activerecord_json_validator | validate JSON attributes against a JSON schema | JSON Processing library

I'm doing a rails setup with Single Table Inheritance, where each class has all of it's attributes stored on a JSON blob, the structure of which is defined in a json schema file unique to that class.

I want to run validations on each class against its json schema but the logic is the same for every class minus the path to the schema itself which depends on the name of the STI class and the sub class.

This setup relies on the gem 'activerecord_json_validator' which specifies a format for the validation schema files and some helpers for validation

So the desired setup is something like

/app/models/data_generating_module (the abstract STI base class which is never instantiated)
