我完成了这本书.我在每一步后运行"rspec spec /".
第11章未能在列表11.27中添加app/views/pages/home.html.erb在列表11.30之后失败.将微博实例变量添加到主动作.应用程序/控制器/ pages_controller.rb
一切都应该是有效的.事实并非如此.我刚刚第一次进入轨道.既然这是剪切和粘贴代码,我没想到错误.
我将非常感谢任何帮助调试这个.如果我剪切和粘贴错误,或者如果Michel的代码示例没有经过全面测试,请将其删除.
这是rspec输出:

完成2.04秒103例,4次失败MPECHNER-MBP:sample_app michael.pechner $
我搜索了git hub以寻找其他已经完成此任务的人.我发现它在https://github.com/mfmcgran的帖子中 "app/views/shared/_error_messages.html.erb"似乎是错的,我把第一行的代码显示为"if @ users.errors.任何？" 广告它需要"如果object.errors.any？" 第11章没有提到这需要改变.但是在这次改变之后,所有103次rpsec测试都通过了.
