Warum hat has_one Assoziation mit verschachtelten Routen Zugriff auf alle möglichen Routen in der URL-Suchleiste?

Question

Ich bin verwirrt mit der Art und Weise, wie Sie jede URL wie deals /: id/properties /: id trotz einer Eins-zu-eins-Verbindung zwischen einem Deal und einer Eigenschaft bekommen können. Wie kommt es, dass ich in der Browser-URL deals/2/properties/14 eingeben kann (oder eine beliebige Kombination davon), wenn die mit deal 2 verknüpfte Eigenschaft die Eigenschaft 6 in meiner Datenbank ist. Die Links, die ich in den Ansichten habe, funktionieren und ich bekomme die richtigen Assoziationen/2/properties/6 über die Links, aber meine Frage ist da etwas, was ich falsch im Setup (oder überall sonst) gemacht habe oder ist das nur Rails erlaubt alles möglich Kombination, die im Browser getestet werden soll ... Wenn ja, gibt es eine Möglichkeit dies zu verhindern? Vielen Dank

Ich habe eine eins-zu-eins-Assoziation => 1 Deal hat eine Eigenschaft und eine Eigenschaft gehört zu behandeln. Ich habe Routen verschachtelt wie

resources :deals, only: [:index, :show, :create, :update, :destroy] do 
     scope '/siteadmin' do 
     resources :properties 
     end 
    end 

    scope '/siteadmin' do 
     resources :deals, except: [:index, :show] 
    end 

deal.rb folgt

class Deal < ApplicationRecord 
     has_one :property, dependent: :destroy 
     accepts_nested_attributes_for :property 
    end 

property.rb

class Property < ApplicationRecord 
     belongs_to :deal 
     validates :full_address, presence: true 
     validates_uniqueness_of :deal_id 
    end

die Routen behandelt nur die Format der Abfragezeichenfolge nicht die Werte darin.

, was ich tun Umfang sind die Daten in der Steuerung wie diese

class PropertiesController < ApplicationController 
    before_action :set_deal 
    before_action :set_property, only: [:show, :edit, :update, :destroy] 

    def index 
     @properties = Property.all.order(id: :asc) 
    end 

    def show 
    end 

    def new 
     @property = @deal.build_property 
    end 
    def create 
     @property = @deal.build_property(property_params) 
     if @property.save 
     flash[:notice] = "Property has been created." 
     redirect_to [@deal, @property] 
     else 
     flash.now[:alert] = "Property has not been created." 
     render "new" 
     end 
    end 
    def edit 
    end 

    def update 
     if @property.update(property_params) 
     flash[:notice] = "Property has been updated." 
     redirect_to [@deal, @property] 
     else 
     flash.now[:alert] = "Property has not been updated." 
     render "edit" 
     end 
    end 
    def destroy 
     @property.destroy 
     flash[:notice] = "Property has been deleted." 
     redirect_to @deal 
    end 
    private 
    def property_params 
     params.require(:property).permit(:genre, :surface, :nb_rooms, :nb_bedrooms, :city, :district, :full_address) 
    end 
    def set_property 
     @property = @deal.property #.find(params[:id]) # you don't need to find it because there is only 1 
    end 
    def set_deal 
     @deal = Deal.find(params[:deal_id]) 
    end 
    end
