I have a host app unicorn with the model Article.

I also have a mountable engine hooked into the host app called blorgh. It also has a model: Article. It is namespaced, so the table name for the engine's Article is actually blorgh_articles.

While inside the engine I want to grab the host app's article, not the engine's article. Is this possible?

#blorgh/app/controllers/blorgh/articles_controller.rb
require_dependency "blorgh_application_controller"
module Blorgh
  class ArticlesController < ApplicationController
    def index
      @articles = Article.all #properly grabs all the engine's articles
      @host_app_articles = main_app.Article.all # this doesn't work. It should grab the host app's articles.
    end
    ...
  end
end
