Namespaces and inheritance in rails

I have an engine called Admin and a few controllers.

# admin/app/controllers/admin/application_controller.rb
module Admin
  class ApplicationController < ActionController::Base
  end
end

# admin/app/controllers/admin/foo_controller.rb
module Admin
  class CardsController < ApplicationController
  end
end

# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
end

If I visit my main app and THEN /admin the CardsController inherits from ApplicationController NOT Admin::ApplicationController. If I first visit /admin and then the main app it works.

I guess that when we first visit the main app the constant ApplicationController is created, which is then found and used when visiting /admin instead of loading Admin::ApplicationController.

How can one avoid this issue?

You'll have to be specific about which class you are inheriting from:

module Admin
  class CardsController < Admin::ApplicationController
    # ...
  end
end
