如何在Rails中创建一个任务以便将来运行一次？

I have a subscription-based site that allows unregistered users to download files if they give me their email. I want the following workflow.

我有一个基于订阅的网站，允许未注册的用户下载文件，如果他们给我他们的电子邮件。我想要以下工作流程。

1. User give email address

   用户提供电子邮件地址

2. Rails creates a task for 7 days in the future

   Rails将来会创建一个任务7天

3. User downloads emailed file

   用户下载电子邮件文件

4. If user hasn't signed up in 7 days, send user an email

   如果用户未在7天内注册，请向用户发送电子邮件

I need to add #2 and #4. Right now I'm using ActiveJob and Sidekiq to create jobs to send the download email. Is there a way I can create an ActiveJob to run in the future? And will that future job have access to my rails environment to check against my DB?

我需要添加＃2和＃4。现在我正在使用ActiveJob和Sidekiq创建作业以发送下载电子邮件。有没有办法让我可以创建一个ActiveJob来运行？未来的工作是否可以访问我的rails环境以检查我的数据库？

2 个解决方案

#1

Sure you can enqueue an ActiveJob to be performed in 1 week. In the job's implementation conditionally send an email if the user hasn't signed up. Refer to the Rails guides on ActiveJob: http://guides.rubyonrails.org/active_job_basics.html#enqueue-the-job

当然，您可以在一周内将ActiveJob排队。在作业的实施中，如果用户尚未注册，则有条件地发送电子邮件。请参阅ActiveJob上的Rails指南：http：//guides.rubyonrails.org/active_job_basics.html#enqueue-the-job

Example:

例：

# Enqueue a job to be performed 1 week from now.
UserConfirmationJob.set(wait: 1.week).perform_later(user)

#2

Can you do it this way:

你能这样做吗：

1. User gives the email.
2. 用户发送电子邮件。
3. You allow him to download.
4. 你允许他下载。
5. Every day you run a script to check that whether the user who gave his email 7 days ago has signed up or not.
6. 您每天都会运行一个脚本来检查7天前发送电子邮件的用户是否已注册。
7. And you send him an email if he hasn't signed up.
8. 如果他还没有注册，你就给他发电子邮件。
