ReportsController 中的 NameError#show uninitialized constant Report Rails.root: /vagrant

Question

我目前正在尝试让我的当前页面呈现一个带有 rails show.html.haml 的模板，但是我得到了这个未初始化的常量错误。我生成了控制器，但是我没有生成脚手架，因为我不想使用模型来生成页面。下面是错误

NameError in ReportsController#show uninitialized constant Report  Rails.root: /vagrant

我不确切知道我做错了什么，但我认为这与路线有关，或者我没有创建 rails 期望的东西。我收到一份未初始化的常量报告。我想我需要定义资源，但似乎没有用，所以我可能没有正确完成，所以它被排除在我下面的路由文件中。任何帮助将不胜感激

这是我的路线文件

class ReportsController < ApplicationController
  load_and_authorize_resource

  def show
    render template: "reports/show"
  end
end

%h1
  hello world!

Answer 1

class ReportsController < ApplicationController
  load_and_authorize_resource

  def show
    render template: "reports/show"
  end
end

应该是

class ReportsController < ApplicationController
  load_and_authorize_resource :user

  def show
    render template: "reports/show"
  end
end
