How to find if my app is loading an Engine?

Question

Having this in routes.rb

mount Ckeditor::Engine => '/ckeditor'

Since the ckeditor gem's controllers inherit from my ApplicationController, how can I find inside it that those are the controllers that are being loaded?

I need this because I found out that my ApplicationController is overriding the layout declaration and thus breaking the gem.

So far tried using request.original_url to check if "ckeditor" is present but it doesen't work out because when the engine is being loaded that part is 'ripped off'...

Answer 1

Run rake routes. It tells you about the routes in mounted engines.

Answer 2

For this specific case, there is a method respond_with_asset defined inside the engine's ApplicationController so I'm simply doing:

if defined? respond_with_asset
