Question

What do you recommend for displaying URLs and handling views in Rails for cities, regions, countries?

i.e:

/us/ca/San-Fransisco

/countries/us/regions/ca/cities/San-Fransisco

Should be able to: List all countries, list all regions within country and list all cities within a region and country.

Where would you put code for displaying all regions in a country?:

/us/regions/

/us

Should the code be in the region (action show) or country (action index) controller?

Answer 1

Agree with Arne. I don’t see any problem with the first variant.

As for the second question, you better get the list of regions in the RegionsController.

Say you want to

GET /us/regions 

then you should route it to

class RegionsController < ApplicationController   # GET /:country_code/regions   # GET /regions   def index     @countries =        if params[:country_code]         Country.find_by_code(params[:country_code]).regions       else         Region.all # get all regions if country_code is not set       end   end end
