Getting the ID of a Model that Uses Nested Routes and Permalinks in Rails -

So I had my ID set with ID like:

  resources: studio Doing Resources: Booking Finished  

This gave me the route of the index (which later I am going to use Jasonson to get the calendar for each studio.

  Studio_Bookings GET / Studio /. Studio_ID / Bookings (. Format: Booking # Index)  

This is good, but I was getting rid of the ID and wanted to use a user account instead to change it to a friendly URL.

Namespace: Studio, Path = & gt; ; '/: Permalink' Resource: Complete booking:

I am getting now

  Get Studio_bookings /: paramlink / bookings (.format) Studio / Booking # Index  

Great! How do I want to see my URL, though, now: Not anywhere on the id route I have found

  Booking can not be found without ID  

This is not being passed too. is there any way? To pass: IDs in the URL without actually using the URL? Otherwise, can I change the primary key from: id: permalink to fix it?

I tried changing my controller from

  @studio = Studio.find to Params [: id])  

  @studio = studio.find (Parameters [: permalink])  

but gives me

  id Booking with '= 40frost  

has not been found which tells me what I am doing is not actually what to do? It is trying to keep permalink in the form of ID, although I am asking the rail to see the paramike, it still appears that it is looking at ID.

Hopefully my problem is clear: Essentially - how can I pass the ID, so that it knows that it is not displayed in the studio url If there is some controller magic then I can be flexible instead.

Here's my controller for good measure

  class studio :: booking controller & lt; ApplicationController before_action: set_booking, only: [: show, edit, update: deleted] #GET / booking #GET /bookings.json dnf index @ studio = studio.find (param [: permalink]) @ bookings = booking. Where ("Studio_ID = & gt; 'Studio.ID'") End # GET / Booking / 1 # GET / Bookings / 1.Jason Def Show End # GET / Booking / New Def New @ Booking = Booking.New and # GET / Booking / 1 / edit def editing end # POST / booking # POST / bookings.json def @ booking = booking.news (booking_parms) response_to do | Format | If booking @ save.change format.html {bookmark_to @booking, notice: 'booking was successfully created.' } Format.json {Render Action: 'Show', Status :: Created, Location: @Booking} and Format Html {animation: 'new'} format.json {json: @ booking. Errors, Status :: unprocessable_entity} End & End # Patch / Pet / Booking / 1 # Patch / Put / Bookings / 1 JSN DIF Update Reply-To-Do | Format | If @ booking.update (booking_parms) format.html {redirect_to @booking, notice: 'booking was successfully updated.' } Format.json {head: no_content} else format.html {render action: 'edit'} format.json {json: @ booking Errors, Status :: unprocessable_entity} End & # DELETE / Booking / 1 # Deletion / Booking / Booking 1.json DEF @. Update response_to do format | Format.html {redirect_to bookings_url} format.json {head: no_content} Use Callback to share common setup or interruptions between end-end personal # functions Def set_booking @booking = booking.find (params [: permalink]) End # Scary Do not trust the criteria from the Internet; Allow only through white list Def booking_param params.require (booking) .Permit (: start_time,: end_time ,: studio_id,: engineer_id,: title, allday) End end  

you just You can model, or you can

  self.primary_key = 'permalink' in studios  
  Def index @studio = Studio.find_by permalink: params [: permalink] @bookings = Booking.where (studio_id: @ studio.id) End  
 
 Depends if you are just locally Want to change behavior or always want to describe the studio model by permalink. 
 
 Hope that helps!
