Can't add sub pages in a controller

Using RoR 2.3.8

This is my cities_controller.rb

class CitiesController < ApplicationController
  def show
    @city = City.find(params[:id])
    ...
  end

  def shops
    ...
  end

  def countries
    ...
  end
end
开发者_如何转开发

Here's my routes.rb

map.resources :cities, :collection => {:shops => :get, :countries => :get}

The show url for each id is:

http://localhost/cities/1

I want to have some contents shops and countries for each associated id, which I want:

http://localhost/cities/1/shops
http://localhost/cities/1/countries

I can't get the pages showed in empty code in the first place. What have I done wrong?

Thanks.

The :collection option is for when you want to act on the whole collection - so your routes will show up as:

http://localhost/cities/shops
http://localhost/cities/countries

What you want is

map.resources :cities, :member => {:shops => :get, :countries => :get}

Reference: http://apidock.com/rails/ActionController/Resources/resources

Shops and Countries would probably not be methods in the controller but other models. you would want a Countries.rb and Shops.rb

You would then nest the resources like

resources :cities do
     resources :shops
end

and you would need a belongs_to :city in the shops model and a has_many :shops in the cities model which would let you access cities/1/shops.... or something like that

However think about the way the data is structured, do countries really belong to cities (which nesting the resources would imply) or would countries contain cities. You would want cities belongs_to :country and so on...

This help?
