做？
感谢您的帮助。

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

推荐答案

尝试：

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