rails + sidekiq特定的日期和时间作业

Question

我们如何使用db time使用rails将作业添加到sidekiq中的特定日期和时间，我想在约会时间到来时发送电子邮件，那么什么是最好的方法呢？

Answer 1

You might refer to the native Active Job API introduce in rails 4.2 (which come in front of Sidekiq).

You build job with the rails API, you specify in conf file that you use sidekiq, and rails will put the job in sidekiq.

Advantages : You can switch to another enqueuing gem, easier to delay job at a specific date, you can perform after_action, which are normally in the professional version of Sidekiq.

See the tutorial to learn more about it : http://edgeguides.rubyonrails.org/active_job_basics.html

A quick example :

# Enqueue a job to be performed tomorrow at noon. MyJob.set(wait_until: Date.tomorrow.noon).perform_later(record)

Hope it help

Answer 2

Attach an appointment date (or even better a specific appointment notification datetime) to the appointment model.

Then have a background job queued every minute that checks for all the unsent notifications for close events (for instance events where the appointment notification is lower than 1 minute in the future and not sent yet) and for each appointment queue an email to be sent.

You may want to use sidekiq to queue the emails, and a cron system such as clockwork to enqueue a task on sidekiq to check every minute for notifications to be sent.
