Subject: Finding classes

I need to find classes that either:

1) Includes a specific module

or

2) Includes a specfic string in the class name

Either of the two is fine. This is in a Rails environment where I want to
find all classes using one of the two rules above. The problem is that the
classes I want to find probably aren't "required" at the time of searching
(ie ObjectSpace#each_object doesn't find them as far as I can tell and
Module#included hasn't been triggered).

Is it possible to do this?

Best regards,

Marcus


Tried this (doesn't work):

    class_names = Array.new
    ObjectSpace.each_object { |obj| class_names << obj.name if obj.is_a?(Class)
&& obj.name.include?("ChannelBehaviour") }
    behaviours = classes.uniq.map { |name| Class.const_get(name) }
