Ruby on rails Rails 5：事件系统,ruby-on-rails,ruby,ruby-on-rails-5,associations,Ruby On Rails,Ruby,Ruby On Rails 5,Associations,我正在制作一个事件系统。我有一个模型事件，每个事件都有文件、报告、提供者等等 以下是我今天的路线： scope 'app', :module => "app" do resources :events, :roteiros, :convidados, :lista_convidados, :orcamentos, :orcamento_items, :providers, :provider

我正在制作一个事件系统。我有一个模型事件，每个事件都有文件、报告、提供者等等

以下是我今天的路线：

  scope 'app', :module => "app" do
    resources :events, :roteiros, 
              :convidados, :lista_convidados,
              :orcamentos, :orcamento_items, :providers, 
              :providers_items, :reports, :reports_items,
              :modelos, :modelos_items, :arquivos, :arquivos_items   
    end
我正在寻找其他模型的最佳方式，当编辑或创建新数据时，新信息与事件模型关联，然后每个事件都将有与之关联的信息

我认为应该是这样的：

scope 'app', :module => "app" do
    resources :events do

              :roteiros, 
              :convidados, :lista_convidados,
              :orcamentos, :orcamento_items, :providers, 
              :providers_items, :reports, :reports_items,
              :modelos, :modelos_items, :arquivos, :arquivos_items

    end
end
然后url看起来像
/app/events/event name/providers

我仍然需要获取事件id，以便将新记录与特定事件关联

所有模型都已具有要关联的
事件id
值

谢谢你的帮助

首先，您需要在嵌套项前面放置
资源。比如：


scope 'app', :module => "app" do
  resources :events do
    resources :roteiros, 
              :convidados, :lista_convidados,
              :orcamentos, :orcamento_items, :providers, 
              :providers_items, :reports, :reports_items,
              :modelos, :modelos_items, :arquivos, :arquivos_items
  end
end



resources :events do
  resources :arquivos, 
            :arquivos_items,
            :convidados, 
            :lista_convidados,
            :modelos, 
            :modelos_items, 
            :orcamento_items, 
            :orcamentos, 
            :providers, 
            :providers_items, 
            :reports, 
            :reports_items,
            :roteiros, 
            shallow: true
end


当您在控制台中运行
rake routes
时，它将为您提供如下信息：


    event_roteiros GET    /app/events/:event_id/roteiros(.:format)              app/roteiros#index
                   POST   /app/events/:event_id/roteiros(.:format)              app/roteiros#create
 new_event_roteiro GET    /app/events/:event_id/roteiros/new(.:format)          app/roteiros#new
edit_event_roteiro GET    /app/events/:event_id/roteiros/:id/edit(.:format)     app/roteiros#edit
     event_roteiro GET    /app/events/:event_id/roteiros/:id(.:format)          app/roteiros#show
                   PATCH  /app/events/:event_id/roteiros/:id(.:format)          app/roteiros#update
                   PUT    /app/events/:event_id/roteiros/:id(.:format)          app/roteiros#update
                   DELETE /app/events/:event_id/roteiros/:id(.:format)          app/roteiros#destroy

                   ... omitting a bunch of routes ...

            events GET    /app/events(.:format)                                 app/events#index
                   POST   /app/events(.:format)                                 app/events#create
         new_event GET    /app/events/new(.:format)                             app/events#new
        edit_event GET    /app/events/:id/edit(.:format)                        app/events#edit
             event GET    /app/events/:id(.:format)                             app/events#show
                   PATCH  /app/events/:id(.:format)                             app/events#update
                   PUT    /app/events/:id(.:format)                             app/events#update
                   DELETE /app/events/:id(.:format)                             app/events#destroy



    event_arquivos GET    /events/:event_id/arquivos(.:format)              arquivos#index
                   POST   /events/:event_id/arquivos(.:format)              arquivos#create
 new_event_arquivo GET    /events/:event_id/arquivos/new(.:format)          arquivos#new
      edit_arquivo GET    /arquivos/:id/edit(.:format)                      arquivos#edit
           arquivo GET    /arquivos/:id(.:format)                           arquivos#show
                   PATCH  /arquivos/:id(.:format)                           arquivos#update
                   PUT    /arquivos/:id(.:format)                           arquivos#update
                   DELETE /arquivos/:id(.:format)                           arquivos#destroy

                   ... omitting a bunch of routes ...

            events GET    /events(.:format)                                 events#index
                   POST   /events(.:format)                                 events#create
         new_event GET    /events/new(.:format)                             events#new
        edit_event GET    /events/:id/edit(.:format)                        events#edit
             event GET    /events/:id(.:format)                             events#show
                   PATCH  /events/:id(.:format)                             events#update
                   PUT    /events/:id(.:format)                             events#update
                   DELETE /events/:id(.:format)                             events#destroy


如您所见，这将导致所有内容都在
app
下命名。这意味着您的控制器需要如下所示：


class App::RoteirosController < ApplicationController 
  ...
end


我猜你不会想要的。因此，它应该更像：


resources :events do
  resources :roteiros, 
            :convidados, :lista_convidados,
            :orcamentos, :orcamento_items, :providers, 
            :providers_items, :reports, :reports_items,
            :modelos, :modelos_items, :arquivos, :arquivos_items
end



正如上面所讨论的，你可以考虑做一些类似的事情：


scope 'app', :module => "app" do
  resources :events do
    resources :roteiros, 
              :convidados, :lista_convidados,
              :orcamentos, :orcamento_items, :providers, 
              :providers_items, :reports, :reports_items,
              :modelos, :modelos_items, :arquivos, :arquivos_items
  end
end



resources :events do
  resources :arquivos, 
            :arquivos_items,
            :convidados, 
            :lista_convidados,
            :modelos, 
            :modelos_items, 
            :orcamento_items, 
            :orcamentos, 
            :providers, 
            :providers_items, 
            :reports, 
            :reports_items,
            :roteiros, 
            shallow: true
end


