我正在研究 Hartl 的 Rails 教程，第 9.2.1 节结束。我的测试没有通过。想不通为什么。希望有人可以提供帮助。我附上了错误消息和两个相关文件 1) authentication_pages_spec.rb 和 2) users_controller.rb 下面

失败：

1）访问编辑页面的用户控制器中未登录用户的身份验证授权失败/错误：它{应该有_title（'登录'）}预期#has_title？（“登录”）返回真，得到假# ./spec/requests/authentication_pages_spec.rb:57:in `block (6 levels) in '

2）用户控制器中的未登录用户的身份验证授权提交更新操作失败/错误：在 { patch user_path(user) } ActionController::ParameterMissing: param not found: user # ./app/controllers/users_controller 之前.rb:40:in user_params' # ./app/controllers/users_controller.rb:27:inupdate' # ./spec/requests/authentication_pages_spec.rb:61:in `block (6 levels) in '

在 2.08 秒内完成 60 个示例，2 次失败

失败的例子：

rspec ./spec/requests/authentication_pages_spec.rb:57 # 访问编辑页面的用户控制器中未登录用户的身份验证授权 rspec ./spec/requests/authentication_pages_spec.rb:62 # 未签名的身份验证授权-在用户控制器中的用户中提交更新操作

我的 authentication_pages_spec.rb 是

require 'spec_helper'

describe "Authentication" do

subject { page }


describe "signin page" do
    before { visit signin_path }

    it { should have_content('Sign in') }
    it { should have_title('Sign in') }
  end


describe "signin" do
      before { visit signin_path }

      describe "with invalid information" do
            before { click_button "Sign in" }

            it { should have_title('Sign in') }
            it { should have_selector('div.alert.alert-error', text: 'Invalid') }

            describe "after visiting another page" do
              before { click_link "Home" }
              it { should_not have_selector('div.alert.alert-error') }
            end
          end

    describe "with valid information" do
      let(:user) { FactoryGirl.create(:user) }
      before { sign_in user }

      it { should have_title(user.name) }
      it { should have_link('Profile',     href: user_path(user)) }
      it { should have_link('Settings',    href: edit_user_path(user)) }
      it { should have_link('Sign out',    href: signout_path) }
      it { should_not have_link('Sign in', href: signin_path) }


     describe "followed by signout" do
       before { click_link "Sign out" }
         it { should have_link('Sign in') }
       end
     end
  end

  describe "authorization" do
    describe "for non-signed-in users" do
      let(:user) { FactoryGirl.create(:user) }

      describe "in the Users controller" do

        describe "visiting the edit page" do
          before { visit edit_user_path(user) }
          it { should have_title('Sign in') }
        end

        describe "submitting to the update action" do
          before { patch user_path(user) }
          specify { expect(response).to redirect_to(signin_path) }
        end
      end
    end
  end        
end

users_controller.rb 是

 class UsersController < ApplicationController

 def show
@user = User.find(params[:id])
 end

 def new
@user = User.new
 end

 def create
  @user = User.new(user_params)
  if @user.save
    flash[:success] = "Welcome to the Sample App!"
    redirect_to @user
  else
    render 'new'
  end
end

def edit
    @user = User.find(params[:id])
  end

def update
  @user = User.find(params[:id])
  if @user.update_attributes(user_params)
    flash[:success] = "Profile updated"
    sign_in @user
    redirect_to @user      
  else
    render 'edit'
  end
end


private

  def user_params
    params.require(:user).permit(:name, :email, :password,
                                 :password_confirmation)
  end

  # Before filters

  def signed_in_user
    redirect_to signin_url, notice: "Please sign in." unless signed_in?
  end       
end

您在 users_controller.rb 的第 2 行缺少对您的 signed_in_user 过滤器的调用。您在控制器末尾定义了过滤器，但您没有调用它！:)

在本教程的最后，该行应如下所示：

before_action :signed_in_user, only: [:index, :edit, :update, :destroy, :following, :followers]

但是，由于您还没有创建追随者，我认为它应该看起来像这样：

before_action :signed_in_user, only: [:index, :edit, :update, :destroy]

我发现将代码的最终源复制到我的硬盘驱动器上非常有用，因此每当我在编写本书时遇到错误时，我都可以将我的代码与原始代码进行比较。
