Extending controllers of a Rails 3 Engine in the main app

Question

I am using a Rails engine as a gem in my app. The engine has PostsController with a number of methods and I would like to extend the controller logic in my main

Answer 1

Why not just inherit from the Engine's controller class in your application (and point your routes at the new child controllers)? Sounds conceptually similar to the way that you extend built-in Devise controllers.
