spec_helper.rb

#Some databases get upset if you try to start a new transaction while a transaction is already in play, so running the whole spec suite chokes when rspec is trying to start a transaction. You need to update your spec_helper to rely on active_record_spec_helper to do this for you.

#Replace this line
    config.use_transactional_fixtures = true

#With this
require 'active_record_spec_helper'

Did anyone came up with a solution to the question of georgemillo? I also struggle with the idea of loading all dependent models, which is undesireable to me.
