Rails后台进程（Heroku Rails 3+）

Question

I'm am going to set up some functionality for my app that is Rails 3.2.3 and on Heroku. The idea is to have a task, or job (or whatever you want to call it) run every day, to make sure user information from the external API is up to date with the user information in my db. I'm curious what is the the best way to set this up? Should it be a cron job that runs a rake task?

Seems like there are quite a few ways to do this and I'm interested in the ways others are doing this. The only way I can think to do it is to run a rake task in a cron job, but would love to figure out what best practices are, or the most simple way to do it. Seems like there are a lot of ways to skin this cat... lots of different tools out there too.

If there was a pure rails way to do this, I think that would be better so I don't have to screw around with every system I place my app onto.

Answer 1

There are two options. They're better than options you mentioned in your question

1. Resque .
2. Sidekiq .

Try the later one. It is faster, lightweight and based on multithreading so there isn't interference with system. You'll need to look into scheduler of both the gem for processing everyday.

Hope this helps!

Answer 2

Use the Heroku scheduler add on to the handle scheduling itself. You can have it run a rake task, resque, or whatever.

Answer 3

For a simple sync job that runs once a day, I believe having a cronjob would be sufficient and likely more stable in the long run.

Honestly, solutions such as Resque and Sidekiq is a bit overkill in my opinion (for your needs). You're still required to use a scheduler to send messages to these systems.

Check out the gem ' whenever ' if you're looking at making the deployment and writing of crontabs easier: https://github.com/javan/whenever/

Answer 4

Here is a few to choose from :

1. resque (with resque-scheduler . But you have to use redis with it)
2. rufus-scheduler ( if you want something simple, resque uses rufus-scheduler itself)
3. You may try delayed_job with a few tricks like this one . Not that great for scheduling but can use your application database.
