Automatically get a list of controller names

Okay, just a follow up question: is there an automatic way to make an array of all controller names? So that I could use this in the user model to validate the user doesn't type in any of the controller names.

(This is a continued conversation of one that asked about making routes this way:

domain.com/username

but still retaining the functionality to send the user to a controller if they typed:

domain.com/controllername

@conts_and_meths =   controllers = Dir.new("#{RAILS_ROOT}/app/controllers").entries   controllers.each do |controller|     if controller =~ /_controller/ and not controller.index("\.swp") then       cont = controller.camelize.gsub(".rb","")       meths = (eval("#{cont}.new.methods") - ApplicationController.methods - Object.methods - ApplicationController.new.methods).sort       @conts_and_meths << [cont, meths]     end

This gives you the methods too, but you can see how you would just get the controllers if you wanted. Careful, this is not stuff you want to expose to everybody.

I would recommend that you hard-code that list and also include controller names you may use in the future and reserved or restricted words.

I have this bad habit of "starring" (gmail) messages and forgetting to get back to it. Better late than never. Thanks jasoo and willhaslett!
