编辑多个记录、控制器和路由

Question

我正在关注 Railscast 198 http://railscasts.com/episodes/198-edit-multiple - 单独，尝试将其更新到rails 3，但遇到路由错误。路线 http://localhost:3000/orders/edit_individual 给我错误：

ActiveRecord::RecordNotFound in OrdersController#show - Couldn't find Order with ID=edit_individual

我已经更新并且使用他的rails 2路由

map.resources :products, :collection => { :edit_individual => :post, :update_individual => :put }

到rails 3约定，如engineyard http://www.engineyard.com/blog /2010/the-lowdown-on-routes-in-rails-3/ （根据我的需要更新）

  resources :orders do
    collection do
      post :edit_individual
      put :update_individual
    end
  end

这是我尝试过的：

我尝试按照答案的建议更改路线资源：<一个href="https://stackoverflow.com/questions/401241/adding-an-action-to-an-existing-controller-ruby-on-rails/401340#401340">向现有控制器添加操作（Ruby on Rails) 但仍然显示相同的错误。我尝试删除 cancan 加载和授权资源、“资源：订单”路由条目以及控制器中的“显示”条目，但另一个错误表明它仍在尝试显示 ID=“edit_individual”的记录而不是将“edit_individual”视为一条路线。

这是我的路线和控制器，

myapp::Application.routes.draw do

      resources :products

      resources :roles

      devise_for :users #, :controllers => { :registrations => "registrations" }

    #  match 'dashboard' => 'user_dashboard#index', :as => 'user_root'

      resources :orders do
        collection do
          post :edit_individual
          put :update_individual
        end
      end

      resources :orders   


class OrdersController < ApplicationController
    load_and_authorize_resource # cancan method

      def index
      end

      def show
      end

      def edit_individual #from railscast 198
        @orders = current_user.customer_orders
      end

      def update_individual
        @orders = Order.update(params[:orders].keys, params[:orders].values).reject { |p| p.errors.empty? }
        if @orders.empty?
          flash[:notice] = "Orders updated"
          redirect_to orders_url
        else
          render :action => "edit_individual"
        end
      end # ...etc.

我已经删除了 cancan 方法，但它仍然是罪魁祸首吗？我已经尝试了我能想到的一切，但陷入了死胡同……有什么想法吗？

编辑：

命令提示符的输出：

以及我的 html 中的路线：

    <%= link_to 'Update Payments Received', edit_individual_orders_path %>

和 rake 路线：

 update_individual_orders PUT    /orders/update_individual(.:format)       {:action=>"update_individual", :controller=>"orders"}

                          PUT    /orders/:id(.:format)                     {:action=>"update", :controller=>"orders"}
                          DELETE /orders/:id(.:format)                     {:action=>"destroy", :controller=>"orders"}

Answer 1

您可能应该运行“rake paths”并查看它为“edit_individual”操作提供的路线。

另外，您的日志

Started GET "/orders/edit_individual" for 127.0.0.1 at Thu Jun 30 11:19:02 -0700

表明您正在将后操作调用为 get。

尝试下面

  resources :orders do
    collection do
      get :edit_individual
      put :update_individual
    end
  end

或者您可以使用的任何一种方式

<%= link_to 'Update Payments Received', edit_individual_orders_path, :method => "post" %>

Answer 2

因此，错误消息：OrdersController#show - Couldn't find Order with ID=edit_individual 告诉我，无论出于何种原因，您都会被路由到“show”操作，该操作本质上期望类似于

/orders/1

表示它是成员而不是集合的内容。您确定服务器输出中点击的 url 与 /orders/edit_individual 匹配吗？
