我一直在努力理解为什么我无法获取为我的 Rails 项目创建的视图文件。文档显示生成控制器也会生成关联视图： Rails Docs
如果我使用相同的命令，我会生成一个文件，即控制器。 My command
我的 Rails 项目中 Views 文件夹中仅有的两个文件是 mailer.html.erb 和 mailer.text.erb
我做错了吗？我是否手动创建视图文件，如果是这样，我似乎无法将它们“连接”到关联的控制器。我是 Rails 的新手，所以任何见解都会有所帮助。谢谢！

标签： ruby-on-rails view controller
试试这个命令：
rails g controller Articles index create
如果您在命令中输入控制器名称，您可以动态创建方法和视图。
【讨论】：
您只在命令中创建了一个控制器，而不是任何方法，这就是不生成视图的原因。如果您需要为特定方法生成视图，则可以运行下面列出的命令。
rails g控制器文章索引展示
这里，index、show 是方法名。因此，此命令将创建 ArticlesController 以及相应的视图文件。
【讨论】：
您可以使用scaffold 选项。
rails g scaffold Post name:string title:string content:text
此命令将生成以下文件。
