ReportsController＃show中的NameError未初始化的常量Report Rails.root：/ vagrant

Question

我目前正在尝试获取当前页面，以使用rails show.html.haml渲染模板，但出现此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

我不确切知道我在做什么错，但是我认为这与路线有关，或者我没有创建Rails期望的东西。 我收到一个未初始化的常量报告。 我认为我需要定义资源，但是似乎没有用，所以我可能没有正确执行，因此在下面的路由文件中将其排除。 任何帮助将不胜感激

这是我的路线文件

# Route prefixes use a single letter to allow for vanity urls of two or more characters
Rails.application.routes.draw do
  if defined? Sidekiq
    require 'sidekiq/web'
    authenticate :user, lambda {|u| u.is_admin? } do
      mount Sidekiq::Web, at: '/admin/sidekiq/jobs', as: :sidekiq
    end
  end

  mount RailsAdmin::Engine => '/admin', :as => 'rails_admin' if defined? RailsAdmin

  # Static pages
  match '/error' => 'pages#error', via: [:get, :post], as: 'error_page'
  get '/terms' => 'pages#terms', as: 'terms'
  get '/privacy' => 'pages#privacy', as: 'privacy'

  get '/reports' => 'reports#show'

  # Dummy preview pages for testing.
  get '/p/test' => 'pages#test', as: 'test'
  get '/p/email' => 'pages#email' if ENV['ALLOW_EMAIL_PREVIEW'].present?

  get 'robots.:format' => 'robots#index'

  root 'pages#home'

Answer 1

class ReportsController < ApplicationController
  load_and_authorize_resource

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

本来应该

class ReportsController < ApplicationController
  load_and_authorize_resource :user

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