【问题描述】：

我需要在 rails 4.2 应用程序中运行重复作业。我在任何时候安装 gem。

我创建 ActiveJob

class Analytics::CalculateAllJob < ActiveJob::Base
  queue_as :default

  def perform(*args)
    orgs = Org.all
    orgs.each do |org|
      org.departments
      Rails.logger.info "Scheduled a job to calculate Analytics"
    end
  end
end

我在 shedule.rb 中添加了 cron 作业

every 10.minutes do
  runner "Analytics::CalculateAllJob"
end

只要 -i 就运行命令。他将更改写入 crontab 我从命令行运行 cron 命令：

/bin/bash -l -c 'cd /home/www/myproject && bin/rails runner -e development '\''Analytics::CalculateAllJob'\'' >> /home/www/myproject/log/cron.log 2>&1'

得到

/home/www/.rvm/gems/ruby-2.2.0@rails420/gems/railties-4.2.0/lib/rails/commands/runner.rb:62:in `<top (required)>': uninitialized constant Analytics::CalculateAllJob (NameError)

from -e:1:in `<main>'

我做错了什么？

【问题讨论】：

标签： ruby-on-rails cron whenever

【解决方案1】：

您应该在调用perform 之前创建一个作业实例。

every 10.minutes do
  runner "Analytics::CalculateAll.new.perform_later"
end

【解决方案2】：

解决了。我的错误是调用类名。

工作代码：

app/jobs/analytics/calculate_all.rb

class Analytics::CalculateAll < ActiveJob::Base
  def perform(*args)
    ...
  end
end

config/shedule.rb

every 10.minutes do
  runner "Analytics::CalculateAll.perform_later"
end
