Question

当我运行我的Rails应用程序时，我收到以下错误，＆＃34;未初始化的常量Blog :: PostsController＆＃34;

的routes.rb

Rails.application.routes.draw do

  devise_for :authors
  root to: 'blog/posts#index'

  namespace :author do
    resources :posts
  end

  scope module: 'blog' do
    get 'about'     => 'pages#about',   as: :about
    get 'contact'   => 'pages#contact', as: :contact
    get 'posts'     => 'posts#index',   as: :posts   
    get 'posts/:id' => 'posts#show',    as: :post
  end

end

posts.controller.rb

module Blog
  class PostsController < BlogController   

    def index
      @post = Post.most_recent
    end

    def show
      @post = Post.friendly.find(params[:id])
    end

  private

    def set_post

    end

  end    
end

目录路径如下：

app/controller/blog/posts.controller.rb

我猜问题是在命名约定中。以下是命名约定的示例：

Controller Naming Convention

Class: PostsController

File: /app/controllers/posts_controller.rb

有关命名惯例的更多详细信息，请查看：http://www.ganeshkunwar.com.np/2018/01/02/naming-convention-rails/

还从application_controller继承post控制器，而不是从blog控制器继承。

未初始化的常量Blog :: PostsController
