哈特尔教程中的下一个新手问题。现在在第7章。当我运行应用程序时,我的浏览器中会出现如下内容:

ActiveRecord::RecordNotFound in UsersController#show

Couldn't find User with id=1

Rails.root: C:/rails_project/my_app
Application Trace | Framework Trace | Full Trace

我的用户_controller.rb如下所示:

   class UsersController < ApplicationController

     def show
    @user = User.find(params[:id])
    describe "profile page" do  
    #Code to make a user variable
    before { visit user_path(user) }

        it { should have_selector('h1',    :text => user.name) }
        it { should have_selector('title', :text => user.name) }
    end
  end


  def new
  end


  end
class UsersControlleruser.name)}
它{应该有_选择器('title',:text=>user.name)}
结束
结束
def新
结束
结束

谢谢你的帮助和关心

您可以使用
find\u by\u id
而不是
find

find
在模型中不存在参数时会导致错误

您确定数据库中有用户吗?请叫我lame,但我如何检查它?试试这个:看看您的sqlite数据库中有什么可能我遗漏了什么,但您是否将测试代码与控制器代码放在一起了?我一直理解测试代码放在一个单独的文件中。你检查过你是否有用户了吗?另一种方法是进入命令行,键入
rails c--sandbox
,后跟
User.find(1)
