Question

如果我通过向您展示我的路线来开始这个问题： -

c:\Sites\work\easygifts>rake routes

                 PATCH   /stores/:id(.:format)            stores#update
                 PUT     /stores/:id(.:format)            stores#update
                 DELETE  /stores/:id(.:format)            stores#destroy
        products GET     /products(.:format)              products#index
                 POST    /products(.:format)              products#create
     new_product GET     /products/new(.:format)          products#new
    edit_product GET     /products/:id/edit(.:format)     products#edit
         product GET     /products/:id(.:format)          products#show
                 PATCH   /products/:id(.:format)          products#update
                 PUT     /products/:id(.:format)          products#update
                 DELETE  /products/:id(.:format)          products#destroy
            root GET     /                                stores#index

我遇到的问题是将：id引入＆＃39;引用＆＃39;视图。

我想看看我的路线; quote_stores GET /stores/quote/:id(.:format）store＃quote或类似的东西。

可以：id只能通过CRUD传递吗？我以为我可以通过几乎任何地方传递实例变量，所以我在我的视图中将其写为视图的链接，其中：id信息传递给它。

    <% @products.each do |office| %>
        <div class="item">
            <%= link_to image_tag(office.image_url), image_path(office.image_url), class: 'fancybox' %>
            <p><strong><%= office.item_code%></strong>
            </br><em><%= truncate(office.title, length: 18) %></em></p>                 
            <p class="showArticle"><%= link_to 'Show Article', store_path(office) %></p>
            <p class="addTo"><%= link_to 'Price Info', quote_stores_path(office)  %></p>
        </div>
    <% end %>

我指的是＆lt;％= link_to＆＃39; Price Info＆＃39;，quote_stores_path（office）％＆gt;单击后，您将转到正确的视图，在URI路径中，它甚至列出了正确的：id，但它不会传递给视图：id＆＃39; s信息。

我的控制器代码如下： -

class StoresController < ApplicationController
    add_breadcrumb 'home', :stores_path


  def index
    @products = Product.all
  end

  def show
    @products = Product.find(params[:id])
      if @products.nil?
        redirect_to action: :index
      end
    add_breadcrumb 'Back', @products.section
  end

  def writing
    @products = Product.where(:section => 'writing').paginate(:per_page => 5, :page => params[:page])
    add_breadcrumb 'writing', writing_stores_path
  end

  def office
    @products = Product.where(:section => 'office').paginate(:per_page => 5, :page => params[:page])
    add_breadcrumb 'office', office_stores_path
  end

  def time
    @products = Product.where(:section => 'time').paginate(:per_page => 5, :page => params[:page])
    add_breadcrumb 'time', time_stores_path
  end

  def home
    @products = Product.where(:section => 'home').paginate(:per_page => 5, :page => params[:page])
    add_breadcrumb 'home', home_stores_path
  end

  def wellness
    @products = Product.where(:section => 'wellness').paginate(:per_page => 5, :page => params[:page])
    add_breadcrumb 'wellness', wellness_stores_path
  end

  def travel
    @products = Product.where(:section => 'travel').paginate(:per_page => 5, :page => params[:page])
    add_breadcrumb 'travel', travel_stores_path
  end

  def bags
    @products = Product.where(:section => 'bags').paginate(:per_page => 5, :page => params[:page])
    add_breadcrumb 'bags', bags_stores_path
  end

  def leisure
    @products = Product.where(:section => 'leisure').paginate(:per_page => 5, :page => params[:page])
    add_breadcrumb 'leisure', leisure_stores_path
  end

  def quote
        @products = Product.find_by(params[:id])
      if @products.nil?
        redirect_to action: :index
      end
  end
end

除了我的代码不干，我在这里找不到什么？我不理解的是什么：id＆＃39; s？

在你的config/routes.rb中，你可能有这一行：

resources :stores

为stores资源的标准CRUD操作创建路由。您可以为此资源定义其他操作，这些操作可以应用于集合（多个产品），也可以单独应用于成员（单个产品）。

请注意，为资源products而不是stores命名可能更符合逻辑，因为它似乎正在处理Products。

在您的情况下，您需要定义其他成员操作。由于它适用于单个产品，因此Rails将定义一个采用id参数的路由：

resources :stores do
  member do
    get 'quote'
  end
end

这将生成以下路线（rake routes）：

quote_store GET    /stores/:id/quote(.:format)     stores#quote

请注意，路线名为 quote_store ，是单数形式而非复数形式。

另见the Rails guides for more information about collection and member routes。
