"""
|
|
Serializers and ModelSerializers are similar to Forms and ModelForms.
|
|
Unlike forms, they are not constrained to dealing with HTML output, and
|
|
form encoded input.
|
|
|
|
Serialization in REST framework is a two-phase process:
|
|
|
|
1. Serializers marshal between complex types like model instances, and
|
|
python primitives.
|
|
2. The process of marshalling between python primitives and request and
|
|
response content is handled by parsers and renderers.
