The purpose of `ActiveModel::Serializers` is to provide an object to encapsulate serialization of `ActiveModel` objects, including `ActiveRecord` objects.

Purpose

The purpose of ActiveModel::Serializers is to provide an object to encapsulate serialization of ActiveModel objects, including ActiveRecord objects.

Serializers know about both a model and the current_user, so you can customize serialization based upon whether a user is authorized to see the content.

In short, serializers replaces hash-driven development with object-oriented development.
