How to programmatically list all controllers in Rails

Question

I'm trying to build a RESTful app to actually manage many kind of configurable objects, so there are a large amount of "resource" types, and hence a lot of controllers. I'm still at the POC phase, so it will be nice if I can show all controllers in a first navigation page, so any easy way (programmable) to do that?

Answer 1

You could certainly list the files in the controllers directory.

Answer 2

Google: 'rails list controllers'

First result.

After learning about the subclasses, I think the code from my link could be done simply as..

ApplicationController.subclasses.each do |c|
  puts "Controller: #{c}"
  puts "Actions: #{c.constantize.action_methods.collect{|a| a.to_s}.join(', ')}"
end

Answer 3

ApplicationController.subclasses

It'll get you started, but keep in mind that in development mode you won't see much, because it will only show you what's actually been loaded. Fire it up in production mode, and you should see a list of all of your controllers.
