Question

我正在尝试通过railstutorial.org上的Rails教程来解决这个问题。我在测试中的user_path应该转到单个用户的个人资料页面，而是转到用户/索引（我还没有创建它）。

/ *我的测试代码* /

  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

/ *失败：* /

routes文件显示user_path应该给我user / {id}左右

/ * 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

Answer 1

在调用访问user_path（@user）

之前，您应首先使用 @ user.save！保存用户

因为在您保存用户之前，它不会持久存储在数据库中，也不会有任何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

Answer 2

您是否检查过@user是否有值？

user_path(@user)将转到/users/<@user.id>，但如果@user为nil，则会尝试/users/。鉴于您还没有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 - 将.new更改为.create或添加@user.save。其次，您的params[:id]未在测试代码中填充，因此查找失败（将controller.params[:id] = @user.id添加到您的测试中）。（第三，在上一次测试中你有一个拼写错误shoult而不是should。）

Answer 3

您似乎没有包含测试代码，这对解决此问题非常有帮助。最有可能的是，你在测试中将@user设置为nil，修复它将解决问题。

将user_path路由到用户/索引而不是用户/ id
