Rails未初始化的常量RelationshipController（NameError）

Question

我跟随ruby.railstutorial.org对我的应用程序进行了一些细微的修改。我试图运行relationships_controller_spec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>

我发现，如果我尝试测试，同时叉勺未运行，那么测试通过，但如果叉勺运行，我得到上面的错误。

这里是我的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 

这里是我的relationships_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 

，这里是我的relationships_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，则会传递relationships_controller_spec.rb。但是，当我点击浏览器中的后续按钮时，浏览器会给我提供相同的“未初始化的常量RelationshipsController”错误。

我有同样的问题，我的测试运行良好的W/O叉勺，但与叉勺未能给出错误：

NameError: uninitialized constant.....

的问题是在我的模型中的一个类的文件名没有不完全符合型号名称。你确定你的User类和Relationship类分别命名为user.rb和relationship.rb吗？
