Module: Knuckles::Stages::Renderer

Extended by:
Renderer
Included in:
Renderer
Defined in:
lib/knuckles/stages/renderer.rb

Overview

After un-cached models have been hydrated they can be rendered. Rendering is synonymous with converting a model to a hash, like calling ‘as_json` on an `ActiveRecord` model. Knuckles provides a minimal (but fast) view module that can be used with the rendering step. Alternatively, if you’re migrating from ‘ActiveModelSerializers` you can pass in an AMS class instead.
