I am trying to work through the Rails tutorial at railstutorial.org and am stuck at this problem. My user_path in the test is supposed to go to the individual user's profile page, but is instead going to users/index (which I haven't created yet, on purpose).

/* My test code */

  describe "profile page" do
    #let(user) { FactoryGirl.create(:user) }
    @user = User.new(name: "Example User", email: "user@example.com",
                    password: "foobar", password_confirmation: "foobar")
    before { visit user_path(@user) }

    it { should have_content(user.name) }
    it { shoult have_title(user.name)   }

  end

/* Failures: */

The routes file shows that user_path should give me users/{id} or so

/* users_controller.rb*/

class UsersController < ApplicationController

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

    def new
    end

end

/* config/routes.rb */

SampleApp::Application.routes.draw do

  resources :users
  root 'static_pages#home'

  match '/signup',  to: 'users#new',            via: 'get'
  match '/help',    to: 'static_pages#help',    via: 'get'
  match '/about',   to: 'static_pages#about',   via: 'get'
  match '/contact', to: 'static_pages#contact', via: 'get'

end

您应该先使用@user.save 保存用户！在调用之前访问 user_path(@user)

因为在您保存用户之前，它不会保留在数据库中并且不会有任何 id。

describe "profile page" do
  #let(user) { FactoryGirl.create(:user) }
  @user = User.new(name: "Example User", email: "user@example.com",
                password: "foobar", password_confirmation: "foobar")

 # Add this to your code ..
  @user.save! 

  before { visit user_path(@user) }

  it { should have_content(user.name) }
  it { shoult have_title(user.name)   }

end

你检查过是否@user有价值吗？

user_path(@user)会去，/users/<@user.id>但如果@user 为零，它会尝试去/users/。鉴于您尚未创建索引方法和视图，这可能就是它失败的原因。

感谢您的测试代码。首先，您的用户不在数据库中 - 更改.new为.create或添加@user.save. 其次，您params[:id]没有在测试代码中填充，因此查找将失败（添加controller.params[:id] = @user.id到您的测试中）。（第三，你有一个错字shoult，而不是should在最后一次测试中。）

您似乎没有包含您的测试代码，这对解决这个问题非常有帮助。最有可能的是，您在测试中将 @user 设置为 nil，修复它可以解决问题。
