ActionController :: RoutingError:未初始化的常量MicropostsController

Question

更新:这是由于拼写错误的文件名

正确:
~/sample_app/app/controllers/microposts_controller.rb

不正确的:
~/sample_app/app/controllers/microposts_contoller.rb

在完成第10.3章的过程中,我陷入困境.最后,一个拼写错误的文件名让我追了几天幽灵.

Answer 1

这是由于拼写错误的文件名〜/ sample_app/app/controllers/microposts_controller.rb(是microposts_contoller.rb)

Answer 2

如果您有映射嵌套目录的嵌套路由，也可能会发生这种情况：

Started POST "/brokers/properties/5/images/upload" for ...

ActionController::RoutingError (uninitialized constant Brokers::ImagesController):

namespace :brokers do
  resources :properties, only: [] do
    collection do
      post 'upload'
    end
    member do
      resources :images, only: [] do
        collection do
          post 'upload'
        end
      end
    end
  end
end

images_controller.rb您必须按以下结构放置文件：

-controllers
 |-brokers
   |-images_controller.rb

注意目录结构中images_controller.rb是经纪人的直系后代。

因此，为了让 Rails 找到您的类，不要properties在brokers映射路由结构中创建子目录，它必须是代理的直接后代
