I want to take the results of a pl/pgsql function, that returns a set of records and user AMS to serialize the results. How can I do this?

The primary usage of Active Model Serializers is to create custom JSON responses. By default, Rails provides a way to render JSON, but we need a serializer if we want to customize it.
Serialization converts an object in memory into a stream of bytes that can be recreated when needed. Serializers in Ruby on Rails convert a given object into a JSON format. Serializers control the particular attributes rendered when an object or model is converted into a JSON format.
Active Model is a library containing various modules used in developing classes that need some features present on Active Record.
A serializer is an object responsible for transforming a Model or Collection that's returned from your route handlers into a JSON payload that's formatted the way your frontend app expects. For example, this route handler returns a Movie model: this. get("movies/:id", (schema, request) => { return schema.
AMS can serialize a Plain-Old Ruby Object. AMS provides ActiveModelSerializers::Model which can easily make a PORO a serializable object by doing this:
class MyModel < ActiveModelSerializers::Model
attributes :id, :name, :level
end
MyModelSerializer would be the default serializer.
