Fehler in meinem Ruby Code ... oder Rails Route?

Question

Ich bin relativ neu in Ruby-/ Rails und haben die Struktur einer case/when Klausel vermasselt oder vielleicht die Routen ich ... nicht verstehen

Fehler im Browser einfach: No route matches {:action=>"show", :controller=>"masters"}

aber eindeutig suchen bei rake routes ich sehe:

master GET /masters/:id(.:format) {:action=>"show", :controller=>"masters"} 
breeder GET /breeders/:id(.:format) {:action=>"show", :controller=>"breeders"} 

und beide (masters & breeders) Controller haben Arbeits show Methoden ...

Wo ist mein Gauner?

#app/controllers/dogs_controller.rb 
class DogsController < ApplicationController 

    def create 
    @parent = parent_object 
    @dog = @parent.dogs.create(params[:dog]) 
    puts parent_path 
    redirect_to parent_path(@parent) 
    end 

    def destroy 
    @parent = parent_object 
    @dog = @parent.dogs.find(params[:id]) 
    @dog.destroy 
    redirect_to parent_path(@parent) 
    end 

    private 

    def parent_object 
    case 
     when params[:master_id] then Master.find(params[:master_id]) && parent_path = master_path 
     when params[:breeder_id] then Breeder.find(params[:breeder_id]) && parent_path = breeder_path 
    end 
    end 
end 

Edit: Added MastersController

#app/controllers/masters_controller.rb 
class MastersController < ApplicationController 
    respond_to :html, :json 

    def index 
     respond_with(@masters = Master.all) 
    end 

    def show 
     respond_with(@master = Master.find(params[:id])) 
    end 

    def new 
     respond_with(@master = Master.new) 
    end 

    def edit 
     respond_with(@master = Master.find(params[:id])) 
    end 

    def create 
     @master = Master.new(params[:master]) 
     flash[:notice] = 'Master was successfully created.' if @master.save 
     respond_with(@master) 
    end 

    def update 
     @master = Master.find(params[:id]) 
     flash[:notice] = 'Master has been updated.' if @master.update_attributes(params[:master]) 
     respond_with(@master) 
    end 

    def destroy 
     @master = Master.find(params[:id]) 
     flash[:notice] = 'Successfully deleted master.' if @master.destroy 
     respond_with(@master) 
    end 
end

Ha! Fand es! Meine Weiterleitungen waren falsch ... sollte redirect_to @parent sein anstatt zu versuchen, einige parent_path(@parent) zu konstruieren, wie ich war ...
