Module: BigRecord::BrReflection::ClassMethods

Defined in:
lib/big_record/br_reflection.rb

Overview

Reflection allows you to interrogate Big Record classes and objects about their associations and aggregations. This information can, for example, be used in a form builder that took an Big Record object and created input fields for all of the attributes depending on their type and displayed the associations to other objects.

You can find the interface for the AggregateReflection and AssociationReflection classes in the abstract MacroReflection class.
