Creating Custom Shapeless Serializers

For developers who need only specific features, you can create your own serializer combinations by mixing individual components.

Why Build Custom Serializers?

Reduce overhead by including only what you need
Create specialized serializers for different parts of your application
Maintain finer control over serializer behavior

Available Mixins

Mixin	Description
`DynamicFieldsMixin`	Select which fields to include at runtime
`DynamicFieldAttributesMixin`	Modify field attributes (read_only, write_only, etc.)
`DynamicFieldRenamingMixin`	Rename output fields without changing models
`DynamicNestedSerializerMixin`	Configure nested relationships dynamically
`DynamicConditionalFieldsMixin`	Include/exclude fields based on conditions

Basic Custom Serializer Examples

Field Selection Only

from rest_framework import serializers
from shapeless_serializers.mixins import DynamicFieldsMixin

class LightweightSerializer(DynamicFieldsMixin, serializers.Serializer):
    """Only includes dynamic field selection"""
    pass

Field Selection + Renaming

from rest_framework import serializers
from shapeless_serializers.mixins import (
    DynamicFieldsMixin,
    DynamicFieldRenamingMixin
)

class ReportingSerializer(DynamicFieldsMixin,
                        DynamicFieldRenamingMixin,
                        serializers.ModelSerializer):
    """For external reporting with custom field names"""
    pass

Nested Relationships Only

from rest_framework import serializers
from shapeless_serializers.mixins import DynamicNestedSerializerMixin

class NestedOnlySerializer(DynamicNestedSerializerMixin,
                          serializers.ModelSerializer):
    """Just handles dynamic nested relationships"""
    pass
