Ruby on rails：問題與參數

Question

我正在開發一個工作板，公司可以通過jobdescriptions_controller提交招聘廣告，我也有一個uuid字段作爲外部世界的ID，名爲「applyjobid」，但現在是外部世界我創建了jobdetails_controller以便找到作業描述。

所以，當我轉到http://localhost:3000/jobdetails/show?applyjobid=54da4118-0ba3-4375-ae87-6fa32201a369

我有這樣的錯誤：的ActiveRecord :: RecordNotFound在/ jobdetails /顯示 無法與 'ID'= 54da4118-0ba3-4375-ae87-6fa32201a369

找到Jobdescription

如果我去http://localhost:3000/jobdetails/show?applyjobid=1它的作品！但我真的想用uuid。

如果你能告訴我什麼是問題，這將非常感激，在此先感謝。

class JobdescriptionsController < ApplicationController 
    layout 'application' 
    def new 
    @jobdescription = Jobdescription.new

    def create 
    @jobdescription = current_user.jobdescriptions.create(jobdescription_params)

end 

的routes.rb

Rails.application.routes.draw do 


    resources :tests 


    devise_for :users 
    resources :timesheets 
    resources :expenses 
    resources :jobdescriptions 
    resources :jobdetails 
    root :to => 'dashbords#index' 

謝謝。

Answer 1

什麼是錯在這裏是你被發現的ID，你正在使用的發現，和你逝去的applyjobid 所以，你必須使用find_by_applyjobid

試試這個

def show 
    @jobdetail = Jobdescription.find_by_applyjobid(params[:applyjobid]) 
end
