but well none of my models uses activerecord what is happening here?

Issue solved with a little modification to application.rb changin
require rails/all for

require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "rails/test_unit/railtie"
require "sprockets/railtie"

and removing the white_list

and removing some lines from development.rb and
