How to setup api controller without the API version of Rails - ruby-on-rails

Question

I'm using Rails 5 to create an API but can not use the Rail 5 API only mode as I need Devise for user auth. Here's is how I have my first API controller setup:
routes.rb
Rails.application.routes.draw do
namespace :api do
namespace :v1 do
resources :skills
end
end
get '/*path' => 'home#index'
end
/controllers/api_controller.rb
class ApiController < ActionController::API
end
/controllers/api/v1/skills_controller.rb
class SkillsController < ApiController
def index
#skills = Skill.all
json_response(#todos)
end
def json_response(object, status = :ok)
render json: object, status: status
end
end
When I go to test this in the browser like so: http://localhost:4300/api/v1/skills.json
I'm getting the following errors in the rails log:
Started GET "/api/v1/skills.json" for 127.0.0.1 at 2017-05-25 08:44:12 -0700
TypeError (superclass mismatch for class SkillsController):

How can I set this up to work?

Answer 1

Set up your controller like this:
# /controllers/api/v1/skills_controller.rb
class Api::V1::SkillsController < ApplicationController
# fill in the rest
end
