在Rails加载完成后运行代码？

问题描述

我有一个定期任务，需要每分钟执行一次（使用delay_job）。我希望Rails可以在完成加载后立即自动将其排队，如果系统中还没有这样的任务。

哪里是个好地方让我在整个Rails引导流程结束时运行一些代码？有人建议config / environments / development.rb（或其他环境），但是当我从那里排队作业时，delay_job给了我ActiveRecord问题。

我咨询了，而且似乎没有明确的位置

这种部署后设置是否可能是在我的应用程序代码的外部完成的，也许是通过rake或其他方式完成的？有什么建议吗？

谢谢！

解决方案

关于，抱歉，我们正在努力重写它。对于您的问题，我会尝试在您的应用程序中使用 config.after_initialize 。rb

  def after_initialize（& block）
 ActiveSupport.on_load（：after_initialize，：yield => true，& block）
 end 
   
I have a periodic task that needs to execute once a minute (using delayed_job). I would like for Rails to automatically queue it up as soon as it's finished loading, if one such task isn't already present in the system.

What is a good place for me to run some code right at the end of the entire Rails boot flow? Someone suggested config/environments/development.rb (or other environment), but delayed_job give me ActiveRecord issues when I queue up jobs from there.

I consulted http://guides.rubyonrails.org/initialization.html, and there doesn't seem to be a clear location for that kind of code either.

Is this kind of post-deployment setup to be done perhaps externally to my app's code, maybe through rake or some other means? Any suggestions?

Thank you!

Regarding http://guides.rubyonrails.org/initialization.html, sorry, we're working hard to rewrite it. For your problem, I would try with config.after_initialize in your application.rb
def after_initialize(&block)
  ActiveSupport.on_load(:after_initialize, :yield => true, &block)
end
