Ruby 在 rails 上：参数问题

Question

我正在开发一个工作板，公司可以在其中提交招聘广告使用 jobdescriptions_controller，我还有一个 uuid 字段作为外部世界的 ID，名为 "applyjobid"，但现在用于外部我创建 jobdetails_controller 的世界是为了找到职位描述。

所以，当我转到 http://localhost:3000/jobdetails/show?applyjobid=54da4118-0ba3-4375-ae87-6fa32201a369

我有这个错误：ActiveRecord::RecordNotFound 在 /jobdetails/show 找不到 'id'=54da4118-0ba3-4375-ae87-6fa32201a369

的职位描述

如果我去 http://localhost:3000/jobdetails/show?applyjobid=1 就可以了！！！但我真的很想用uuid。

如果你能告诉我问题是什么，将不胜感激，提前致谢。

jobdescriptions_controller.rb

class JobdescriptionsController < ApplicationController
  layout 'application'
  def new
    @jobdescription = Jobdescription.new
  end
  def create
    @jobdescription = current_user.jobdescriptions.create(jobdescription_params)
    redirect_to new_jobdescription_path
  end
private
  def jobdescription_params
    params.require(:jobdescription).permit(:applyjobid, :job_title,  )
  end
end

jobdetails_controller.rb

class JobdetailsController < ApplicationController
  layout 'application'

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


end

routes.rb

Rails.application.routes.draw do


  resources :tests


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

谢谢。

Answer 1

这里有什么问题是你在使用 find 时通过 id 查找，而你传递的是 applyjobid 所以你必须使用 find_by_applyjobid

试试这个

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