更新：这是由于拼写错误的文件名

造成的

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

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

这是我在这里的第一个贡献，赞赏有关改进这个或未来帖子的反馈意见：）

在完成章节10.3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。

$ rspec spec/requests/authentication_pages_spec.rb
No DRb server is running. Running in local process instead ...

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

如果您有嵌套路径映射嵌套目录，也会发生这种情况：

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

您必须将images_controller.rb文件放在以下结构中：

-controllers
 |-brokers
   |-images_controller.rb

注意目录结构中images_controller.rb是代理的直接后代。

因此，为了让Rails找到你的类，不要在映射路由结构的properties内创建一个子目录brokers，它必须是经纪人的直接后代

Answer 3

在routes.rb我输入resource而不是resources

Answer 4

如果有人遇到类似问题，请提供帮助：

我拼错了控制器，如果你在没有 s in products 的情况下输入它就错了：

错：

forEach()

右：

get '/my_products', to: 'product#my_products'

Answer 5

在我的路线中：我有＃34; /＆＃34;而不是＆＃34;＃＆＃34;对于所有＆＃34; get＆＃34;，所以将其更改为＆＃34;＃＆＃34; 得到所有＆＃39; =＆GT; ＆＃39;＃店面all_items＆＃39;

得到＆＃39;分类＆＃39; =＆GT; ＆＃39;＃店面items_by_category＆＃39;

获得品牌推广＆＃39; =＆GT; ＆＃39;＃店面items_by_brand＆＃39;

修复了我的所有错误。

Answer 6

我在application_controller.rb

中错误地包含了以下内容

正确： include ActionController::MimeResponds

不正确： include ActionController::MimeResponse

# /controllers/api/v1/application_controller.rb

module Api
  module V1
    class ApplicationController < ActionController::API
      include ActionController::MimeResponds
    end
  end
end
