# i started with the following, which i thought would work with no problem:
AddOn.joins(:pricing_plans).joins(:subscriptions)
# returned this error:
# ActiveRecord::ConfigurationError:
# Association named 'subscriptions' was not found; perhaps you misspelled it?
# trying to get at it from the other direction:
PricingPlan.joins(:subscriptions).joins(:person)
# of course this didn't work either
# ActiveRecord::ConfigurationError: Association named 'person' was not found; perhaps you misspelled it?
