How to serialize a Plain-Old Ruby Object (PORO)

When you are first getting started with ActiveModelSerializers, it may seem only ActiveRecord::Base objects can be serializable, but pretty much any object can be serializable with ActiveModelSerializers. Here is an example of a PORO that is serializable: “`ruby

my_model.rb

class MyModel alias :read_attribute_for_serialization :send attr_accessor :id, :name, :level

def initialize(attributes) @id = attributes @name = attributes @level = attributes end

def self.model_name @_model_name ||= ActiveModel::Name.new(self) end end “`

Fortunately, ActiveModelSerializers provides a ActiveModelSerializers::Model which you can use in production code that will make your PORO a lot cleaner. The above code now becomes: ruby # my_model.rb class MyModel < ActiveModelSerializers::Model attr_accessor :id, :name, :level end

The default serializer would be MyModelSerializer.
