用Rails安排任务 [英] Scheduling tasks with rails

问题描述

我一直在遍历rails调度任务选项，并从任何时候偶然发现这段代码.

I have been going over rails scheduling tasks options and stumbled upon this piece of code from whenever.

case @environment
when 'production'
every 1.day, :at => "#{Time.parse('12:00 A').getlocal.strftime("%H:%M")}" do
   runner "Company.send_later(:create_daily_stories!)"
end 
when 'staging'
  every 15.minutes do
   command "thinking_sphinx_searchd  reindex"
  end
end

我对红宝石还很陌生，我不太了解公司"在这里的含义.换句话说，我想向人们发送电子邮件，并且我有一个名为email_controller的控制器类，其中有一个名为sendEmail的方法，我想使用此方法发送电子邮件吗?我应该说跑步者"email_controller.sendEmail"还是类似的东西?我不太明白.注-我是否使用模型或控制器代替公司?

I am fairly new to ruby and I dont quite understand what "Company" here stands for. In other words say i want to send an email out to people and i have a controller class called email_controller in which I have a method called sendEmail and I want to send emails using this how would i do it? Should i say runner"email_controller.sendEmail" or something like that? I dont quite get it. Note - Do i use the model or controller in place of company?

推荐答案

在这种情况下，Company是一个示例模型，该模型具有称为create_daily_stories!的类/单个方法.从理论上讲，它可能看起来像这样:

In this case, Company is an example model that has a class/singleton method called create_daily_stories!. In theory, it would probably look like this:

class Company < ActiveRecord::Base

  # Send out daily stories to all companies
  def self.create_daily_stories!
    # Do some stuff
  end
end

理想情况下，生成电子邮件驻留在业务逻辑中，因此应包含在模型中(假设您使用的是Rails之类的MVC框架).

Ideally, generating emails resides in the business logic and should thusly be contained within a model (assuming you're using an MVC framework like rails).
