Add Avo behind Basic Authentication

Because in Rails we commonly do that using a static function on the controller we need to safely extend the controller to contain that function.

In actuality we will end up with something that behaves like this:

class Avo::ApplicationController < ::ActionController::Base
  http_basic_authenticate_with name: "adrian", password: "password"

  # More methods here
end

Safely add it to Avo

We described the process in depth in this article so let's get down to business.

1. Add the BasicAuth concern
2. The concern will prepend the basic auth method
3. include that concern to Avo's ApplicationController

WARNING

Ensure you restart the server after you extend the controller in this way.

# app/controllers/concerns/basic_auth.rb
module BasicAuth
  extend ActiveSupport::Concern

  # Authentication strategy came from this article:
  # https://dev.to/kevinluo201/setup-a-basic-authentication-in-rails-with-http-authentication-388e
  included do
    http_basic_authenticate_with name: "adrian", password: "password"
  end
end

# config/initializers/avo.rb
Avo.configure do |config|
  # Avo configuration
end

# Add this to include it in Avo's ApplicationController
Rails.configuration.to_prepare do
  # Add basic authentication to Avo
  Avo::ApplicationController.include BasicAuth
end
