Overview

Used to validate an attribute in an AttrJson::Model whose values are other models, when you want validation errors on the nested models to post up.

This is based on ActiveRecord's own ActiveRecord::Validations::AssociatedValidator, and actually forked from it at https://github.com/rails/rails/blob/e37adfed4eff3b43350ec87222a922e9c72d9c1b/activerecord/lib/active_record/validations/associated.rb

We used to simply use an ActiveRecord::Validations::AssociatedValidator, but as of https://github.com/jrochkind/attr_json/pull/220 (e1e798142d) it got ActiveRecord-specific functionality that no longer worked with our use case.

No problem, the implementation is simple, we can provide it here, based on the last version that did work.
