在开发模式下，Rails3不会在lib中重新加载代码 [英] Rails3 not reloading code in lib while in development mode

问题描述

情况:

1. 我在lib/foo/bar.rb中有一个定义为以下简单方法的代码:

1. I have code in lib/foo/bar.rb with a simple method defined as such:

module Foo
  class Bar
    def test
      "FooBar"
    end
  end
end

在我的助手FooBarHelper中，我有:

In my helper, FooBarHelper, I have:

require `lib/foo/bar`
module FooBarHelper
  def test_foo_bar
    fb = Foo::Bar.new
    fb.test
  end
end

在我看来，我这样调用此辅助方法:

In my view, I call this helper method like so:

<%= test_foo_bar =>

在我的config/environments/development.rb中，我将目录添加到了config.autoload_paths:

In my config/environments/development.rb, I added the directory to my config.autoload_paths:

config.autoload_paths += ["#{config.root}/lib/foo"]

---

问题:

当我将Foo::Bar.test的返回值更改为例如"MODIFIED FOOBAR"时，原始返回值"FooBar"仍显示在视图上，而不是新值.

When I change the return value of Foo::Bar.test to, for example, "MODIFIED FOOBAR", the original return value, "FooBar", is still being displayed on the view and not the new value.

由于我处于开发模式，因此代码不应该在每次请求时重新加载代码吗?

Since I'm in development mode, shouldn't the code reload the code on every request?

有人可以告诉我我想念什么吗?

Could someone tell me what I'm missing?

谢谢！

推荐答案

他们在Rails 3的应用根目录中删除了lib文件夹.

They removed the lib folder the app root in Rails 3.

config.autoload_paths << 'lib'

或者您可以在助手中使用`require_dependency`.

or you can use `require_dependency` in your helper.

module FooBarHelper
  require_dependency 'foo/bar'

  def test_foo_bar
    fb = Foo::Bar.new
    fb.test
  end
end

两种方法都告诉Rails您的文件lib/foo/bar.rb应该自动加载，然后重新加载每个请求.

Both ways tell Rails that your file lib/foo/bar.rb should be autoloaded and subsequently, reloaded each request.
