为什么不执行 Railtie 初始化程序? [英] Why Railtie initializers are not executed?

问题描述

在制作 Passenger-Monit 插件时，我认为它最适合使用初始化器，即

<预><代码>乘客监控模块类 Railtie <Rails::Railtie初始化程序my_plugin.some_init_task"做# 我的初始化任务结尾结尾结尾

然而，由于某种原因，块中的代码从未执行过.我终于解决了

config.before_initialize {}

但我很好奇，为什么不执行初始化程序.什么可能阻止它运行?

解决方案

在您的 gemfile 中，您是否添加了

gem "Passenger-Monit"

否则你需要把它放在你的加载路径中并在你的应用程序中要求它.http://www.igvita.com/2010/08/04/rails-3-internals-railtie-creating-plugins/

祝你好运！

While crafting the Passenger-Monit plugin, I thought that it'll be most appropriate to use the initializer, i.e.

module PassengerMonit
  class Railtie < Rails::Railtie
    initializer "my_plugin.some_init_task" do
      # my initialization tasks
    end
  end
end

However, for some reason the code in the block was never executed. I finally made a work-around with

config.before_initialize {}

but I'm curious, why the initializer wasn't executed. What could have prevented it from running?

解决方案

In your gemfile, did you add

gem "Passenger-Monit"

Otherwise you need to put it in your load path and require it in your application. http://www.igvita.com/2010/08/04/rails-3-internals-railtie-creating-plugins/

Good luck!
