推荐答案

一个rake任务或后台作业（如Active作业或延迟工作）可以做的伎俩，但是你可能并不需要他们在这种情况下。如果你正在处理的时间戳在数据库中，您可以创建一个范围或一个方法，归档标记的工作。

A rake task or background job (such as Active Job or Delayed Job ) can do the trick however you might not need them in this case. If you are dealing with timestamps in your database, you can create a scope or a method to mark jobs as archived.

举例来说，如果你有一个名为列 approved_at 这是一个日期时间。当您批准工作，将 approved_at = Time.now 。

For instance, if you have a column named approved_at that is a datetime. When you approve a job, you set the approved_at = Time.now.

现在，您可以创建一个方法，表示如果作业存档：

Now you can create a method that indicates if the job is archived:

def is_archived?
  approved_at && approved_at < Time.now - 30.days
end

和让所有的归档工作，你可以创建一个范围：

And to get all the archived jobs, you can create a scope:

scope :archived, -> { where('approved_at IS NOT NULL AND approved_at <?', Time.now - 30.days)}
