我陷入了一个非常奇怪的问题。我最近从 rails 4.1 更新到 4.2。在 4.1 中一切正常。但是现在，在 4.2 中，模型关注内容似乎被忽略了，即使找到了关注点。

说得简单。我有一个Client模型，它属于在关注点Address中定义的Addressable关系：

应用程序/模型/client.rb

class Client < ActiveRecord::Base
  include Addressable
end

应用程序/模型/地址.rb

class Address < ActiveRecord::Base
end

应用程序/模型/关注/addressable.rb

module Addressable
  extend ActiveSupport::Concern

  included do
    belongs_to :address
  end

环境没有问题development。我可以Client.new.address毫无问题地做。但是在test环境中，同一行给了我一个unknow method address错误。如果我搬到belongs_to :address那里Client，它会再次起作用。该模块被包含在内，因为这没有错误，如果我将名称更改为Adressabledewdewdedthen，当然会出现错误。

验证方法等也会发生同样的情况。

我一直在调试这个，但我没有找到根。我已经复制了我development.rb的 astest.rb并重新启动了服务器，但仍然如此。我无法在全新的 Rails 4.2 应用程序中重现这一点，因此它与我的应用程序或更新过程有关，但不知道在哪里。

有人有线索吗？

谢谢

Client.new.address这是在测试环境中的控制台中执行的堆栈跟踪（在开发中它有效）：

两种环境中的结果Client.ancestors是（当然，没有实例身份的唯一区别）：

并且做Client.reflections.keys使出address现在开发中而不是在测试中。

我知道了。问题是仅存在于我的测试环境（json-schema）中的addressablegem，在其依赖项之间具有 gem，即定义Addressable模块。因此，当 Rails 尝试自动加载时Addressable，它会找到定义的类addressable而不是我的关注类。所以，当然，该模块被包括在内，但它不是我想的那个。

更新我的 Gemfile时，自 2014 年 11 月以来json-schema已更新并且现在依赖于。addresable

很难抓住这个:)
