Circular Dependency Error autoloading constant

I keep getting the error "Circular dependency detected while autoloading constant API::V1::CitysController" when I try load my api page. Everything I've searched seems to suggest their might be a typo but I don't think there is one.

My routes:

namespace :api , defaults: {format: 'json'} do
 namespace :v1 do
  resources :citys
 end
end

my controller is in app/controllers/api/v1/citys_controller.rb

Theres nothing in it really at the moment

class Api::V1::CitysController < ApplicationController
 respond_to :json

 def index

 end
end

Not sure what else is relevant to the problem? It should just load a blank page without any errors when I go to localhost:3000/api/v1/citys

Added routes

Prefix Verb   URI Pattern                      Controller#Action
  pages_home GET    /pages/home(.:format)            pages#home
        root GET    /                                pages#home
api_v1_citys GET    /api/v1/citys(.:format)          api/v1/citys#index {:format=>"json"}
             POST   /api/v1/citys(.:format)          api/v1/citys#create {:format=>"json"}
 new_api_v1_city GET    /api/v1/citys/new(.:format)      api/v1/citys#new {:format=>"json"}

             PATCH  /api/v1/citys/:id(.:format)      api/v1/citys#update {:format=>"json"}
             PUT    /api/v1/citys/:id(.:format)      api/v1/citys#update {:format=>"json"}
             DELETE /api/v1/citys/:id(.:format)      api/v1/citys#destroy {:format=>"json"}

I'm not sure why, but the error says it is looking for API::V1::CitysController class in your citys_controller.rb file and you have Api::V1::CitysController. So first and foremost change the name of your class to API::V1::CitysController (note the capitalized 'API'). That should solve your immediate problem.
