ruby-on-rails - ActionController::RoutingError: 未初始化的常量 MicropostsController

Question

更新：这是由于文件名拼写错误

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

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

在完成第10.3章时，我被卡住了。最后，一个拼写错误的文件名让我追了几天鬼。

$ rspec spec/requests/authentication_pages_spec.rb

Answer 1

这是由于文件名拼写错误 ~/sample_app/app/controllers/microposts_controller.rb（原为 microposts_contoller.rb）

Answer 2

如果您有一个映射嵌套目录的嵌套路由，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images_controller.rb使用以下结构放置文件：

-controllers
 |-brokers
   |-images_controller.rb

注意目录结构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

如果有人遇到类似问题，只是为了帮助：

我拼错了控制器，如果您在 products 中键入没有 s是错误的：

错误的：

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

对：

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

Answer 4

在routes.rb我输入resource而不是resources

Answer 5

在我的路线中：我有“/”而不是所有“get”的“#”，所以将其更改为“#”get 'all' => 'storefront#all_items'

得到“分类”=>“店面#items_by_category”

获得“品牌”=>“店面#items_by_brand”

这解决了我所有的错误。

Answer 6

我错误地将以下内容包含在我的application_controller.rb

正确的： 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
