Rails URLs goes backwards

Question

I am having a weird problem. I have two models in my app, downtowns and properties. Downtowns should have multiple properties and properties should have one downtown.

On my downtown show page i loop through the properties through each downtown and then offer links to these properties.

Problem is.....when i click on each property, the url goes backwards. IE, a downtown with an ID of 1 and a property with an ID of 8 should go

downtown/1/properties/8

yet it keeps going

downtown/8/properties/1

I think this is so weird and i have no clue what i've been doing wrong here.

On my downtown show page, i loop through each property

%h2= @downtown.name
- if @downtown.properties.present?
  %p 
    - @downtown.properties.collect do |property|
      = link_to property.name, downtown_property_path(property)

- else
  No downtowns for now.

My routes are the basic nested routing here

  resources :downtowns do
    resources :properties
  end

my properties controller is

class PropertiesController < Downtown::ApplicationController
  before_action :find_property, only: [:show, :edit, :update, :destroy]

  def new
    @property = @downtown.properties.new
  end

  def create
    @property = @downtown.properties.new(property_params)

    if @property.save
      redirect_to @downtown
    else
      render :new
    end
  end

  def show
  end

  private

  def property_params
    params.require(:property).permit(:name, :downtown, :downtown_id......)
  end

  def find_property
    @property = Property.find(params[:id])
  end
end

My downtown controller is

class DowntownsController < ApplicationController
  before_action :find_downtown, only: [:show, :edit, :update, :destroy]

  def show
    @properties = Property.where(downtown: @downtown_id)
  end

  def new
    @downtown = Downtown.new
  end

  def create
    @downtown = Downtown.create(downtown_params)
    if @downtown.save
      redirect_to @downtown
    else
      render 'new'
    end
  end

  private

  def downtown_params
    params.require(:downtown).permit(:name, :city)
  end

  def find_downtown
    @downtown = Downtown.find(params[:id])
  end  
end

Finally in my properties form i have a polymorphic path

= simple_form_for([@property, @downtown]) do |f|
  = f.input :name
  = f.input :last_remodel
  = f.input :original_construction_year

Nested route path take multiple arguments Rails Guide.

In your case, it should be downtown_property_path(@downtown, property)
