请检查并通知我。成功保存后，您的
创建显示routes.rbShowShow你能试着运行这个命令吗？这将列出rails应用程序的所有有效路由。您只需使用资源：路由文件中的设置和rails RESTFUL路由将处理所有问题。您不需要显式地声明restful路由的HTTP谓词。
另外，在控制器的创建和更新操作中，使用@setting而不是@setting。您是否使用了“rails生成脚手架设置”命令？@ajt是的，我使用了该命令。@SrikanthVenugopalan我已编辑了该问题，请检查并告知我。请检查并告知我know@PeeVee，我正在调查，我怀疑某个地方有一个打字错误（可能是复数），我想猜猜是哪里。如果我有代码可以使用，可能会更容易。首先猜测-在您的创建中，if块具有
@设置。使用大写字母“S”保存。您能否尝试保存@设置
？在哪一行出现错误？我怀疑@设置
会给您带来问题。堆栈跟踪可能更好。
