Hi Glenn,
When I have done something like this before, it has been by adding a hook
that keeps track whenever that code is included/invoked/etc. For example,
in a module I might have
module WhosThere
def self.included(klass)
@classes ||= []
@classes << klass
end
end
Then the WhosThere module has a list of all of the classes that have invoked
it.
For something like acts_as_solr where you don't want to touch the code
itself, you could do a monkey patch of some sort like
class ActiveRecord::Base
cattr_accessor :solr_classes
def acts_as_solr_with_hook
ActiveRecord::Base.solr_classes ||= []
ActiveRecord::Base.solr_classes << self
acts_as_solr_without_hook
end
alias_method_chain :acts_as_solr, :hook
end
You would then have your list in ActiveRecord::Base.solr_classes
(Caution, this code written off the top of my head, may need some tweaking
to actually get it to work)
