未初始化的常量控制器

Question

我的路线有问题......

routes.rb

resources :documents do

  resources :user do
     delete 'user_unassign'
  end

  resources :attachments do    
    collection do
      get :index_parent_attachments
    end
  end

end

resources :document_types do
   resources :documents
end



devise_scope :user do
     #    root :to => "devise/sessions#new" #, :as => :root
 end

       devise_for :users 

 namespace :admin do
   resources :users, :document_types
 end

当我点击此链接时：

<%= link_to 'unfollow', document_user_user_unassign_path(document, user.id), :method => 'delete' %>

它遵循这条路由localhost：3000 / documents / 1 / user / 2 / user_unassign我得到一个错误：uninitialized constant UserController

路线

Answer 1

将 resources :user 更改为 resources :users

更新

将routes.rb文件更改为

#routes.rb
resources :documents do

  resources :users do
     member do
       delete 'user_unassign'
     end
  end

end

然后在你的视图中

<%= link_to 'unfollow', user_unassign_document_user_path, :method => 'delete' %>

注意 user_unassign_document_user_path 会为您提供类似localhost:3000/documents/:document_id/users/:id/user_unassign(.:format)

的路线

Answer 2

更新您的resources :documents路线，如下所示：

resources :documents do

  namespace :admin do       ## Added namespace
    resources :users do     ## updated resources as users(plural)
      delete 'user_unassign'
    end
  end                       ## end of :admin namespace 

  resources :attachments do    
    collection do
      get :index_parent_attachments
    end
  end

end
