使用时钟进程运行 Rake 任务

Question

在我的 Heroku 应用程序中，我有一个需要定期执行 rake 任务的时钟进程。我正在使用时钟 gem。这是 lib/clock.rb 中的代码：

require File.expand_path('../../config/boot',        __FILE__)
require File.expand_path('../../config/environment', __FILE__)
require 'clockwork'

include Clockwork

every(1.day, 'API Data Fetching', :at => '18:31') { `rake build_index` }

这里是 Heroku 日志 sn-p：

没有执行任务，也没有获取 API 数据。可能是什么问题？从 clock.rb 运行 rake 任务是个坏主意吗？

长时间后回答 :) 但您需要添加 Procfile 以使用 heroku this question 工作时钟工作宝石可能会帮助您。
