I have created a simple Rails Engine to provide some general functionality(photo gallery) to an application. I want to be able to override the standard _header partial so that the menu for the gallery matches that of my main application. In my header view I call a helper that is part of application_helpers (main app), but I keep getting "undefined method" errors. From what I can tell the main app application_helpers are not being included (obviously) when I override the engines application layout or its partials.
So my question is, how do I override an engine view in the main application, and get access to the main application helper methods? I would still need access to the engine helpers as well as not to screw up the engine functionality.
Do I need to override the controllers as well? seem like a lot just to get some helpers.
Thanks

check out this blog post: http://www.candland.net/2012/04/17/rails-routes-used-in-an-isolated-engine/ The author adds a method_missing definition to the application helper in order to access the parent application's helpers.
