仅在服务器模式下向 Rails 3 启动过程添加初始化步骤
根据 http://edgeapi.rubyonrails.org/classes/Rails/Railtie.html，如果我编写一个 Rails 3 插件并且想要挂钩初始化过程，我会写
class MyRailtie < Rails::Railtie
initializer "my_railtie.configure_rails_initialization" do
# some initialization behavior
end
end
但是，这个初始化程序似乎是在您运行时执行的，例如，Rails rake 任务，而不是就在您运行 rails s 或类似命令时。我的问题是，如何防止此块中的代码在 Rails 任务期间运行，而不是在完整的 Rails 服务器启动期间运行？这似乎是 Rails 3 插件的常见问题。
According to http://edgeapi.rubyonrails.org/classes/Rails/Railtie.html, if I write a Rails 3 plugin and I want to hook into the initialization process, I write
class MyRailtie < Rails::Railtie
initializer "my_railtie.configure_rails_initialization" do
# some initialization behavior
end
end
However, this initializer appears to be executed when you run, for instance, a Rails rake task, not just when you run rails s or similar. My question is, how do I prevent my code in this block from being run during Rails tasks, as opposed to full Rails server boot-ups? This seems to be a common problem with Rails 3 plugins.

将此块添加到您的初始化程序中：
这应该适用于当前的 3.0.6 Rails 版本。
add this block to your initializer:
this should work with the current 3.0.6 rails version.
早在我发布这个问题时，Mongoid 就遇到了这个问题。我在此处报告了该问题，并通过将代码包装在
config 中解决了这个问题.after_initialize块。如果 Rails 未初始化，则永远不会调用此块。更多信息请参见此处。Way back when I posted this question, Mongoid was experiencing this issue. I reported it here, and it was resolved by wrapping the code in a
config.after_initializeblock. If Rails isn't initialized, then this block is never called. More information here.
