问题描述
我正在编写一个 Rake 任务.我想在每个月的最后一个星期日晚上 11 点触发它.
I am writing a Rake task. I want to trigger it every last sunday of every month at 11 pm.
我如何使用 Ruby on Rails 中的 Every gem 来安排这个?
How can I schedule this using the Whenever gem in Ruby on Rails?
我的 rake 任务位于以下位置:app/lib/tasks/my_task.rake
I have my rake task in the following location: app/lib/tasks/my_task.rake
task :create_entries => :environment do
puts "Hello"
end
推荐答案
我不认为一个月的最后 x 天"有规则,但您总是可以进行额外的 if
测试块内:
I don't think there's a rule for "last x day of the month" but you can always put an extra if
test inside the block:
every :sunday, :at => '11pm' do
#if the month is different a week from now, we must be in the last
#sunday of the month
if Time.now.month != 1.week.from_now.month
rake "my:rake:task"
end
end
所以,这个预定的代码会在每个星期天运行,但只有在时间满足进一步的条件时才会继续调用 rake 任务.
So, this scheduled code will run every sunday, but it will only go on to call the rake task if the time meets the further conditions.
