# 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 in most situations:
|
|
|
|
```ruby
|
|
# my_model.rb
|
|
class MyModel
|
|
alias :read_attribute_for_serialization :send
|
|
attr_accessor :id, :name, :level
|
|
|
|
def initialize(attributes)
|
|
@id = attributes[:id]
|
|
@name = attributes[:name]
|
|
@level = attributes[:level]
|
|
end
|
|
|
|
def self.model_name
|
|
@_model_name ||= ActiveModel::Name.new(self)
|
|
end
|
|
end
|
|
```
|
|
|
|
The [ActiveModel::Serializer::Lint::Tests](../../lib/active_model/serializer/lint.rb)
|
|
define and validate which methods ActiveModelSerializers expects to be implemented.
|
|
|
|
An implementation of the complete spec is included either for use or as reference:
|
|
[`ActiveModelSerializers::Model`](../../lib/active_model_serializers/model.rb).
|
|
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
|
|
attributes :id, :name, :level
|
|
end
|
|
```
|
|
|
|
The default serializer would be `MyModelSerializer`.
