我正在关注 ruby​​.railstutorial.org，对我的应用程序进行了一些细微的修改。我正在尝试运行关系控制器规范，但我不断收到以下错误：

$ bundle exec rspec spec/controllers/relationships_controller_spec.rb
Exception encountered: #<NameError: uninitialized constant RelationshipsController>

我刚刚发现，如果我在 spork 未运行时尝试测试，则测试通过，但如果 spork 正在运行，我会收到上述错误。

这是我的 spec_helper.rb 文件：

    require 'rubygems'
require 'spork'

Spork.prefork do
  # Loading more in this block will cause your tests to run faster. However, 
  # if you change any configuration or code from libraries loaded here, you'll
  # need to restart spork for it take effect.
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'

  # Requires supporting files with custom matchers and macros, etc,
  # in ./support/ and its subdirectories.
  Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

  RSpec.configure do |config|
    # == Mock Framework
    #
    # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
    #
    # config.mock_with :mocha
    # config.mock_with :flexmock
    # config.mock_with :rr
    config.mock_with :rspec

    config.fixture_path = "#{::Rails.root}/spec/fixtures"

    # If you're not using ActiveRecord, or you'd prefer not to run each of your
    # examples within a transaction, comment the following line or assign false
    # instead of true.
    config.use_transactional_fixtures = true

    def test_sign_in(user)
      controller.sign_in(user)
    end
  end
end

Spork.each_run do
end

这是我的 Relations_controller.rb 文件：

    class RelationshipsController < ApplicationController
  before_filter :authenticate

  def create
    @user = User.find(params[:relationship][:followed_id])
    current_user.follow!(@user)
    redirect_to @user
    end
  end

  def destroy
    @user = Relationship.find(params[:id]).followed
    current_user.unfollow!(@user)
    redirect_to @user
    end
  end
end

这是我的 Relations_controller_spec.rb 文件：

    require 'spec_helper'

describe RelationshipsController do

  describe "access control" do

    it "should require signin for create" do
      post :create
      response.should redirect_to(signin_path)
    end

    it "should require signin for destroy" do
      delete :destroy, :id => 1
      response.should redirect_to(signin_path)
    end
  end

  describe "POST 'create'" do

    before(:each) do
      @user = test_sign_in(Factory(:user))
      @followed = Factory(:user, :email => Factory.next(:email))
    end

    it "should create a relationship" do
      lambda do
        post :create, :relationship => { :followed_id => @followed }
        response.should be_redirect
      end.should change(Relationship, :count).by(1)
    end
  end

  describe "DELETE 'destroy'" do

    before(:each) do
      @user = test_sign_in(Factory(:user))
      @followed = Factory(:user, :email => Factory.next(:email))
      @user.follow!(@followed)
      @relationship = @user.relationships.find_by_followed_id(@followed)
    end

    it "should destroy a relationship" do
      lambda do
        delete :destroy, :id => @relationship
        response.should be_redirect
      end.should change(Relationship, :count).by(-1)
    end
  end
end

我还添加了“关注”和“取消关注”按钮来创建和删除关系。如上所述，如果 spork 未运行，则关系控制器规范 rb 将通过。但是，当我单击浏览器中的后续按钮时，浏览器给了我相同的“未初始化的常量关系控制器”错误。

我的测试在没有 spork 的情况下运行良好，但由于 spork 出现错误而失败，我遇到了同样的问题：

NameError: uninitialized constant.....

问题是我的模型中的一个类的文件名与模型名称不完全匹配。您确定您的用户类和关系类分别命名为 user.rb 和 relationship.rb 吗？
