Question

我在我的应用程序中添加了一条到默认的restful路由的路由，所以在我的控制器中我有一个名为status的动作，它的动词是Patch，但每次我尝试更新属性时都会出现上述错误通过状态操作，注意：Restful路由中的默认更新操作没有问题。

的routes.rb

Rails.application.routes.draw do

  devise_for :users
  resources :projects do
    resources :gigs, shallow: true do
        patch :status
    end
  end
end

Gigs Controller

class GigsController < ApplicationController
  before_action :set_gig, only: [:show, :edit, :update, :destroy,:status]

  def status
    respond_to do |format|
      if @gig.update(:done, true)
        format.html { redirect_to @gig, notice: 'Gig was successfully updated.' }
        format.json { render :show, status: :ok, location: @gig }
      else
        format.html { render :edit }
        format.json { render json: @gig.errors, status: :unprocessable_entity }
      end
    end
  end

  private

    def set_gig         
      @gig = Gig.find(params[:id])
    end

    def gig_params
      params.require(:gig).permit(:name, :description, :done,:timeline)
    end
end

这是我添加到index.html.erb以执行更新

的链接

 <td><%= link_to 'Mark as Done', gig_status_path(gig), method: :patch %></td>

这是日志

您可以使用命令rake routes检查URI模式以进行状态操作。

         Prefix Verb   URI Pattern                              Controller#Action
     gig_status PATCH  /gigs/:gig_id/status(.:format)           gigs#status
   project_gigs GET    /projects/:project_id/gigs(.:format)     gigs#index
                POST   /projects/:project_id/gigs(.:format)     gigs#create
new_project_gig GET    /projects/:project_id/gigs/new(.:format) gigs#new
       edit_gig GET    /gigs/:id/edit(.:format)                 gigs#edit
            gig GET    /gigs/:id(.:format)                      gigs#show
                PATCH  /gigs/:id(.:format)                      gigs#update
                PUT    /gigs/:id(.:format)                      gigs#update

因此，您需要在状态操作

的情况下使用gig_id

修改方法set_gig，如下所示：

   def set_gig
      @gig = Gig.find(params[:gig_id])
    end

ActiveRecord :: RecordNotFound at / gigs / 2 / status无法找到带有＆＃39; id＆＃39; =
