The simplest way to trigger this warning (it's not Rails-related BTW) is this:
$ irb irb(main):001:0> class Foo irb(main):002:1> end => nil irb(main):003:0> Foo::Array.new (irb):3: warning: toplevel constant Array referenced by Foo::Array => [] So it seems that in addition to ActiveRecord::Base:Configuration there's another class called Configuration defined at the top level. Did you define this class? If not, does any of your dependencies define this class? Best regards -- Greg Navis I help small tech companies to scale Heroku-hosted Rails apps.