在这种情况下，您将得到如下结果：


    event_roteiros GET    /app/events/:event_id/roteiros(.:format)              app/roteiros#index
                   POST   /app/events/:event_id/roteiros(.:format)              app/roteiros#create
 new_event_roteiro GET    /app/events/:event_id/roteiros/new(.:format)          app/roteiros#new
edit_event_roteiro GET    /app/events/:event_id/roteiros/:id/edit(.:format)     app/roteiros#edit
     event_roteiro GET    /app/events/:event_id/roteiros/:id(.:format)          app/roteiros#show
                   PATCH  /app/events/:event_id/roteiros/:id(.:format)          app/roteiros#update
                   PUT    /app/events/:event_id/roteiros/:id(.:format)          app/roteiros#update
                   DELETE /app/events/:event_id/roteiros/:id(.:format)          app/roteiros#destroy

                   ... omitting a bunch of routes ...

            events GET    /app/events(.:format)                                 app/events#index
                   POST   /app/events(.:format)                                 app/events#create
         new_event GET    /app/events/new(.:format)                             app/events#new
        edit_event GET    /app/events/:id/edit(.:format)                        app/events#edit
             event GET    /app/events/:id(.:format)                             app/events#show
                   PATCH  /app/events/:id(.:format)                             app/events#update
                   PUT    /app/events/:id(.:format)                             app/events#update
                   DELETE /app/events/:id(.:format)                             app/events#destroy



    event_arquivos GET    /events/:event_id/arquivos(.:format)              arquivos#index
                   POST   /events/:event_id/arquivos(.:format)              arquivos#create
 new_event_arquivo GET    /events/:event_id/arquivos/new(.:format)          arquivos#new
      edit_arquivo GET    /arquivos/:id/edit(.:format)                      arquivos#edit
           arquivo GET    /arquivos/:id(.:format)                           arquivos#show
                   PATCH  /arquivos/:id(.:format)                           arquivos#update
                   PUT    /arquivos/:id(.:format)                           arquivos#update
                   DELETE /arquivos/:id(.:format)                           arquivos#destroy

                   ... omitting a bunch of routes ...

            events GET    /events(.:format)                                 events#index
                   POST   /events(.:format)                                 events#create
         new_event GET    /events/new(.:format)                             events#new
        edit_event GET    /events/:id/edit(.:format)                        events#edit
             event GET    /events/:id(.:format)                             events#show
                   PATCH  /events/:id(.:format)                             events#update
                   PUT    /events/:id(.:format)                             events#update
                   DELETE /events/:id(.:format)                             events#destroy


但是，根据您的示例，您似乎希望使用
：event\u name
作为标识符，而不是
：event\u id
。在这种情况下，您将执行以下操作：


resources :events, param: :name do
  resources :arquivos, 
            :arquivos_items,
            :convidados, 
            :lista_convidados,
            :modelos, 
            :modelos_items, 
            :orcamento_items, 
            :orcamentos, 
            :providers, 
            :providers_items, 
            :reports, 
            :reports_items,
            :roteiros, 
            shallow: true
end


这将给你：


    event_arquivos GET    /events/:event_name/arquivos(.:format)            arquivos#index
                   POST   /events/:event_name/arquivos(.:format)            arquivos#create
 new_event_arquivo GET    /events/:event_name/arquivos/new(.:format)        arquivos#new
      edit_arquivo GET    /arquivos/:id/edit(.:format)                      arquivos#edit
           arquivo GET    /arquivos/:id(.:format)                           arquivos#show
                   PATCH  /arquivos/:id(.:format)                           arquivos#update
                   PUT    /arquivos/:id(.:format)                           arquivos#update
                   DELETE /arquivos/:id(.:format)                           arquivos#destroy

                   ... omitting a bunch of routes ...

            events GET    /events(.:format)                                 events#index
                   POST   /events(.:format)                                 events#create
         new_event GET    /events/new(.:format)                             events#new
        edit_event GET    /events/:name/edit(.:format)                      events#edit
             event GET    /events/:name(.:format)                           events#show
                   PATCH  /events/:name(.:format)                           events#update
                   PUT    /events/:name(.:format)                           events#update
                   DELETE /events/:name(.:format)                           events#destroy



我想这就是你要找的。
你好。非常感谢你的帮助。正如你所说，路线是如何运作的。但是当添加到项目的链接时，键入event_orcamentos_url我会得到错误：没有路由匹配{：action=>“index”，：controller=>“app/orcamentos”，：id=>“teste de evento”}，缺少必需的键：[：event_id]。我应该更改控制器中的某些内容以获取事件的id吗？我的控制器只获取特定项的id，如def set_orcamento@orcamento=orcamento.find（params[：id]）endI尝试使用event_orcamentos_url（@event），但当我转到link时，我没有得到任何路由匹配{：action=>“index”，：controller=>“app/orcamentos”，：event\u id=>nil}，路径中缺少必需的键：[：event\u id]：您可能应该使用
event\u orcamentos\u路径（@event）
。然后，您需要确保在控制器操作中设置了
@event
实例。看起来您可能没有设置
@event
，这就是您获得
：event\u id=>nil
的原因。此外，您还需要决定是使用
：id
还是
：name
作为标识符。如您所见这里：
没有与之匹配的路由{:action=>“index”，：controller=>“app/orcamentos”，：id=>“teste de evento”}
，看起来您试图使用
名称
作为
id
。
