Module: MicroQ::Methods::ActiveRecord

Defined in:
lib/micro_q/methods/active_record.rb

Overview

Methods that are added to AR instances

When processing instance methods asynchronously, AR objects should not be stored. Instances that are backed by a database are herby serialized and re-queried from the DB at runtime. For AR that means simply storing the class and adding a custom ‘loader’

A Loader is an additional step before a method is invoked that generates a target object from a method invocation and arguments. In the case of AR, what better then ‘find’. Here we simply store the id as the argument for find.
