Ruby on rails Rails教程无法找到字段“0”；名称“；在10.34之后按规格运行

我正在学习Rails教程，我遇到了一个问题，它似乎导致许多其他测试失败。共有23个错误，其中大多数错误说明缺少名为“Name”的字段。当我运行命令时

bundle exec rspec spec/requests/user_pages_spec.rb

我发现以下错误（每次运行时似乎都会改变顺序）：

1） 使用有效信息编辑用户页面 失败/错误：在“名称”中填入：新名称 Capybara:：ElementNotFound: 找不到字段“Name” #./spec/requests/user\u pages\u spec.rb:136:in'block（4级）in'

结果，许多其他案例似乎都失败了。什么应用程序文件会导致此问题？sessions\u helper.rb

这是我的规范/请求/用户页面\u spec.rb：需要“规范助手”

运行规范时收到的错误表明

Capybara

需要填写一个名为

“Name”

的字段（因为您要求它在

行的“Name”中填写：new\u Name

）

如果由于某种原因，登录后您无法访问用户表单，或者用户表单缺少

“Name”

字段，这将解释您的失败

在你的简历中，你说你在注册后没有收到任何表格，所以这肯定可以解释这一点

要验证这一点，您可以向

描述“页面”

添加测试，如下所示：

it { should have_field("Name") }

如果失败-您不能期望任何依赖于该字段的测试通过…

您的HTML表单是什么样子的？是否有一个名称字段？投票决定关闭，但我还没有通读，看它是否是一个合理陈述的问题。它太长了，无法阅读。您的视图中有“名称”字段吗？谢谢大家的快速回复。我知道这是个蹩脚的模糊问题，我不知道该怎么问。当我单击登录时，电子邮件和密码字段都在那里。然而，当我点击注册时，那里根本没有任何表单！我将回顾代码，但有人能建议这样的错误是否会导致表单不显示或visa卡不显示？我不认为这是一个糟糕的问题。当你是初学者时，很难知道哪个代码对问题很重要。
