Can Rails console reload modules under lib?

Question

I have a module in my Rails project under lib. I run \'rails c\' and do some experimenting in the console. I make a change to the module under lib, type \'reload!\' from the c

this is the monkeypatch that could help you, paste this in rails console (or you could put this code in a monkeypatch file - although I don't recommend monkeypatching Object with an utility method):

class Object
  def self.reload_myself!
    method = (self.instance_methods(false) + self.methods(false)).select{|method| method.to_s[0] =~ /[A-Za-z]/}.last
    if method
      if self.instance_methods(false).index method
        method = self.instance_method(method)
      elsif
        method =  self.method(method)
      end

      if (method.source_location)
        source_location = method.source_location[0]
        puts "reloading: #{source_location}"
        load "#{source_location}"
      else
        puts "could not reload #{self.name}"
      end
    end
  end
end

and you can call

reload_myself!

on any object to reload its source code.
