Rails 5：事件系统

Question

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

这是我今天的路线：

  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 Event 模型相关联，然后每个事件都会有与之相关联的信息。

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

然后网址看起来像/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相关联

所有模型都已经有 event_id 值来关联

感谢您的帮助。

当前路线：

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

    resources :todo_lists do
      member do
        patch :complete
      end

      resources :todo_items do
        member do
          patch :complete
        end
      end
    end


  end

控制器

module App
  class OrcamentosController < SuperAppController
    before_action :set_orcamento, only: [:show, :edit, :update, :destroy]

    # GET /orcamentos

      @orcamentos = Orcamento.all

    def create
      @orcamento = Orcamento.new(orcamento_params)

      respond_to do |format|
        if @orcamento.save
          format.html { redirect_to orcamentos_path, notice: 'Orcamento inserido.' }
          format.json { render :show, status: :created, location: @orcamento }
        else
          format.html { render :new }
          format.json { render json: @orcamento.errors, status: :unprocessable_entity }
        end
      end
    end

    # PATCH/PUT /orcamentos/1
    # PATCH/PUT /orcamentos/1.json
    def update
      respond_to do |format|
        if @orcamento.update(orcamento_params)

          format.json { render :show, status: :ok, location: @orcamento }
        else
          format.html { render :edit }
          format.json { render json: @orcamento.errors, status: :unprocessable_entity }
        end
      end
    end

    # DELETE /orcamentos/1
    # DELETE /orcamentos/1.json
    def destroy
      @orcamento.destroy
      respond_to do |format|
        format.html { redirect_to orcamentos_url, notice: 'Orcamento removido.' }
        format.json { head :no_content }
      end
    end

    private
      # Use callbacks to share common setup or constraints between actions.
      def set_orcamento
        @event = Event.friendly.find(params[:id])
        @orcamento = Orcamento.find(params[:id])
      end

      # Never trust parameters from the scary internet, only allow the white list through.
      def orcamento_params
        params.require(:orcamento).permit(:title, orcamento_items_attributes: [:id, :desc, :estimado, :real, :pago, :pendente, :vencimento, :orcamento_id, :venc, :_destroy])
      end
  end
end

Answer 1

首先，您需要在嵌套项目前使用resources。类似的东西：

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

当您在控制台中运行 rake routes 时，会为您提供如下信息：

    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

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

class App::RoteirosController < ApplicationController 
  ...
end

该文件将位于：

app
 |- controllers
 |   |- app
 |   |   |- roteiros_controller.rb

我怀疑你不想要。所以，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docs in section 2.7.2 Shallow Nesting 中所讨论的，您可以考虑执行以下操作：

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，你会得到类似的东西：

    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，您似乎想使用 :event_name 而不是 :event_id 作为标识符。在这种情况下，你会这样做：

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

这会给你：

    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

我认为这就是您正在寻找的。​​p>
