如何使用Rufus Scheduler安排日常工作

Question

I am trying to schedule a daily job using Rufus Scheduler. Is this a correct way doing it?

require 'rufus-scheduler'

scheduler = Rufus::Scheduler.new

scheduler.every '1d' do
  # Daily job code
end

Or should I create a cron job ? Cannot find anything in Rufus documentation.

Is this a correct way doing it ?

Yes, it is a correct way of doing it.

Or should I create a cron job ?

It depends on what you are building.

Doing

scheduler.every '1d' do
  # ...
end

will schedule now and then again in now + 24 * 3600 seconds and then again in now + 2 * 24 * 3600 seconds...

Doing

scheduler.cron '0 2 * * *' do
  # ...
end

will schedule every day at 2am.

Some people prefer the certainty of having some admin jobs run while the system is less busy (hence my example choice of 2am).

The rufus-scheduler documentation is explaining both and trusting you to choose the one that fits your requirements.
