Question

我有一个旧的rails项目，我需要对其进行更改，甚至可能更新。

我的宝石列表如下所示：

当我运行rake test时，我得到：

/Users/noah/.rvm/gems/ruby-1.8.7-p371@website/gems/activesupport-2.3.14/lib/active_support/dependencies.rb:469:in `load_missing_constant': uninitialized constant AuthenticatedTestHelper (NameError)

Errors running test:units and test:functionals!

这是我的测试助手的第一部分：

ENV["RAILS_ENV"] = "test"
require File.expand_path(File.dirname(__FILE__) + "/../config/environment")
require 'test_help'
include AuthenticatedTestHelper

包含include AuthenticatedTestHelper的任何地方都失败了。关于为什么会这样做的任何想法？

更新

我认为我的问题是restful_authentication无法生成提供AuthenticatedTestHelper的文件。

在依赖关系中，我有以下内容：

qualified_name = qualified_name_for from_mod, const_name
      path_suffix = qualified_name.underscore
      name_error = NameError.new("uninitialized constant #{qualified_name}")

      file_path = search_for_file(path_suffix)
      if file_path && ! loaded.include?(File.expand_path(file_path)) # We found a matching file to load
        require_or_load file_path
        raise LoadError, "Expected #{file_path} to define #{qualified_name}" unless uninherited_const_defined?(from_mod, const_name)
        return from_mod.const_get(const_name)
      elsif mod = autoload_module!(from_mod, const_name, qualified_name, path_suffix)
        return mod
      elsif (parent = from_mod.parent) && parent != from_mod &&
            ! from_mod.parents.any? { |p| uninherited_const_defined?(p, const_name) }
        # If our parents do not have a constant named +const_name+ then we are free
        # to attempt to load upwards. If they do have such a constant, then this
        # const_missing must be due to from_mod::const_name, which should not
        # return constants from from_mod's parents.
        begin
          return parent.const_missing(const_name)
        rescue NameError => e
          raise unless e.missing_name? qualified_name_for(parent, const_name)
          raise name_error
        end
      else
        puts file_path #added this line
        raise name_error
      end
    end

我添加了行put file_path，这是nil，所以rails再也不知道这个文件在哪里。有什么想法吗？

通常这个模块应该在lib/authenticated_test_helper.rb

如果您无法找到它或在别处找到它，您只需在该文件中创建一个空模块，然后逐步实现或存根。

但是，如果您计划升级到Rails 3，则必须选择另一个身份验证框架（Authlogic，Devise），因为restful_authentication似乎不适用于Rails 3。

PS：来自dependencies.rb的代码对您没有帮助。它只包含从常量（在您的情况下为模块）中派生文件名的代码它只是失败，因为您的加载路径中没有名为authenticated_test_helper的文件。

`load_missing_constant＆＃39;：未初始化的常量AuthenticatedTestHelper（NameError）
