这真的很奇怪。我只是输入了

rails new website

使用以下命令创建控制器:

rails generate controller static home about index

当我去localhost:3000/static/home时,我收到错误:

NoMethodError in StaticController#about

这是终端

中的错误日志

我在rake路线下得到这个

            Prefix Verb URI Pattern                   Controller#Action
       static_home GET  /static/home(.:format)        static#home
      static_about GET  /static/about(.:format)       static#about
      static_class GET  /static/class(.:format)       static#class
    static_contact GET  /static/contact(.:format)     static#contact
      static_index GET  /static/index(.:format)       static#index
static_instructors GET  /static/instructors(.:format) static#instructors
static_testimonial GET  /static/testimonial(.:format) static#testimonial

此外,所有观点都已创建。通过控制器,路线和视图,我不知道为什么事情还没有工作。

控制器代码:

class StaticController < ApplicationController
  def home
  end

  def about
  end

  def class
  end

  def contact
  end

  def index
  end

  def instructors
  end

  def testimonial
  end
end

非常感谢任何帮助!
