不知道如何构建任务“ weeklydelete”

Question

因此，我正在尝试使用cron_job任务设置Heroku调度程序 ，并且在运行heroku run rake weeklydelete时遇到以下错误：

Don't know how to build task 'weeklydelete'

我的任务代码如下所示：

task :weeklydelete do
  set :output, "#{path}/log/cron.log"
  job_type :script, "'#{path}/script/:task' :output"

  every :sunday, at: "3:00 AM" do
  runner "Event.clear_expired"
  runner "Activity.clear_expired"
  end

end

本质上，我想删除一周前的活动和活动-每个星期日。

我究竟做错了什么？

更新：＃lib / tasks / deletion.rb

namespace :deletion do
  desc :weekly_delete => :environment do
    set :output, "#{path}/log/cron.log"
    job_type :script, "'#{path}/script/:task' :output"

    every :sunday, at: "3:00 AM" do
    runner "Event.clear_expired"
    runner "Activity.clear_expired"
  end
 end
end

并在控制台中称为：

heroku run deletion:weekly_delete -a appname

错误：

Running `rake weekly_delete` attached to terminal... up, run.4492
rake aborted!
Don't know how to build task 'weekly_delete'

Answer 1

将文件名从delete.rb更改为delete.rake

Answer 2

它必须是这样的：

# lib/tasks/deletion.rb
namespace :deletion do
  desc :weekly_delete => :environment do
    # ...
  end
end

您这样称呼它：

$ rake deletion:weekly_delete
