ruby-on-rails-4 - hartl 教程在 9.2.1 结束时未通过测试

Question

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。不知道为什么。希望有人能提供帮助。我已在下面附上错误消息和两个相关文件 1) authentication_pages_spec.rb 和 2) users_controller.rb

失败:

1) 访问编辑页面的Users Controller 中对未登录用户的鉴权授权 失败/错误:它 { should have_title('Sign in') } 预期 #has_title?("Sign in") 返回 true，结果为 false # ./spec/requests/authentication_pages_spec.rb:57:in `block (6 levels) in '

2) 提交更新 Action 的Users Controller 中对未登录用户的鉴权授权 失败/错误:在 { patch user_path(user) } 之前 Action Controller ::参数缺失: 未找到参数:用户 # ./app/controllers/users_controller.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 个例子，2 个失败

失败的例子:

rspec ./spec/requests/authentication_pages_spec.rb:57 # 访问编辑页面的Users Controller 中非登录用户的认证授权rspec ./spec/requests/authentication_pages_spec.rb:62 # 提交更新操作的用户 Controller 中非登录用户的身份验证授权

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

Answer 1

您在 users_controller.rb 的第 2 行缺少对 signed_in_user 过滤器的调用。你在 Controller 的末尾定义了过滤器，但你没有调用它! :)

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关注者，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代码复制到我的硬盘上非常有用，因此我在编写本书时遇到错误时可以将我的代码与原始代码进行比较。
