Ruby on Rails：Params问题

Question

I'm developing a job board where the companies can submit job ads With jobdescriptions_controller, I also have an uuid field as ID for the outside world called "applyjobid", but now for the outside world I have created jobdetails_controller in order to find the jobdescription.

So, when I goto http://localhost:3000/jobdetails/show?applyjobid=54da4118-0ba3-4375-ae87-6fa32201a369

I have this error : ActiveRecord::RecordNotFound at /jobdetails/show Couldn't find Jobdescription with 'id'=54da4118-0ba3-4375-ae87-6fa32201a369

If I go to http://localhost:3000/jobdetails/show?applyjobid=1 it works !!! but I really want to use uuid.

If you can tell me what is the problem, it would be very appreciated, thanks in advance.

end

routes.rb

Rails.application.routes.draw do

  devise_for :users

  root :to => 'dashbords#index'

thanks.

Answer 1

What's wrong here is you are finding by id as you are using find, and you are passing applyjobid So you have to use find_by_applyjobid

try this

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