Ruby namespacing

Question

I\'m pretty new to ruby, coming from a php background, but something is not clicking with me.

So, let\'s say I have a Ruby on Rails application and I am versioning m

Answer 1

I would rather suggest don't write ApplicationController in namespace, I would suggest to follow following

Note: If you are building professional api's it always good to have Api::V1::BaseController inheriting from ActionController::Base, though I am giving solution to your specific case

Ref this post: Implementing Rails APIs like a professional

1) Define application controller in usual way in app/controllers/application_controller.rb as

class ApplicationController < ActionController::Base
end 

2) Define base api controller namely Api::V1::BaseController in app/controllers/api/v1/base_controller.rb which will inherit from ApplicationController (your case) like

class Api::V1::BaseController < ApplicationController
end 

3) Define your api controllers like Api::V1::UsersController in app/controllers/api/v1/users_controller.rb which will inherit from Api::V1::BaseController

class Api::V1::UsersController < Api::V1::BaseController
end 

4) Add all subsequent controllers like Api::V1::UsersController (step 3)

Then routing will contain namespaces routing in config/routes.rb

namespace :api do
  namespace :v1 do
    resources :users do 
      #user routes goes here 
    end
    # any new resource routing goes here 
    # resources :new_resource do 
    # end
  end
end
